Abstract

Species of Trissolcus Ashmead are potent natural enemies of stink bugs (Pentatomidae). Research on biological agents to control the brown marmorated stink bug, Halyomorpha halys (Stål) (BMSB), in Western Europe requires reliable taxonomic resources for identification of Trissolcus wasps. To aid this research endeavor, we present a species identification key to females of Palearctic Trissolcus. Morphological characters and concepts of the genus and species groups are discussed. We discovered a number of nomenclatural and identification issues that we here rectify.

Introduction

The introduction of the brown marmorated stink bug (BMSB) (Halyomorpha halys Stål; Hemiptera: Pentatomidae) into the Eastern United States, followed by invasion on the West Coast, prompted interest in Trissolcus as a classical biological control agent with emphasis on two species, T. cultratus (Mayr) and T. japonicus (Ashmead). Recent work in this genus (Talamas et al. 2015a) provided identification tools to separate these species from the Nearctic fauna. This work followed relatively recent revisions of Nearctic Trissolcus (Johnson 1984a, 1985a–b) that made production of these tools a straightforward task. The second taxonomic component of this project is species-level revision of Trissolcus to enable identification of T. japonicus and T. cultratus in their native ranges. The expansive distributions of some species, including T. cultratus, led us to revise the genus for the entire Palearctic region. Some species extend to Southeast Asia and we here include species from this region for which we directly examined primary types.

BMSB has recently become established in Europe (Wermelinger et al. 2008) where its range continues to expand (Haye et al. 2015). In light of this, revision of Trissolcus from this region has assumed greater urgency. With this publication we provide Europe, Asia, and the Middle East with the basic tools of species identification that facilitate molecular diagnostics and research on host selection, species evolution, and biological control.

Criticism of previous taxonomy

Our quest to identify species of the Eastern Palearctic revealed that multiple species range from Western Europe to East Asia, requiring evaluation of material from the entire Palearctic region. In the process we discovered deep-rooted problems in the taxonomy of the group, many of which stem from insufficient or nonexistent examination of primary types. Species descriptions have typically been based on a small number of specimens from a restricted geographic area, and were not part of a thorough revisionary effort. As a result, most of the available names in the Palearctic are synonyms. The detrimental consequences of this are significant and difficult to overemphasize, as they put an incredible strain on taxonomists that are already faced with a formidable array of biodiversity to describe and understand. To be sure, it forces the time consuming loan of type specimens, creates literature with confusing or erroneous name usage, and prevents an accurate understanding of the true diversity within the genus and the distributions of its constituent species. Evaluation of Trissolcus for biological control of BMSB in Europe simply cannot progress without the ability to properly identify the species under study.

The above mentioned issues in Trissolcus are directly relevant to establishing proper name usage for T. japonicus, the primary candidate for biological control in the United States. Trissolcus halyomorphae was carefully characterized in the description by Yang (2009), but its identity as T. japonicus (Ashmead) was not recognized because no primary types were examined. Buhl (1996) apparently examined a single specimen of Trissolcus, which he correctly keyed to the couplet of T. cercus and T. pontus in Kozlov (1978), but nonetheless described the species, T. dobashii, as new. We here treat all three (T. cercus, T. pontus and T. dobashii) as junior synonyms of T. japonicus. Kononova (2014) and her concept of the flavipes group was produced seemingly unaware of Talamas et al. (2013) or Yang (2009) as she redescribed T. japonicus as T. mirus.

Reliance on erroneous literature alone, without reassessment of type material, has compounded taxonomic problems in Palearctic Trissolcus. For example, Trissolcus cultratus (Mayr), originally described as Microphanurus cultratus Mayr, was erroneously treated by Kozlov (1968) as a junior synonym of Trissolcus flavipes. Kozlov subsequently perpetuated the concept of T. cultratus, a distinctive and easily recognized species, under the name T. flavipes. The concept of T. flavipes that we provide here is a trans-Palearctic species which was redescribed as T. circus by Kozlov and Lê (1976) and as T. crassus by Kononova (2014).

The key to species by Kozlov (1978) treats most of the Palearctic fauna, but ignores pleural characters entirely and in some cases the couplets do not match specimens from the type series. We suspect that many of the identification keys are simply regurgitations of previous works without contributing new knowledge to an understanding of the group. Specimen size and distribution were frequently used for identification, precluding the possibility of large distributions or size differences caused by emergence from different host species. Based on our experience comparing the identification keys of Kozlov, Petrov (2013), and Kononova to primary types and specimens from a broad geographic distribution, we recommend that these publications be avoided, as they do not accurately enable species identification. We suspect that all of the species described by Kononova (2014) will be treated as junior synonyms once the material is fully assessed.

Our experience with Trissolcus leads us to believe that other groups in Platygastroidea (esp. Platygastrinae and Telenomus) are likely to harbor large numbers of trans-Palearctic species that have been described multiple times.

Materials and methods

The locality data reported for primary types are not literal transcriptions of the labels: some abbreviations are expanded; additional data from the collectors are also included. The numbers prefixed with “USNMENT” or “ZMAS” are unique identifiers for the individual specimens (note the blank space after some acronyms). Details on the data associated with these specimens may be accessed at the following link, purl.oclc.org/NET/hymenoptera/hol, and entering the identifier in the form. The taxonomic synopsis was generated by the Hymenoptera Online Database (hol.osu.edu).

Photographs were captured with a Z16 Leica®™ lens with a JVC KY-F75U digital camera using Cartograph®™ software, or a Leica®™ DMRB compound microscope with a GT-Vision®™ Lw11057C-SCI digital camera attached. In both systems, lighting was achieved using techniques summarized in Buffington et al. (2005), Kerr et al. (2009) and Buffington and Gates (2009). Single montage images were produced from image stacks with the program CombineZP®™. In some cases, multiple montage images were stitched together in Photoshop®™ to produce larger images at high resolution and magnification. Full resolution images are archived at the image database at The Ohio State University (http://purl.oclc.org/NET/hymenoptera/specimage) and MorphBank (http://www.morphbank.net).

The specimen(s) that formed the bases for concepts of species that we here treat as junior synonyms are provided in Morphbank collections following the act of synonymy for each species. The Morphbank collection for the valid name contains all images of that species, including the types of junior synonyms.

Morphological terms were matched to concepts in the Hymenoptera Anatomy Ontology using the text analyzer function. A table of morphological terms and URI links is provided in Suppl. material 1.

Character discussions

Clypeal setae

The number of setae on the clypeus is at times a challenging character to observe, but it is very useful for delimiting the flavipes group and separating similar species within it. Consistent with Talamas et al. (2015a), species in the flavipes group have 4 or fewer clypeal setae, and those in the thyantae group have 6. We find that the number of clypeal setae in the basalis group is almost always 6, but we encountered a small number of specimens of T. comperei with 8 clypeal setae. Scanning electron microscopy revealed that in addition to the two prominent clypeal setae, T. cultratus has a pair of extremely small setae that are not visible with light microscopy. We here clarify that our treatment of these setae is based on brightfield microscopy, and note that the actual number of setae may vary when analyzed in an SEM.

Episternal foveae

In our revisionary efforts, we found no explicit mention of episternal foveae, nor are we aware of their use in any identification tools for Palearctic Trissolcus. The separation, or lack thereof, of the episternal foveae from the postacetabular sulcus and mesopleural pit, as well as their presence or absence, is relatively easy to interpret and has great diagnostic utility in Trissolcus.

Subacropleural sulcus

We here coin the name subacropleural sulcus for the line of foveae anterior to the prespecular sulcus that extends from the acropleural sulcus toward the mesopleural pit (Figures 5, 153).

Posterodorsal metapleural sulcus

Directly ventral to the metapleural carina there is often a line of cells in Scelionidae (Figs 5, 139, 189). We here coin the name posterodorsal metapleural sulcus for this character. In many species this sulcus is a clearly defined line of cells, whereas in others its definition is challenged by coarse sculpture or irregular forms of the cells that comprise the sulcus.

Generic diagnosis of Holarctic Trissolcus

The characters presented in Talamas et al. (2015a) will separate most, but not all, species of Palearctic Trissolcus from Telenomus. A four-merous clava is found in T. hyalinipennis and T. oobius, compounded by as many as 6 clavomeres that can be found in Telenomus. Trissolcus perepelovi and T. plautiae have a frons that can be largely smooth, reducing the reliability of a sculptured frons as a diagnostic character for Trissolcus. The ratio of width to length of T2: wider than long in Trissolcus and longer than wide in Telenomus, remains unequivocal in the Palearctic region as far as we know.

In the Nearctic, we encountered a species of Telenomus (USNMENT01197254), reared from lepidopteran eggs, with a 5-merous clava and T2 wider than long. This species can easily be separated from Trissolcus by an occipital carina that extends to the anterior articulation of the mandible. In all Holarctic Trissolcus, the occipital carina extends to the posterior articulation of the mandible.

The subacropleural sulcus is present in all species of Holarctic Trissolcus with the sole exception of T. exerrandus. We have yet to thoroughly examine Telenomus from the Palearctic region, and thus cannot give a complete analysis of this character’s diagnostic power, but nonetheless we consider it to be a useful generic character for Trissolcus.

Species groups

The creation of species-groups can be very useful for identifying subgeneric lineages that represent monophyletic groups or morphologically similar clusters of species. However, as more species are examined, many species cannot be placed in species-groups without drastically altering their limits. Trissolcus stoicus presents a challenge to our concepts of species-groups because it exhibits characters suggesting relation to both the flavipes and thyantae groups. The complete hyperoccipital carina aligns it with the flavipes group, but it has 6 clypeal setae. The posteroventral metapleuron has 2 large setae, perhaps an intermediate form between the glabrous metapleuron of the flavipes group and the dense setation typical of the thyantae group. This species also lacks notauli and well-defined episternal foveae of the thyantae group and we here do not treat it as part of any species group. As the taxonomic treatment of Trissolcus expands geographically, the concepts of species groups will likely require modification, as has occurred following our revision of the Palearctic species.

basalis species group

The basalis species-group in the context of the Nearctic fauna was defined by a glabrous metapleuron and the absence of a hyperoccipital carina. We here continue to approach this cluster of species as the basalis group, although where the basalis group ends become increasingly blurry as more species are examined, particularly in Southeast Asia.

flavipes species group

Multiple species in the flavipes group from the Palearctic region do not comply with the characters in the key to species of Nearctic Trissolcus by Talamas et al. (2015a). The notaulus may be very weakly indicated and present only at the posterior margin of the mesoscutum, as in T. gonopsidis, and the hyperoccipital carina in T. eriventus may be unrecognizable. Use of these characters is further complicated by species with a hyperoccipital carina that are well outside of the flavipes group (T. carinifrons and T. stoicus). Regarding the Holarctic fauna and what we have seen from Southeast Asia, the number of clypeal setae (4 or fewer) is the most reliable character for identifying the flavipes group and is the primary character that we use for its delimitation.

Kononova (2014) presented a new concept of the flavipes species group, one based on a postmarginal vein longer than the stigmal vein. The vast majority of species in Trissolcus have this form of wing venation, and thus this concept offers very little for subgeneric classification or identification. We prefer more restrictive species group concepts because they enable us to produce more efficient identification tools. However, there is presently no objective basis for selection of one species-group concept over another because there is no phylogeny to demonstrate which, if any, of the concepts correspond to monophyletic groups.

thyantae species group

The thyantae species-group in the Nearctic is characterized by setae in the posteroventral portion of the metapleuron, presence of notauli, episternal foveae present as large, distinct cells that are often elongate horizontally and form a continuous line from the dorsal limit of the postacetabular sulcus (or acetabular carina) to the mesopleural pit, a transversely strigose speculum, and six clypeal setae. These characters are valid for the Palearctic species, but there are some notable species (T. larides, T. levicaudus, T. tersus) with a densely setose metapleuron that lack the other defining characters of the thyantae group. Some of these species are also morphologically close to species that lack setation of the metapleuron. We here choose not to expand the concept of the thyantae group to include all species with a setose metapleuron until additional phylogenetic analysis determines whether or not this character delimits a monophyletic lineage.

The relationships between species of the thyantae group across the Northern Hemisphere warrant further investigation. We here present a concept of T. scutellaris that contains a great deal of variation in the sculpture of the frons, mesoscutum and mesoscutellum, and in the degree of development of the mesopleural carina. Among the specimens at hand there is a continuous gradient of sculptural development, and clear lines cannot be drawn between T. scutellaris and the species that we treat as junior synonyms. In the Nearctic, these characters appear to be fixed and are thus used in species diagnosis. We were unable to find morphological characters to separate the more rugose specimens of T. scutellaris (Palearctic) from T. ruidis Johnson (Nearctic), and the smoother specimens from T. valkyria Johnson & Talamas (Nearctic). We refrain from treating the Nearctic species as junior synonyms at this time because of their disjunct distributions and the possibility that these are cryptic species. Molecular data will undoubtedly be useful in determining how well our morphological species concepts match concepts generated from DNA data; the combination of these data will help determine with greater confidence if T. scutellaris is a Holarctic species.

Illumination

High quality optics and bright, diffuse lighting are necessary for observing the characters in this key. The authors recommend fluorescent desk lamps, or fiber optic lamps with a mylar shield between the tip of the light pipes and the specimen. The mylar should be placed close to the specimen, with the light source approximately 10 cm from the mylar (Figures 1–2) for the optimal light-scattering effect. The characters used in this key are evaluated with brightfield microscopy.

Comments

The holotype specimen consists of a metasoma and a wing, which are insufficient to separate this species from other species of Trissolcus, nor can it be confidently distinguished with the descriptions by Dodd (1920) and Nixon (1938). The condition of the type is so poor that designation of a neotype is warranted. However, this is confounded by the host association on the holotype labels that indicate that it emerged from the egg of a hawk moth (Sphingidae)- which is most likely an error. In the absence of material from vicinity of the type locality required for designation of a neotype, we presently treat T. barrowi as nomen dubium.

Diagnosis

Among Palearctic species of Trissolcus, T. basalis is most similar to T. semistriatus with which it shares episternal foveae that are distant from both the postacetabular sulcus and the mesopleural pit and an absence of coarse macrosculpture on the mesoscutum and mesoscutellum. The best feature for separating these species is the netrion sulcus, which is dorsally complete in T. semistriatus (Figures 170, 171) and dorsally undefined in T. basalis (Figure 22). The postacetabular sulcus in T. basalis is typically indicated by small and poorly defined cells, sometimes appearing as a smooth furrow. In T. semistriatus the cells of the postacetabular sulcus are distinct and regularly spaced. The mesoscutal humeral sulcus in T. basalis is always present as a smooth furrow whereas in T. semistriatus it is nearly always comprised of distinct cells. Trissolcus basalis is also similar to T. elasmuchae, from which it can be separated by the absence of a well-defined paracoxal sulcus in the ventral half of the metapleuron, and by the form of the episternal foveae, which in T. elasmuchae from a more or less continuous line from the postacetabular sulcus to the mesopleural pit.

Diagnosis

Trissolcus comperei is similar to T. yamagishii, T. latisulcus, and T. carinifrons with which it shares a long dark radicle and coarse sculpture of the mesoscutum and mesoscutellum. Trissolcus comperei can be separated from them by the characters presented in the key: sculpture of the frons below the median ocellus, absence of a hyperoccipital carina, and a femoral depression without coarse rugae throughout. The rugae that are present in the femoral depression are located ventrally and are arched and parallel. This is a very useful diagnostic character for the species, although the rugae are fainter in smaller specimens. Trissolcus aloysiisabaudiae from East Africa shares with T. comperei this sculptural pattern of the femoral depression and is a very similar species, excluding the sculpture of the mesonotum and the presence of a robust longitudinal mesoscutellar carina. These two species should certainly be compared in a greater context of African species.

Comments

Specimens from China have bright yellow legs and non-claval flagellomeres. Specimens from Japan have darker legs and flagellomeres. The pattern of macrosculpture on the frons and the coloration of the legs and antennae are essentially identical to the pattern found in T. semistriatus: specimens from higher latitudes tend to be darker with more robust facial sculpture.

Diagnosis

Trissolcus corai belongs to the cluster of species of the flavipes group with 4 clypeal setae, which includes T. japonicus, T. kozlovi, and T. plautiae. It can be separated from all of these by the transverse sculpture on the frons and by the distinctly smaller size of the lateral clypeal setae relative to the median pair. The number of clypeal setae is the best character for separating T. corai from T. vindicius, which can be very similar, particularly because the rugae on the frons of some T. corai may be weakly developed. In most T. corai, the mesoscutum between the notauli has longitudinal rugae, which will separate T. corai from T. japonicus, T. kozlovi, T. plautiae, and T. vindicius.

Etymology

This species is named for Joe Cora, former database manager at The Ohio State University, for his multitudinous contributions to the development of cybertaxonomic tools and the bioinformatics of Platygastroidea.

Diagnosis

Trissolcus edessae is unique among the species of the flavipes group treated here in that it has a medial mesoscutal carina. It bears no particular affinity to other Palearctic species in the flavipes group, but is morphologically similar to two species in the Nearctic: T. brochymenae and T. euschisti, from which it may be separated by the distinctly bicolored antennae, with A1–A6 yellow, and A7–A11 brown (Figures 46, 47). The labrum of T. edessae has a pair of distinct pits that are easily visible with light microscopy (Figure 50), whereas these pits in other species typically require scanning electron microscopy for observation. This character has yet to be fully explored throughout the genus because the labrum is often occluded, but we suspect that it will be informative.

Comments

The specimen illustrated in Figures 46–51 is the only known representative of T. edessae outside of the Nearctic. We compared this specimen directly to the type of T. edessae and found nothing to suggest that it is a different species. The collecting locality of Valencia, Spain, is noteworthy given the large volume of shipping traffic that passes through this port city and we consider it likely that T. edessae was delivered to Valencia on cargo. Determination of whether or not it became established in Europe will require focused sampling, as even in the Nearctic it is not a very common species. This phenonenon of species spreading around the world, as is the case with T. edessae and T. japonicus (Talamas et al. 2015), emphasizes the importance of a cosmopolitan perspective when conducting alpha taxonomy.

Diagnosis

Among Palearctic species, Trissolcus elasmuchae is most similar to T. semistriatus with which it shares a great deal of variability in the sculpture of the frons (compare Figures 54–55 to figures 172–177). Trissolcus elasmuchae can readily be separated from T. semistriatus by numerous characters: the episternal foveae in T. semistriatus are distinctly separate from both the mesopleural pit and the dorsal limit of the posacetabular sulcus whereas in T. elasmuchae the episternal foveae are more numerous and form a continuous line from the postacetabular sulcus to the mesopleural pit; the paracoxal sulcus in the ventral half of the metapleuron is indicated by deep cells in T. elasmuchae, and indicated in T. semistriatus at most as spaces between rugae that radiate from the anterior margin of the metapleuron to the metapleural pit. This form of the paracoxal sulcus is found in a few species of Trissolcus in the New World, T. zakotos, T. radix, and T. solocis, but is not known to us from any other Palearctic species. Trissolcus elasmuchae also has the metapleural epicoxal sulcus indicated by deep cells, which is atypical for the Palearctic fauna.

Comments

With T. davatchii and T. monirus treated as junior synonyms, T. elasmuchae takes on a curious distribution, at least as far as we have documented it, with specimens from Japan, South Korea, India, Vietnam and Europe, reaching as far West as England. However, this distribution is consistent with a pattern that we see in the distributions of other species of Trissolcus. Trissolcus flavipes, for example, is known from Sweden, England, the Asian Far East, and SE Asia.

Diagnosis

The transversely arched rugae on the frons ally this species with T. cultratus, with which it shares a poorly defined orbital furrow at its intersection with the malar sulcus. However, it is unlikely to be confused with this species because the densely setose eyes of T. exerrandus separate it from other species of Palearctic Trissolcus. We interpret the mesopleuron to be devoid of episternal foveae: cells at the dorsal limit of the postacetabular sulcus are sometimes slightly larger, but predominantly are the same size as the cells of ventral portion of the sulcus. Faint rugulae are present where the episternal foveae are typically present, leading us to believe that they are simply not externally developed in T. exerrandus. The subacropleural sulcus, present in all other Palearctic specis of Trissolcus, is conspicuously absent in T. exerrandus.

Diagnosis

Trissolcus flavipes can be easily identified by the circular impression on the frons directly above the antennal scrobe. Transverse striation may exist surrounding this impression to varying degrees but even in these cases the circular marking remains distinct. The lack of a well-defined orbital furrow near the malar sulcus, the presence of only 2 clypeal setae, and the visible dorsal limit to the cells inside of the axillar crescent (Figure 9) also help to identify this species from other members of the flavipes species group.

Comments

Trissolcus flavipes has a peculiar distribution, the specimens that we examined directly are from Europe, Eastern Asia, and Thailand and among them we found no characters that suggested a European species and an Asian species. Kononova (2014) published a photograph of the frons of T. crassus that illustrates the circular marking that we have found to be diagnostic for the species. Her description of T. crassus is entirely consistent with our concept of the species, and it is on this basis that we treat T. crassus as a junior synonym of T. flavipes. The two Ukrainian specimens from which she described T. crassus serve to help bridge the distributional gap between the opposite ends of the Palearctic. Notable intraspecific variation occurs in the degree to which microsculpture is expressed in the femoral depression, ranging from distinctly microsculptured throughout to entirely smooth.

Diagnosis

Trissolcus hyalinipennis is most similar to T. oobius, with which it shares a 4-merous clava. They may be separated by wing venation: the postmarginal vein is shorter than the stigmal vein in T. oobius and approximately twice as along as the stigmal vein in T. hyalinipennis (compare Figure 79 to Figures 124–127). Apart from this character, we found no other means of separating these two species.

Comments

Our determination of these specimens is based on their consistency with the description of Subba Rao and Chacko (1961). Many of our specimens were reared from the eggs of Bagrada hilaris (=Bagrada cruciferarum) (subsequently reared on eggs of Podisus maculiventris Say), which is also consistent with the biology presented in the original description. The holotype of this species is now considered to be lost (Rajmohana Keloth, personal communication), and thus designation of a neotype is needed to fully stabilize the name. We refrain from doing so because the reared specimens that we have on hand were collected in Pakistan, sufficiently far from New Delhi to not be considered from the same area, and the specimen from New Delhi that we do have is a male.

Diagnosis

Trissolcus japonicus is very similar to T. plautiae and T. kozlovi. Trissolcus japonicus can be separated from T. plautiae by the sculpture directly below the median ocellus: in T. japonicus this area is covered with microsculpture and often a dorsoventral furrow is present. In T. plautiae this area is entirely smooth and without microsculpture. Matsou et al. (2013) used the presence of a sublateral setae to separate T. japonicus from T. plautiae. However, in our experience with specimens reared in quarantine, sublateral setae are not uncommon in T. japonicus. Our preliminary analysis of molecular data is based on DNA extracted non-destructively from specimens of T. japonicus collected in China, Japan, and South Korea, and specimens of T. plautiae from China and Japan. In the specimens used for this analysis, and in the specimens used for monographic work, we found that the pattern of sculpture below the anterior ocellus is stable in both species. It is on this basis that we use this character to separate T. plautiae and T. japonicus, which is consistent with the findings of Matsuo et al. (2013).

Trissolcus japonicus and T. kozlovi can be separated by the sculpture of the frons directly above the antennal scrobe and sculpture of the mesoscutum between the notauli. The sculpture of the frons above the antennal scrobe in T. kozlovi is irregular whereas in T. japonicus, this area of the frons is either smooth or with weakly developed transverse lines of sculpture. The posteromedial mesoscutum in T. kozlovi is obliquely striate, with the lines of sculpture extending anterolaterally from the midline. In T. japonicus there is no macrosculpture in the posterior half of the mesoscutum.

The characters used to separate T. japonicus and T. kozlovi are based on examination of a small number of specimens of the latter species, and they are so similar that we considered that they may actually represent variation within a single species. However, because we are still able to consistently separate them based on morphology, we consider it best to continue to treat them as separate species. Analysis of the DNA sequence and biology of T. kozlovi should be a priority in the future, particularly because as BSMB spreads eastward in Europe its distribution is likely to overlap with that of T. kozlovi.

Comments

Trissolcus cercus, which we here treat as a junior synonym, was collected in western Russia, far from the distribution of what we otherwise know to be the native range of T. japonicus. In the late 1960s, Podisus maculiventris, which is a known host of Trissolcus japonicus, was introduced into Eastern Europe in the late 1960’s as a biological control agent (Schaefer & Panizzi 2000). The eggs associated with the holotype of T. cercus are included on the pin, and their morphology is consistent with that of eggs of P. maculiventris. The presence of T. japonicus in Eastern Europe may be the result of an adventive population of T. japonicus that followed the introduction of P. maculiventris, and then declined along with the stink bug population.

Material examined

Holotype, female, T. Kozlovi: RUSSIA: Voronezh Reg., Ramon’, 13.VIII.1972, V. Rjachovskij, ZMAS 0147 (deposited in ZIN). Paratypes: RUSSIA: 3 females, USNMENT00916623–00916625 (ZIN). Other material: MOLDOVA: 3 females, USNMENT00916620–00916622 (ZIN).

Diagnosis

Trissolus kozlovi is a difficult species to treat taxonomically because it is represented by a small number of specimens that are extremely similar to T. japonicus and T. plautiae. It remains diagnosable among the specimens at hand by subtle, but seeming reliable characters: from both T. japonicus and T. plautiae it may be separated by the obliquely oriented sculpture on the posterior mesoscutum between the notauli. The sculpture on the frons above the interantennal process is also useful for separating T. kozlovi from these species: in T. kozlovi the frons has irregular lines of sculpture; in T. plautiae this part of the frons is entirely smooth and in T. japonicus it is covered with microsculpture, sometimes with weak transvere striation or a dorsoventral furrow below the median ocellus. Assessment of this character’s utility for species-level identification requires additional specimens and, if possible, corroboration with molecular data.

Comments

In most specimens, including the holotype, there are 4 clypeal setae present. The lateral setae are about half the length of the median pair, and in some specimens the lateral setae appear to be absent. In some cases a seta is absent from one side only, in some, the lateral setae are appressed to the labrum or clypeus, probably as a preservation artifact, in others neither are evident. We suspect that these setae are broken off, but because we cannot be certain, the description for this character is coded as having both 2 and 4 setae.

Diagnosis

Trissolcus larides is unique among species with a setose metapleuron in that the episternal foveae are entirely absent. It is most similar to T. levicaudus with which it shares an antero-posteriorly compact habitus, the absence of notauli, a smooth speculum, and T1 smooth posterior to the basal costae. The two may be separated by a number of characters: the anteromedial portion of T2 is striate in T. larides and smooth in T. levicaudus; the mesoscutal humeral and mesoscutal suprahumeral sulci are smooth furrows in T. larides and comprised of cells in T. levicaudus; T. levicaudus has a single episternal fovea and T. larides has none; the prespecular sulcus extends ventrally to the mesopleural pit in T. levicaudus but not in T. larides; the cells along the anterior margin of the metascutellum are deep punctures in T. levicaudus and in T. larides this sulcus is a furrow with broad interspaces between crenulae; the wing membrane at the junction of the marginal, postmarginal, and stigmal veins is pigmented in T. larides and hyaline in T. levicaudus.

Diagnosis

The coarse sculpture found throughout the femoral depression (Figure 99) distinguishes T. latisulcus from other Palearctic species in the genus. The femoral depression in T. comperei and T. carinifrons has parallel arched rugae (Figures 27, 28) but these are limited to the ventral portion of this area. The anterior margin of the mesoscutellum often is distinctly raised, creating the appearance of an enlarged scutoscutellar sulcus (Figure 101), which is also useful for identifying this species.

Comments

We observe significant size variation in this species, suggesting that it is a generalist attacking eggs of a variety of sizes, and perhaps this contributes to the expansive distribution of Trissolcus latisulcus from eastern Australia to India.

Diagnosis

Trissolcus levicaudus is closest morphologically to T. larides, with which it shares a setose posterior metapleuron, absence of notauli, a smooth speculum, and T1 without striae posterior to the cells along the anterior margin. It may be separated from T. larides by the absence of striation on T2, a metapostnotum extending to the lateral margin of the metascutellum in dorsal view, and the entirely hyaline fore wing.

Etymology

The species epithet “levicaudus”, meaning “without knots” or “smooth” refers to the smoothness of the metasomal tergites.

Diagnosis

Among Palearctic species in the basalis group T. mitsukurii can be identified by the combination of the greatly enlarged antennae clava (A7–A11) in females (Figures 107, 109), the size of which is emphasized in comparison to the compressed A4–A6, an orbital furrow that is expanded at its intersection with the malar sulcus (Figures 109–111), and the line of setae along the dorsal margin of the first laterotergite (Figure 110). During the course of this revision we examined a number of species from southeast Asia that share the above-mentioned diagnostic characters, but to our knowledge the distributions of these species do not extend into temperate Asia.

Diagnosis

Trissolcus nycteridaner can be identified by the presence of a hyperoccipital carina, the undefined orbital furrow at the malar sulcus, the extremely slender mandibles, and the longitudinal sculpture on the mesoscutellum and posterior mesoscutum. It is similar to T. gonopsidis, but can be easily distinguished by the slender mandibles and absence of facial striae. Among species of the flavipes group, it is unusual in that the mesoscutal humeral sulcus is a mostly smooth furrow.

Etymology

The name of this species was inspired by young Luke Meladossi of Scarsdale, New York, who inquired if a species could be named for the superhero Batman. Like Batman, species of Trissolcus are dark in color, rarely seen by the public, kill bad guys (stink bugs) for the benefit of humankind, and are at times unfairly vilified on the basis of their name (parasitic wasp). The epithet derives from the Greek words “nycteris,” meaning “bat”, and “aner,” meaning “man”, and is treated as a noun in apposition.

Diagnosis

Trissolcus oobius shares with T. hyalinipennis a 4-merous antennal clava in females. This character, in combination with a postmarginal vein that is shorter than the stigmal vein, unambiguously seperates it from all Palearctic species. Kozlov described numerous species based on small differences in the length of the postmarginal vein, and we here treat most of them as as junior synonyms. The length of the postmarginal vein varies from nearly absent to approaching the length of the stigmal vein in a continuous gradient such that separation based on arbitrary lengths is not useful for species identification (see Figures 124–127).

Comments

The degree to which longitudinal rugae extend from the basal costae of T1 is variable, ranging from essentially absent to distinctly present. Similarly, anterior T1 may be faintly striate or entirely smooth. Microsculpture on the mesoscutellum varies from present throughout to absent, and in some specimens the microsculpture is only present laterally. Specimens in the type series of T. oobius are larger than the specimens in the type series of species here treated as junior synonyms. These larger specimens have coarser sculpture on the frons and a distinct preocellar pit. In the smallest specimens the preocellar pit is absent and in specimens of intermediary size the pit is absent or very small.

Diagnosis

Trissolcus perepelovi can be distinguished by the distinctly bulging ventral mesopleuron, the absence of episternal foveae, striation on T2 that is limited to the anteromedial portion of the tergite, and the smooth area on the frons between the antennal scrobe and the median ocellus. Variability occurs in the extent to which the microsculpture on the frons is effaced. In the paratypes of T. deserticola and T. dircus that we examined, the area does not extend to the inner margins of the compound eyes, whereas in the type series of T. perepelovi it may either extend to the margin of the compound eye or be separated by a patch of microsculpture. The expanded smooth area in the type series of T. perepelovi corresponds to a reduction in surface sculpture of the gena and reduction in the size of the genal carina, which are much more pronounced in the paratypes of T. deserticola and T. dircus. As in many other species of Trissolcus, the color of the antennal segments preceding the clava is not stable and A3–A6 vary from yellow to brown. Similar to T. semistriatus and T. comperei, the extent to which the striae of the antennal scrobe extend onto the ventral frons is variable within this species. The paratype of T. dircus shows definitive striation on the ventral frons, whereas this striation is very weak in the type series of T. perepelovi and absent in the paratype of T. deserticola.

Diagnosis

Trissolcus rufiventris is usually easily identifiable by the color of the metasoma, which in some cases is bright yellowish-orange in color. This color pattern is not known to us from other species and thus can be used effectively to confirm the identity of this species. However, the metasoma may be dark brown, approaching black, and thus color should not be used to exclude specimens from this species. Although it is less accessible, the most reliable character for T. rufiventris is the presence of a single basiconic sensillum on A7. All other species of Palearctic Trissolcus have either 2 basiconic sensilla on A7 or none.

Diagnosis

Setation on the first laterotergite unambiguously separates T. saakowi from all Palearctic species in the flavipes group. This character occurs in T. stoicus, T. mitsukurii, and rarely in T. semistriatus, all of which are quite different species in terms of their diagnostic characters and general appearance. Most similar to T. saakowi in the Palearctic is T. tumidus, with which it shares the punctate-rugulose interior of the axillar crescent (Figures 8, 11). Trissolcus saakowi may be separated from T. tumidus by setation of the first laterotergite and the absence of a well defined orbital furrow at its intersection with the malar sulcus. These two species have similar distributions, stretching from the the Middle East to Far Eastern Asia.

Comments

Trissolcus saakowi exhibits variability in the sculpture of the mesonotum and the punctation and sculpture of the frons lateral to the antennal scrobe. The mesoscutum may be longitudinally striate throughout, reticulate anteriorly with longitudinal lines medially or posteriorly, or there may be no pronounced macrosculpture at all. The notaulus is typically very short, but may be indistinguishable from mesoscutal striation or even entirely absent. The holotype of T. mentha is smaller than most specimens of T. saakowi, which we attribute to development in a smaller host egg. It also exhibits less pronounced surface sculpture than the larger specimens of T. saakowi and the notauli are absent. Female specimens from Pakistan and China have dense punctation on the lateral frons and striation that extends laterally from the antennal scrobe onto the ventrolateral frons. Two males from Pakistan have label data identical to that of the females, and have the sparse punctation and absence of macrosculpture on the frons as do males from other regions.

Lectotype designation

The specimen selected by Kozlov as the lectotype of T. simoni (NHMW 0004) was sent to Mayr by A. Saakow in 1901 according to Mayr (1903). Because this specimen was not part of the original type series it is ineligible to be designated as a lectotype. Szabó (1975) designated a lectotype from Mayr’s syntype series, but did not indicate which of the three specimens on the pin was meant to be the lectotype. To stabilize the nomenclature, we here select one of these specimens (USNMENT01029022b, deposited in NHMW) as the lectotype.

Comments

Examination of specimens across a wide geographical range revealed that the characters used by previous authors to separate T. volgensis and T. scutellaris, (and T. ghorfii from T. histani) are variable. The microsculpture of the mesoscutellum varies from distinctly present throughout to entirely absent (Figures 164–167). Mesoscutal characters are similarly variable: posteromedial striation, a median mesoscutal carina, and raised rugulose sculpture vary along a continuous gradient from absent to moderately pronounced (Figures 164–167). Kozlov’s 1968 key to Palearctic Trissolcus used the distance between the notauli (referred to as parapsidal grooves) to separate T. ghorfii and T. histani, specifically that the distance between the notauli (measured posteriorly) is more than twice the length of the notauli in the latter species. We examined a series of T. histani that was compared to the holotype and determined by Voegele, and in none of these specimens is this the case. The sculpture of the dorsal frons was not mentioned in the most recent keys by Kononova (2013), Petrov (2013) and Kozlov & Kononova (1983). Were it not for a continuous spectrum of variation, the sculptural development of the frons might separate T. vassilliewi from T. scutellaris. We present a plate of images (Figs 158–163) that illustrate the variation that occurs within this species, even within Mayr’s type series of T. simoni. In the lectotype of T. vassilliewi the frons outside of the antennal scrobe has microsculpture but is otherwise smooth (as in Figure 158). In other specimens, smooth shallow punctures are present along the inner orbits (Fig. 160) or across the dorsal frons (Fig. 161). The punctures may be surrounded by slightly raised rugulae, or, as in the lectotypes of T. simoni and T. volgensis, the rugae are coarse (Figures 162–163). Similarly, the degree of transverse striation directly above the antennal scrobe varies from absent to pronounced. Other structures that vary within this species are the epomial carina, which is always present, but may be robustly or weakly indicated, and the median mesoscutal carina, which is either absent or weakly indicated.

Diagnosis

Trissolcus semistriatus is most similar to T. basalis from which it can be separated by the complete netrion sulcus, distinct and regular cells of the postacetabular sulcus and, in most cases, by the distinct cells of the mesoscutal humeral sulcus (always indicated by a smooth furrow in T. basalis and very rarely so in T. semistriatus). It is also similar to T. elasmuchae from which it can be separated by the absence of a well defined paracoxal sulcus in the ventral portion of the metapleuron.

Comments

The immense geographical distribution of Trissolcus semistriatus, in combination with its capacity for variation in size, color, and surface sculpture (Figures 172–183) have resulted in numerous redescriptions of this species. It is by examining specimens across the Palearctic land mass that we have been able to document intermediate forms that connect phenotypes previously treated as discreet. The general trend is that specimens from higher latitudes tend to be larger, darker, and have more robust sculpture on the frons. The sculpture on the frons in Trissolcus semistriatus, T. basalis and T. elasmuchae have similar patterns when rugae are present and they share the same spectrum of sculptural development, varying from coarsely rugose to absent. Preliminary results on a study of phenotypic plasticity in Trissolcus indicate that color and size are directly influenced by temperature and host species. Species with distributions as large as T. semistriatus, T. basalis, and T. elasmuchae are likely to be oligophagous or polyphagous, increasing the degree of phenotypic variation that can occur.

Diagnosis

Trissolcus stoicus can be distinguished from most species treated here by having 6 clypeal setae and a complete hyperoccipital carina, a combination which is otherwise known to us only from T. carinifrons. These are otherwise dissimilar species and can be separated by the sculpture of the gena (coarse in T. carinifrons and smooth in T. stoicus) and the shape of the foveae that form the mesepimeral sulcus (circular in T. carinifrons and elongate in T. stoicus). The form of the metanotal trough, in which the cells are present at the bottom of a narrow furrow is shared with T. exerrandus, from which it may separated by the presence of dense setation on the eyes in the latter. The distribution of striae on T2 in T. stoicus, in which striae are present laterally and absent medially, is unusual for Trissolcus, at least in our experience. However, this character is not fully visible in the holotype specimen and we are thus hesitant to use it for identification with a sample size of only three specimens, particularly when a wealth of other characters exists to identify this species.

Lectotype designation

We here designate specimen B.M. TYPE HYM. 9.314 (deposited in BMNH) to be the lectotype of this species.

Comments

Trissolcus stoicus exhibits two characters that suggest in may be an intermediate form between the flavipes and thyantae species groups. The hyperoccipital carina and setation of the first laterotergite ally it with the flavipes group. However, the presence of 6 clypeal setae and 2 large setae in the posteroventral metapleuron suggest relation to the thyantae group.

Diagnosis

Trissolcus tersus can be identified by the line of foveae along the dorsal margin of the mesopleural carina (Figures 189, 192), a character known to us so only from this species. The setation of the posteroventral metapleuron (Figure 189) and the presence of facial and malar striae (Figure 193) are also useful for its identification.

Diagnosis

Trissolcus tumidus is unusual among Palearctic species in the flavipes group because the episternal foveae are clearly separated from the cells of the postacetabular sulcus and the mesopleural pit, a character shared with T. gonopsidis and T. nycteridaner. In most species of the flavipes group these foveae form a more or less continuous line between the postacetabular sulcus and the mesopleural pit. This character, in combination with a glabrous first laterotergite and a well-defined and ventrally expanded orbital furrow, separate it from other species of the flavipes group.

Comments

Petrov (2013) used the longitudinal striation of the mesoscutum between the notauli and the smooth and shining frons between the antennal scrobe and median ocellus as identifying characters. In the lectotype of T. tumidus, longitudinal striation is present between the notauli but the frons is not entirely smooth and shining. Our examination reveals that both of these characters are size dependent. Large specimens tend to have longitudinal striation between the notauli, pustulate microsculpture throughout the mesoscutum (Figure 208), microsculpture throughout the frons (Figures 203, 205), and a gena that does not sharply recede behind the compound eye. Smaller specimens have less development of mesoscutal sculpture (Figures 206–207), the frons is smooth and shining (Figure 204), there is no striation between the notauli (Figure 206), and the gena recedes sharply behind the compound eye.

Diagnosis

Trissolcus vesta is likely to be one of the more difficult species to identify due to the subtlety of some of its diagnostic characters, specifically the posterior vertex and the setation in the ventral metapleuron. In addition to metapleuron setation it has the suite of characters that delimit the thyantae group: notauli, 6 clypeal setae, and well defined episternal foveae that extend from the mesopleural pit to the dorsal limit of the acetabular carina. In T. vesta the posterior vertex is medially depressed, creating a triangular area in dorsal view that serves as an important diagnostic character that was recognized by Kozlov (1978), but also one that is best interpreted in the context of other species. Of additional use are the mesoscutal humeral and suprahumeral sulci, which are comprised of smooth furrows or very small and irregular cells, contrasting the large cells found in the most similar Palearctic species, T. scutellaris.

Comments

The key to species of Palearctic Trissolcus by Kozlov (1978) used microsculpture of the mesoscutellum as a diagnostic character for this species. Contrary to his key, we observed that the sculpture of the mesoscutellum is significantly different from that of the mesoscutum: the mesoscutum is distinctly coriacieous throughout and microsculpture can be seen only very faintly on the posterior portion of the mesoscutellum under high magnification.

Diagnosis

T. viktorovi is a distinctive species that can be identified from other species of the thyantae group by the broad gena, the smooth furrow between the hyperoccipital carina and the dorsal and posterior margins of the compound eye. The median mesoscutal carina is distinct in T. viktorovi and is useful for confirming its identity, but this feature may also be found in other Palearctic species of the thyantae group.

Diagnosis

Trissolcus vindicius is delimited more by a unique combination of characters than by a single distinctive feature. It can be separated from other species in the flavipes group by the presence of 2 clypeal setae, a well-defined and ventrally expanded orbital furrow, episternal foveae that extend from the postacetabular sulcus to the mesopleural pit, and a mesoscutum without a median mesoscutal carina.

SOUTH KOREA: 5 females, USNMENT00896022–00896025, 00896148 (CNCI).

Comments

The two specimens from Nepal fit within our concept of T. vindicius, but exhibit some notable variation. They are much smaller, have broader mandibles, the microsculpture of the mesoscutum is slightly effaced posteriorly, and the occipital carina is finely crenulate and nearly smooth along its anterior margin. In one specimen the episternal foveae are fewer in number and dorsoventrally elongate relative to the roughly circular shape that is typical for T. vindicius, possibly an allometric consequence of its smaller size.

Diagnosis

Trissolcus yamagishi can be distinguished from other Palearctic Trissolcus in the basalis group by the complete mesopleural carina and the characteristic sculpture of the frons in which a dorsoventral carina below the anterior ocellus is flanked by areas of effaced microsculpture (Figures 222, 224). The characters used to separate T. yamagishii and T. comperei (=T. itoi) in the key to species by Ryu (1984) are not reliable. Variation occurs in the degree of rugosity in the mesoscutellum in both T. yamagishii and T. comperei, and the antennae and legs are subject to color variability. Specifically, the legs in T. yamagishii have two color forms, one in which the legs are entirely yellow beyond the coxae and one in which the trochanters and basal femora are brown, becoming lighter distally. We examined a single male of this species which had bright yellow legs beyond the coxae.

Paratype: SERBIA: 1 female, Hym.Typ.No. 4611, Mus.Budapest (HNHM).

Comments

This species clearly does not belong in Trissolcus and we place it in Phanuromyia Dodd sensu Taekul et al. (2013) based on the rugulose sculpture throughout T2 and the apparently 4-merous antennal clava. We were unable to assess the characters of the ventral frons, but given our confidence in transferring this species to Phanuromyia, we did not find it necessary to attempt dissolving the surrounding glue.

Comments

We transfer this species to Telenomus based on the 3-merous antennal clava and T2 that is wider than long. The sculptural details of the head are difficult to assess because of the state of the lectotype and paralectotype specimens. The visible characters, including the transverse rugae of the dorsal frons, place this species in the laricis species group of Telenomus sensu Johnson (1984b) and Huggert (1983).
