Description and mitochondrial genome sequencing of a new species of inquiline gall wasp, Synergus nanlingensis (Hymenoptera, Cynipidae, Synergini), from China https://jhr.pensoft.net/article/119433/ Journal of Hymenoptera Research 97: 105-126

DOI: 10.3897/jhr.97.119433

Authors: Yu-Bo Duan, Yan-Jie Wang, Dao-Hong Zhu, Yang Zeng, Xiu-Dan Wang

Abstract: A new species of inquiline gall wasp, Synergus nanlingensis Wang & Zeng, sp. nov., which was reared from galls on Castanopsis eyrei Tutch (Fagaceae) collected in Guangdong Province, China, is described and illustrated herein along with its mitochondrial genome. The mitogenome of S. nanlingensis is 16,604 base pairs in length and comprises 37 genes, which is typical of mitogenomes. One large control region was detected in the S. nanlingensis mitogenome, which differed from that reported for other Cynipidae species. Similar to other Cynipidae species, S. nanlingensis has the same four common gene rearrangement events; however, it shows some differences, as follows: trnS1 is downstream of Cytb; trnS2 is upstream of nad1; and trnC is downstream of rrnS. Phylogenetic analysis using COI, CytB, and 28S-D2 sequences confirmed that S. nanlingensis is a distinct species belonging to the genus Synergus Hartig.

Male-biased night foraging by bumblebees (Hymenoptera, Apidae, Bombus spp.) in Taiwan https://jhr.pensoft.net/article/113486/ Journal of Hymenoptera Research 96: 949-954

DOI: 10.3897/jhr.96.113486

Authors: Yun-Chen Hsieh, Joe Chun-Chia Huang, Wen-Chi Yeh, Chun-Yang Tsai, Chien-Jung Lin, Sheng-Shan Lu

Abstract: Known nocturnal behaviors of bees in the superfamily Apoidea, including the genus Bombus, were almost exclusively of females. Here we report observations of active free-ranging male Bombus at night in the plant nursery of the Fushan Research Center, Taiwan, in April 2022. Nectar feeding by males at inflorescences was confirmed by tongue-licking in the absence of pollen collecting. The numbers of active female and male bumblebees during the daytime were close to equal. In contrast, only males were found to be active in the night. Our observations suggest that such nocturnal activity is facultative. This finding not only provides a rare case of nocturnal activity in free-ranging Bombus, but also demonstrates that such behaviors can vary between the sexes.

At the dawn of megadiversity – Protoitidae, a new family of Chalcidoidea (Hymenoptera) from Lower Cretaceous Lebanese amber https://jhr.pensoft.net/article/105494/ Journal of Hymenoptera Research 96: 879-924

DOI: 10.3897/jhr.96.105494

Authors: Jonah M. UImer, Petr Janšta, Dany Azar, Lars Krogmann

Abstract: The earliest representatives of Chalcidoidea are described from Barremian age Early Cretaceous Lebanese amber and classified in Protoitidae Ulmer & Krogmann, fam. nov. (Hymenoptera: Chalcidoidea). Protoitidae exhibits a high morphological diversity of the terminal metasomal tergum which may indicate a broad spectrum of oviposition capabilities and the ability to occupy a diverse range of ecological niches. Protoitidae comprises two genera, Protoita Ulmer & Krogmann, gen. nov., and Cretaxenomerus Nel & Azar, 2005 based on C. jankotejai Nel & Azar, 2005, which is transferred from Scelionidae (Hymenoptera: Platygastroidea) to Protoitidae. Together, 10 new species, all by Ulmer and Krogmann, are described in the two included genera–Protoita bidentata, P. istvani, P. noyesi, P. petersi, Cretaxenomerus brevis, C. curvus, C. deangelis, C. mirari, C. tenuipenna, and C. vitreus. Keys to the genera and species of Protoitidae are provided. In addition, we examine the postulated plesiomorphies and apomorphies within Chalcidoidea with respect to the fossil record, and provide additional hypotheses on their biogeographic origins.

New suggestion of the species group reconstruction of genus Nomada Scopoli, 1770 (Hymenoptera, Apidae) from Korea https://jhr.pensoft.net/article/106452/ Journal of Hymenoptera Research 96: 805-816

DOI: 10.3897/jhr.96.106452

Authors: Kayun Lim, Seunghwan Lee

Abstract: Genus Nomada, which includes approximately 800 species, is the largest genus in the subfamily Nomadinae and the sole genus in the tribe Nomadini. Its taxonomic classification is particularly challenging due to high morphological variations, making it one of the most controversial groups in the subfamily. In order to shed light on the complex classification of Nomada species and their tribal position, this study conducted a multi-locus phylogeny using one mitochondrial gene (COI) and five nuclear protein-coding genes (EF1α, Nak, Opsin, Pol Ⅱ, Wingless). The study focused on expanding the knowledge of some East Palearctic species, with the ultimate goal of reviewing species groups of Nomada present in Korea. In this study, we suggest that the ruficornis species group is polyphyletic. Some species should be moved to more appropriate species groups as follows: N. tsunekiana, N. emarginata, and N. flavopicta into the basalis species group; N. aswensis, N. kaguya, and N. taicho into the armata species group.

Abstract: The first record of the Darwin wasp, Cyrtorhyssa moellerii Bingham, 1898 (Hymenoptera, Ichneumonoidea, Rhyssinae) from Thailand is presented. Members of both sexes are fully described and illustrated. The biology of C. moellerii, a parasitoid of the pleasing fungus beetle Encaustes opaca Crotch, 1876 (Coleoptera, Erotylidae), is reported for the first time. Hosts were associated with standing deadwood of Anthoshorea henryana (Pierre ex Laness.) P. S. Ashton & J. Heck (Dipterocarpaceae) in dry evergreen forest, Nakhon Ratchasima province, northeastern Thailand. DNA barcodes (cytochrome c oxidase subunit 1 sequence (COI)) were generated for both host and parasitoid and phylogenetic trees constructed for these and other members of the same family and subfamily respectively. A key is provided to separate the three known species of Cyrtorhyssa. This is the first confirmed host record for a tropical species of Rhyssinae as well as the first from Erotylidae.

An alternative host searching strategy found in the subfamily Hybrizontinae (Hymenoptera, Ichneumonidae) https://jhr.pensoft.net/article/106836/ Journal of Hymenoptera Research 96: 629-639

DOI: 10.3897/jhr.96.106836

Authors: Yu Hisasue, Kazuhiko Konishi, Kenji Takashino

Abstract: The present study reports the oviposition behavior of the ant parasitoid wasp, Ghilaromma orientalis, on an undescribed ant species from Lasius fuliginosus species group in Japan, illustrated by clear photographs. Previously, the oviposition behavior in the subfamily Hybrizontinae had been limited to species hovering on an ant trail and attacking larvae carried by worker ants. In contrast, in G. orientalis, whose oviposition behavior had not been reported to date, the wasp hung on the grass growing along the ants’ trail by its hind legs with its head down, and when workers with larvae pass by, directed its abdomen toward the larvae with its hind legs remaining on the grass. Our findings suggest that the subfamily Hybrizontinae employs two host-searching strategies—an active strategy previously known and the ambush-type host-searching strategy employed by G. orientalis. The ambush-type strategy affords G. orientalis the advantage of laying eggs in a narrow environment where wasps cannot fly without being noticed by ants. Moreover, by avoiding detection through ambush tactics, wasps are increasing their chance for attack, as ants continue to transport their larvae. However, the search range of wasps is reduced, which may limit the opportunities for parasitization. Additionally, while Lasius nipponensis has been observed as the sole known host of G. orientalis, the oviposition behavior has now been observed in an undescribed species of L. fuliginosus group, suggesting that G. orientalis may have a subgenus-specific host range.

Inquiline insects of the honey bee Apis mellifera in Western Siberia (Hymenoptera, Apidae) https://jhr.pensoft.net/article/104720/ Journal of Hymenoptera Research 96: 555-568

DOI: 10.3897/jhr.96.104720

Authors: Victoria V. Stolbova, Vitaly A. Stolbov

Abstract: The multi-species associations of insects (symbiocenosis) in honey bee hives currently include more than 15 orders of Insecta. We present the results of studying the inquilines of bee hives in the south of Western Siberia. In the honeybee hives of this region 37 insect species from 8 orders (Dermaptera, Thysanoptera, Psocoptera, Hemiptera, Coleoptera, Hymenoptera, Lepidoptera, Diptera) were identified. Inquiline insects were observed in 77% of hives in 81.5% of the studied apiaries. Coleoptera prevailed among the orders, accounting for 94% of observations. The overall eudominant was Cryptophagus scanicus (Linnaeus, 1758) (87.8%); the subdominants were Dermestes lardarius Linnaeus, 1758 and Contacyphon variabilis (Thunberg, 1787). The smallest number of insect species can be attributed to specific groups. These are C. scanicus, a detritophage that primarily feeds on mold fungi hyphae, but can also consume bee supplies; and Galleria melonella (Linnaeus, 1758), a widespread pest of bee colonies, that feeds on bee bread, honey, wax and bee brood. The facultative group includes detritophages, pollen- and honey-feeding species, that find suitable conditions for feeding and developing in beehives (Vespidae, Formicidae, etc.). Representatives of accidental group were the most diverse in species composition and type of nutrition but they were always individually found in hives. In total, 42 species of insects are currently recorded in the beehives of Western Siberia.

A taxonomic re-assessment of the widespread oriental bumblebee Bombus flavescens (Hymenoptera, Apidae) https://jhr.pensoft.net/article/104715/ Journal of Hymenoptera Research 96: 507-541

DOI: 10.3897/jhr.96.104715

Authors: Chawatat Thanoosing, Michael C. Orr, Natapot Warrit, Alfried P. Vogler, Paul H. Williams

Abstract: Bombus flavescens Smith is one of the most widespread bumblebee species in the Oriental region. Due to colour polymorphisms, this species or species-complex has been a challenge for taxonomy. This study aims to assess the taxonomic status of the flavescens-complex using evidence from COI barcodes and morphology. We then reconstruct its biogeographic history from a phylogenetic analysis of populations across the current range, combining COI with 16S and nuclear PEPCK data. Despite a large range of polymorphisms across its distribution, the results show that B. flavescens is a single species based on algorithmic species delimitation methods, and it is clearly separated from its sister species, B. rotundiceps Friese. We suggest that B. flavescens diverged from its sister lineage in the Himalaya and dispersed into Southeast Asia in the Pleistocene. Conservation of the widespread B. flavescens will need to consider its several unique island populations.

Genetic variation and phylogenetic relationships of commercial populations of Bombus ignitus (Hymenoptera, Apidae) with wild populations in Eastern Asia https://jhr.pensoft.net/article/102569/ Journal of Hymenoptera Research 96: 495-506

DOI: 10.3897/jhr.96.102569

Authors: Saeed Mohamadzade Namin, Jiaxing Huang, Jiandong An, Chuleui Jung

Abstract: The bumblebee, Bombus ignitus (Hymenoptera, Apidae), plays a vital role in pollination in Northeast Asia, including Korea, China, Japan, and Far East Russia. Understanding the genetic makeup of the population can aid in its conservation. This study explores the DNA barcode region of cytochrome C oxidase subunit I (COI) of B. ignitus in commercial populations from Korea and Japan. The results reveal low intraspecific genetic diversity among commercially reared populations, with a maximum sequence divergence of 0.3%. Analysis of a 458-bp region of the COI gene, including 384 previously reported sequences, identified 20 haplotypes with the highest sequence divergence of 2.01% in East Asia. Commercial populations show a genetic similarity primarily with the Japanese population. Cross-mating with native populations could result in competition and genetic contamination, leading to reduced fitness and sensitivity to future environmental conditions. Morphological similarities make monitoring of such effects challenging. This study provides a basis for further research on population studies, conservation, and commercialization of local populations of B. ignitus for better pollination services while minimizing risks of reducing genetic diversity and increasing competition between native and introduced populations.

Taxonomy of the genus Peucobius Townes (Hymenoptera, Ichneumonidae, Sisyrostolinae) https://jhr.pensoft.net/article/98222/ Journal of Hymenoptera Research 95: 245-260

DOI: 10.3897/jhr.95.98222

Authors: Andrey I. Khalaim, Enrique Ruíz-Cancino, Juana Maria Coronado-Blanco

Abstract: The genus Peucobius Townes previously comprised two species occurring in the Nearctic region: P. fulvus Townes and P. piceus Townes. In the current study we revise this genus, transfer it to the subfamily Sisyrostolinae (comb. nov.), and describe two new species – P. bennetti Khalaim & Ruíz-Cancino, sp. nov. from Central Mexico and P. shimizui Khalaim, sp. nov. from Japan. The genus Lygurus Kasparyan occurring in Russian Far East and Taiwan is morphologically similar to Peucobius; characters for distinguishing these two genera are provided for the first time with the use of colour photographs. Identification keys to four world species of Peucobius, and to species of Lygurus and Peucobius occurring in the East Palaearctic region, are provided. We suggest that species of Peucobius are associated with xyelid sawflies (Xyelidae) whose larvae feed in staminate pine cones.

Genetic evidence for parthenogenesis in the small carpenter bee Ceratina dallatoreana (Apidae, Ceratinini) in its native distribution range https://jhr.pensoft.net/article/87165/ Journal of Hymenoptera Research 95: 199-213

DOI: 10.3897/jhr.95.87165

Authors: Michael Mikát, Jakub Straka

Abstract: Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop from fertilized eggs, whereas haploid males originate from unfertilized eggs. However, some taxa of Hymenoptera have evolved thelytoky, in which diploid females originate parthenogenetically from unfertilized diploid eggs. In contrast to some other hymenopteran lineages, like ants and parasitic wasps, thelytoky is generally very rare in bees. Here, we evaluated the frequency of thelytoky in the small carpenter bee Ceratina dallatoreana, which was previously assumed to be thelytokous. By comparing genotypes of microsatellite loci between mothers and their offspring, we found that all female offspring were genetically identical to their mothers. We conclude that parthenogenesis is the prevailing and perhaps obligate mode of reproduction in C. dallatoreana. We also classify the cytological mode of this parthenogenesis as apomixis, or automictic parthenogenesis with central fusion and extremely reduced or non-existing recombination, because offspring showed no decrease of heterozygosity. Because sociality is influenced by relatedness and Ceratina are ancestrally facultatively social, the high relatedness afforded by parthenogenesis should associate with social living in the nest. In accordance with previous work, however, we found no social nests of C. dallatoreana.

Oviposition experience promotes active reproductive behaviour in a synovigenic parasitoid https://jhr.pensoft.net/article/96631/ Journal of Hymenoptera Research 95: 1-12

DOI: 10.3897/jhr.95.96631

Authors: Zi-Yin Wang, Yu-Fan Wang, Si-Yu Yin, Peng-Cheng Liu, Hao-Yuan Hu

Abstract: Parasitoids are important insects that are commonly released into the environment to reduce the population sizes of pest species. The lifetime reproductive success of parasitoids mainly depends on host availability and the availability of mature eggs. Consequently, it is predicted that female wasps must balance the risk of egg or host (time) limitation with maximized lifetime fecundity. Typically, synovigenic females, which continue to mature eggs throughout their lifetime, have been shown to adjust their egg production rate in response to environmental variations in host availability to reduce the risk of egg limitation. In this study, we found that in a synovigenic egg parasitoid, Anastatus japonicus (Hymenoptera: Eupelmidae), the oviposition experience of Ana. japonicus females significantly enhanced the egg load and increased the rate of mature egg production. However, in contrast to other studies, the experience of contact with a host did not significantly affect the egg load in females. This result suggests that the overall oviposition experience might induce an adjustment and accelerate egg maturation in Ana. japonicus and is likely more important in egg maturation than transitory host contract. In addition to affecting the egg load, oviposition experience influenced Ana. japonicus female reproductive behaviour, which shifted virgin female behavioural preferences from mating to oviposition and laying more eggs per clutch. Our study provides an optimal strategy for the post-oviposition release of Ana. japonicus, an egg parasitoid of several lepidopteran forest pests, to improve biocontrol effectiveness.

A remarkable new family of stinging wasps from the Cretaceous of Myanmar and China (Hymenoptera, Aculeata) https://jhr.pensoft.net/article/85613/ Journal of Hymenoptera Research 94: 163-190

DOI: 10.3897/jhr.94.85613

Authors: Anderson Lepeco, Diego N. Barbosa, Gabriel A. R. Melo

Abstract: Burmese amber provides a unique window to the Cretaceous entomofauna, being the most prolific source of fossil insects for the period. Presently, about 61% of the Hymenoptera described from amber deposits in Myanmar are stinging wasps (Aculeata), including eight families known solely from Burmese amber. In the present work we describe the aculeate family †Trifionychidae fam. nov., as well as three new genera: †Prionaspidion gen. nov., including †Prionaspidion brevidens sp. nov. and †P. nanus sp. nov.; †Trifionyx gen. nov., including †Trifionyx pilosus sp. nov.; and †Trifionyximus gen. nov., including †Trifionyximus cracens sp. nov. We also reinterpret the fossil genus †Mirabythus, described based on rock impressions from the Yixian formation in China and originally attributed to Scolebythidae. †Mirabythus is moved to the new family, based mainly on the characteristic mandible; the large clypeus with a series of small denticles on the apical margin; the frons protruding over lateral portions of clypeus, directing the antennal sockets downwards below ocular level; and the presence of nine flagellomeres. Based on resemblances with fossil impressions attributed to †Bethylonymidae, we tentatively include the new family within the superfamily †Bethylonymoidea. Discovery of †Trifionychidae fam. nov. adds a novel lineage to the pool of aculeate families from the Cretaceous which did not survive to the present day.

Abstract: Riptortus pedestris (Fab.) (Hemiptera, Alydidae) is one of the most damaging insects of leguminous crops in Eastern Asia but has only recently emerged as a pest in Bangladesh. Eggs, nymphs and adults of R. pedestris are here reported from mung bean (Vigna radiata (L.)) fields in Bangladesh. Two parasitoid species were reared from field-collected eggs of R. pedestris, the solitary Hadronotus pubescens (Motschoulsky) (Hymenoptera, Scelionidae) and a gregarious species of Ooencyrtus Ashmead (Hymenoptera, Encyrtidae). Here we redescribe H. pubescens, treat H. hogenakalensis (Sharma) as a junior synonym, and report aspects of its biology that were investigated under laboratory conditions. The number of eggs parasitized by H. pubescens was constant with eggs up to 48 hours in age, decreasing by 14% for 96 hour-old eggs. As host egg age increased, the parasitoid mean development time increased and the longevity of the parasitoids decreased.

Discovery of a new phragmotic species of the ant genus Carebara Westwood, 1840 (Hymenoptera, Formicidae) from Cambodia https://jhr.pensoft.net/article/82490/ Journal of Hymenoptera Research 91: 357-374

DOI: 10.3897/jhr.91.82490

Authors: Shingo Hosoishi, Seiki Yamane, Heng Sokh

Abstract: Several phragmotic species in the ant genus Carebara Westwood, 1840 with a cephalic shield are known from the Old World, but species with an anteriorly truncated head seem to be unknown until now. A new species, resembling the phragmotic workers of the ant genus Colobopsis, is here described as Carebara colobopsis Hosoishi & Yamane, sp. nov., based on major and minor worker found in Cambodia. This new species is similar to Carebara acutispina (Xu) and C. obtusidenta (Xu) in some important characters, but distinguished from the latter two by distinct metanotum and deep groove in front of metanotal disc in the major worker, and longer head and deep metanotal groove in the minor worker. This is the first confirmed record of a truncated phragmotic head in the major worker of the genus Carebara. We propose the Carebara acutispina species group to include all the three species, present a diagnosis of this group, and provide a key to species based on the major and minor worker castes.

On cold hardiness of the egg parasitoid wasp Telenomus tetratomus (Thomson, 1861) (Hymenoptera, Scelionidae) – a population regulator of the Siberian moth https://jhr.pensoft.net/article/83765/ Journal of Hymenoptera Research 91: 27-39

DOI: 10.3897/jhr.91.83765

Authors: Nina A. Bulakhova, Zoya A. Zhigulskaya, Lyudmila P. Gashkova, Daniil I. Berman

Abstract: Among the factors contributing to the initiation of outbreaks of the Siberian moth, a dangerous pest of the coniferous forests of Northern Eurasia, it is considered important to reduce the regulatory impact of entomophages. One of the most effective regulators of the pest abundance is the egg parasitoid wasp Telenomus tetratomus (Thomson, 1861). There is an established opinion that T. tetratomus is less cold-resistant than caterpillars of the Siberian moth, and outbreaks of the pest are provoked by cold winters, during which conditions (low temperatures and low snow cover depth) are tolerated by the moth caterpillars but lead to death of the parasitoid. However, the lethal temperature for T. tetratomus was determined in an insufficiently controlled experiment more than 60 years ago. We evaluated one of the cold hardiness characteristics of T. tetratomus, the supercooling point (SCP), which had not been measured previously. Both the host and the parasitoid overwinter in a supercooled state, and freezing is lethal to both. The mean SCP of T. tetratomus (-21.2±0.2 °C) was found to be 6.3 °C lower than the SCP of Siberian moth caterpillars. Comparison of SCP distributions and mortality rates at several temperatures allows us to tentatively estimate 50% mortality temperature of the wasp – about -16 °C. The obtained result, analysis of temperatures in the litter of various types of coniferous forests, and published data indicate that the asynchronous mortality of the host and its main parasitoid during wintering, due to differences in cold hardiness, can be considered as the cause of outbreaks of the Siberian moth mass reproduction only with caution.

Integrative taxonomy based on morphometric and molecular data supports recognition of the three cryptic species within the Encyrtus sasakii complex (Hymenoptera, Encyrtidae) https://jhr.pensoft.net/article/75807/ Journal of Hymenoptera Research 90: 129-152

DOI: 10.3897/jhr.90.75807

Authors: Andrey Rudoy, Chao-Dong Zhu, Rafael R. Ferrari, Yan-Zhou Zhang

Abstract: Morphometrics has established itself as one of the most powerful tools for species delimitation, particularly for morphologically-conserved groups of insects. An interesting example is the parasitoid Encyrtus sasakii Ishii (Hymenoptera: Chalcidoidea: Encyrtidae), which was recently subdivided into three cryptic species that are seemingly well-delimited with the available DNA data but nearly indistinguishable morphologically. Here, we performed linear morphometric analyses of the antenna as well as shape analyses of the ovipositor and hypopygium (the last two are key structures associated with host location and selection) to shed further light on the taxonomic status of the E. sasakii complex. Principal component analyses were carried out to visualize the amount and direction of shape variation in the ovipositor and hypopygium. Complementarily, we constructed phylogenetic trees using a Bayesian approach based on two markers (28S and COI). We found statistically-significant differences in the relative size of the funicle and of the two proximal claval antennomeres among the three species. Our analyses also indicated that the outer plates of the ovipositor show remarkable allometric changes and that both the stylus and shield of the ovipositor are relatively well conserved among species. We nonetheless found consistent interspecific differences in the shape of the 2nd outer plate of the ovipositor and hypopygium. Also, both our COI and combined trees recovered three strongly-supported major clades, each corresponding to one of the three cryptic species. We discuss that changes in the shape of the ovipositor may have played an important role in host shift and speciation within the E. sasakii complex. Even though the recent descriptions of both E. eulecaniumiae Wang & Zhang, 2016 and E. rhodococcusiae Wang & Zhang, 2016 appear not to fully satisfy the International Code of Zoological Nomenclature, a simple resolution for the sake of taxonomic stability is proposed herein.

First report on pollinating behavior of the small carpenter bee Ceratina ridleyi Cockerell (Hymenoptera, Apidae) in Globba leucantha var. bicolor Holttum (Zingiberaceae) https://jhr.pensoft.net/article/79930/ Journal of Hymenoptera Research 90: 173-183

DOI: 10.3897/jhr.90.79930

Authors: Nivaarani Arumugam, Nor Syahaiza Ahmad Zamri, Jayaraj Vijaya Kumaran, Maryana Mohamad Nor, Sreeramanan Subramaniam, Suganthi Appalasamy

Abstract: Small carpenter bees of the genus Ceratina are widespread, but little-studied as pollinators despite their presence in various pollinator assemblages. This study documents the importance of Ceratina ridleyi as a pollinator of the small-flowered Malaysian ginger Globba leucantha var. bicolor. Species of Zingiberaceae are defined by peculiar floral morphologies (e.g staminodes and a single functional anther) but are rarely studied for their insect pollinators. Surprisingly, C. ridleyi was revealed as the single pollinator of Globba leucantha’s showy flowers even though the presence of Apis sp., Trigona sp., and Amegilla sp. were observed in the study site. This small carpenter bee collects both pollen and nectar from the ginger flower. Pollen grains were observed attached to its scopal hairs and hairs on the ventral thorax and ventral abdomen. The bee contacts the flower’s sole stigma only during foraging for pollen, where the stigma contacts pollen accumulated on hairs of the bee’s ventral thorax and ventral abdomen. This study represents the first pollination report of a Ceratina pollinating a species of Zingiberaceae, and only the second report of any Ceratina pollinating a flower with complex morphology.

Integrated taxonomy unveils new species of Trigonalyidae (Insecta, Hymenoptera) from Yunnan, China https://jhr.pensoft.net/article/80150/ Journal of Hymenoptera Research 90: 101-128

DOI: 10.3897/jhr.90.80150

Authors: Bing-Lan Zhang, Cheng-Jin Yan, Cornelis van Achterberg, Yan-Qiong Peng, Hua-Yan Chen

Abstract: Trigonalyidae are rarely collected hyperparasitoids that attack the larvae of Ichneumonoidea, and Tachinidae associated with phytophagous sawfly or Lepidopteran larvae, or primary endoparasitoids of Vespidae larvae. Trigonalyidae mainly occur in tropical and subtropical regions, but recent studies indicate that they are found to be fairly common in mountainous regions. In this study, DNA barcoding methods based on sequences of the COI gene were used to discriminate Trigonalyidae species from Yunnan Province, which is situated in a mountaineous area of southwest China. In total, 25 COI sequences belonging to 14 morphospecies of four genera were obtained. The intraspecific pairwise distances ranged from 0 to 3.3% and the interspecific pairwise distances ranged from 5.3% to 17.3%. The delimitations of all studied species are congruent with the morphological identification results in both ABGD and bPTP methods. Based on both morphological and molecular analyses, four species from Yunnan are described as new: Jezonogonalos eburnalva Zhang & Chen, sp. nov., Lycogaster umbonata Chen & van Achterberg, sp. nov., Taeniogonalos albidorsalis Zhang & Chen, sp. nov., and T. paradoxica Zhang & Chen, sp. nov.

Abstract: Celonites ivanovi sp. nov. is described as a new species from Dagestan where it has been recorded from dry habitats in a small area on the northern side of the Greater Caucasus. Celonites cagrii sp. nov. is described from Erzurum Province in east Turkey. As in other members of the C. cyprius-group, the females of both species were observed to visit flowers of Heliotropium (Boraginaceae). A morphological examination including the male genitalia of all species of the C. cyprius-group revealed that C. ivanovi sp. nov. and C. cagrii sp. nov. share the apomorphic characters of this group and are closely related to Celonites osseus Morawitz, 1888. Mean genetic distance between C. ivanovi sp. nov. and C. cagrii sp. nov. based on COI-5 sequences is 7.40%. The geographical distribution of all members of the C. cyprius-group is summarized and an illustrated key is provided for the identification of males and females of the species. A lectotype is designated for C. osseus.

The genus Orionis Shaw (Hymenoptera, Braconidae, Euphorinae) in the Old World https://jhr.pensoft.net/article/76177/ Journal of Hymenoptera Research 88: 133-145

DOI: 10.3897/jhr.88.76177

Authors: Gavin R. Broad, Julia Stigenberg

Abstract: The euphorine braconid genus Orionis Shaw, 1987 is found to be more diverse in the Old World than had previously been recognised. Orionis was regarded previously as largely Neotropical, with one Oriental species (Orionis orientalis Shimbori & Shaw, 2016) known from Thailand, but we recognise an additional three species from the Oriental and Palaearctic regions. Three species of Euphorinae are transferred to Orionis Shaw, 1987 and are new combinations: Orionis coxator (Belokobylskij, 1995), comb. nov., Orionis erratus (Chen & van Achterberg, 1997), comb. nov., and Orionis flavifacies (Belokobylskij, 2000), comb. nov. Previously known from the Far Eastern Palaearctic, O. coxator has surprisingly been found in Europe, in Belgium, England and the Netherlands. The inclusion of these species in Orionis, whereas most previous species have been described from the Neotropics, is justified by Bayesian analysis of the D2 region of 28S, Cytochrome Oxidase I barcode sequences, and morphology.

Abstract: Species of the genus Oxyscelio Kieffer are egg parasitoids of Orthoptera. The genus is relatively diverse in China, with 34 described species. Some species of the genus are extremely morphologically similar and difficult to identify, especially in males. In this study, DNA barcoding based on sequences of the COI gene was used to discriminate Oxyscelio species from southern China. In total, 49 COI sequences belonging to 22 morphospecies were obtained. The COI sequences worked well for the identification of all the studied species, with intraspecific genetic distances ranging between 0 and 4.3%, while interspecific distances ranged between 7.1% and 19%. Based on both morphological and molecular analyses, five species are described as new: O. amalocarina Mo & Chen, sp. nov., O. apheles Mo & Chen, sp. nov., O. latheticus Mo & Chen, sp. nov., O. stenos Mo & Chen, sp. nov., and O. striae Mo & Chen, sp. nov.

Abstract: Psix striaticeps (Dodd) is an egg-parasitoid wasp previously known only from the Old World. We report this species from twelve counties in Florida, which are the first records in the Western Hemisphere. It was collected in yellow cylinder traps and reared from the eggs of three stink bug species: Nezara viridula L., Chinavia marginata (Palisot de Beauvois), and Piezodorus guildinii (Westwood). A COI barcode analysis found a 100% match between the Floridian population and a specimen from South Africa. The prospects of using Ps. striaticeps as a biological control agent against exotic stink bugs are discussed.

In addition to describing a new species, we report new host associations, provide COI barcodes for four of these species, and discuss host-related intraspecific variation in T. darreh and T. perepelovi.

Stars in subtropical Japan: a new gregarious Meteorus species (Hymenoptera, Braconidae, Euphorinae) constructs enigmatic star-shaped pendulous communal cocoons https://jhr.pensoft.net/article/71225/ Journal of Hymenoptera Research 86: 19-45

DOI: 10.3897/jhr.86.71225

Authors: Shunpei Fujie, So Shimizu, Koichi Tone, Kazunori Matsuo, Kaoru Maeto

Abstract: A new gregarious braconid parasitoid wasp of Euphorinae, Meteorus stellatus Fujie, Shimizu & Maeto sp. nov., is described from the Ryukyu Islands in Japan, based on an integrative taxonomic framework. The phylogenetic position of the new species within the Meteorini was analyzed based on DNA fragments of the mitochondrial cytochrome c oxidase 1 (CO1) and the nuclear 28S rDNA genes. The new species was recovered as a member of the versicolor complex of the versicolor + rubens subclade within the pulchricornis clade. The new species is a gregarious parasitoid of two Macroglossum species (Lepidoptera: Sphingidae) and constructs single or several unique star-shaped cocoon masses separately suspended by very long threads. The evolution of gregariousness and spherical cocoon masses is discussed.

Authors: Sangjin Kim, Željko Tomanović, Yeonghyeok Yu, JuHyeong Sohn, Yunjong Han, Gyeonghyeon Lee, Hyojoong Kim

Abstract: Several species of the genus Aphidius are well known as commercial biocontrol agents of pest aphids, and more than 130 species of the genus have been recorded worldwide. To date, only 15 Aphidius species have been recorded in South Korea. Using the DNA barcode region (ca. 658 bp) of mitochondrial cytochrome c oxidase subunit I (COI), we amplified sequences of 15 Aphidius Korean species, aligned them in combination with 23 reference species retrieved from GenBank for comparison and identification, and then reconstructed a barcode phylogeny by the neighbour-joining method. As a result, three Aphidius species were found to be new to Science. Descriptions and illustrations of the three species new to Science – Aphidius longicarpus sp. nov., A. longistigmus sp. nov., and A. asiaticus sp. nov. – are provided, together with their phylogenetic position within the genus Aphidius. In addition, a redescription of A. areolatus, a parasitoid of maple aphids (Peryphillus spp.), is also given.

A new genus of anaxyelid wood wasps from the mid-Cretaceous and the phylogeny of Anaxyelidae (Hymenoptera) https://jhr.pensoft.net/article/73161/ Journal of Hymenoptera Research 86: 151-169

DOI: 10.3897/jhr.86.73161

Authors: Jia Gao, Michael S. Engel, Chungkun Shih, Dong Ren, Taiping Gao

Abstract: Two new species of wood wasps (Anaxyelidae), Orthosyntexis elegans gen. et sp. nov. and Orthosyntexis thanti sp. nov., are described from mid-Cretaceous Kachin amber. Orthosyntexis gen. nov. exhibits characters and character combinations unique to the family, such as the combination of two mesotibial spurs, a length ratio of forewing 1Rs to 1M<1, a length to width ratio of forewing cell 1mcu ≥ 2, and the presence of 2M+Cu in the hind wing. The new species and morphological characters allow for an exploration of anaxyelid phylogeny. The phylogenetic results indicate that Anaxyelidae are monophyletic and it is suggested to classify the genera in two subfamilies, Syntexinae and Anaxyelinae, the latter including Kempendajinae and Dolichostigmatinae.

DOI: 10.3897/jhr.84.66367

Authors: Serguei A. Simutnik, Evgeny E. Perkovsky, Dmitry V. Vasilenko

Abstract: Another earliest representative of the family Encyrtidae, Sakhalinencyrtus leleji Simutnik gen. et sp. nov., is described and illustrated based on a male specimen from the middle Eocene Sakhalinian amber. Similarly to other Encyrtidae from Sakhalinian amber, the new fossil fundamentally differs from encyrtids from late Eocene European ambers as well as from modern ones. Moreover, it probably belongs to a stem group of the family. The new genus is characterized by extremely apical position of cerci, long veins of the forewing with expanded parastigma, stigmal vein with long uncus, and absence of filum spinosum. The forewing venation of the new genus is very similar to that of Sugonjaevia Simutnik, 2015, but these genera differ by the structure of Mt8, hypopygium, genitalia, and clava.

Authors: Petr Bogusch

Abstract: Epeolus is one of the more species-rich genera of cuckoo bees globally. Seventeen species are known from Europe, and 23 species have been recorded from various countries in the Middle East and North Africa. Epeolus iranicus sp. nov. and E. priesneri sp. nov. are newly described in this study, and E. seraxensis Radoszkowski, 1893, stat. nov., previously a subspecies of E. transitorius Eversmann, 1852, is regarded as a valid species and a lectotype is designated. The first records of E. ibericus and E. intermedius from North Africa are given, and the distribution of E. fallax in North Africa is confirmed. This study compiles known distributional records of the species of this genus from the studied region and provides an overview of the known species richness in the studied countries. Based on available records, Turkey (14 species), Morocco (11) and Iran (9) host the highest numbers of species of Epeolus, whereas in four countries only a single species has been recorded, and the presence of this genus in seven countries has yet to be confirmed.

The velvet ant genus Pseudophotopsis André, 1896 (Hymenoptera, Mutillidae) in the Arabian Peninsula, with the description of two new species https://jhr.pensoft.net/article/65252/ Journal of Hymenoptera Research 82: 361-415

DOI: 10.3897/jhr.82.65252

Authors: Ahmed Mostafa Soliman

Abstract: The monotypic subfamily Pseudophotopsidinae Bischoff, 1920 (Hymenoptera: Mutillidae) from the Arabian Peninsula is revised. Six Pseudophotopsis species are reported from Saudi Arabia, Oman and Yemen. Two new species, P. dhofarensis sp. nov. (male) from Oman and P. subaurea sp. nov. (male) from Saudi Arabia, are described and illustrated. The hitherto unknown female of P. mascatiana Invrea, 1962 is described and P. aegyptiaca (Bischoff, 1920) (female) is associated and synonymized with P. maura Bischoff, 1920 (male). An illustrated key for the species and their distribution in the Arabian Peninsula are provided.

A new species and two new records of the genus Pseudepipona de Saussure, 1856 (Hymenoptera, Vespidae, Eumeninae) from China, with a key to the Chinese species https://jhr.pensoft.net/article/64011/ Journal of Hymenoptera Research 82: 285-304

DOI: 10.3897/jhr.82.64011

Authors: Yue Bai, Bin Chen, Ting-Jing Li

Abstract: In present paper, a total of seven species of Pseudepipona is recognized from China, containing one new species and two newly recorded species. The new species Pseudepipona (Pseudepipona) punctulata sp. nov. is described and illustrated in detail. Pseudepipona (Pseudepipona) kozhevnikovi (Kostylev, 1927) and Pseudepipona (Pseudepipona) straminea (André, 1884) are first recorded from China. Four other known species Pseudepipona (Pseudepipona) augusta (Morawitz, 1867), Pseudepipona (Pseudepipona) herrichii (de Saussure, 1856), Pseudepipona (Pseudepipona) lativentris (de Saussure, 1855) and Pseudepipona (Pseudepipona) przewalskyi (Morawitz, 1885) are also diagnosed with some figures. Furthermore, a key to the Chinese species of the genus is provided.

Cladistic analysis of Zethus Fabricius, 1804 (Hymenoptera, Vespidae): a new subgeneric classification https://jhr.pensoft.net/article/65760/ Journal of Hymenoptera Research 82: 253-283

DOI: 10.3897/jhr.82.65760

Authors: Rogério Botion Lopes, James M. Carpenter, Fernando Barbosa Noll

Abstract: Zethus is the largest genus in Vespidae with over 270 species. It is currently divided into four subgenera: Z. (Zethus), Z. (Zethoides), Z. (Zethusculus) and Z. (Madecazethus). While the last three are restricted to certain biogeographic areas, the first is spread through western and eastern hemispheres. Studies have shown possible phylogenetic incongruence regarding this current division and even raised the possibility of paraphyly in the genus. To evaluate this classification, morphological pasimony analyses under implied weights was carried out, examining external morphology and male genitalia. Analyses showed paraphyly of the genus under various “k” values and paraphyly of two subgenera. Ischnocoelia and Ctenochilus are lowered to subgenera of Zethus. Zethus (Madecazethus) is no longer restricted to Malagasy species and now includes those of the African continent as well. Zethus (Zethastrum) subg. nov. is defined for Oriental representatives. Z. (Zethus) is subdivided into three subgenera: Z. (Zethus), Z. (Didymogastra) and Z. (Wettsteinia). Zethus (Zethusculus) and Z. (Zethoides) are monophyletic and hold their status as subgenera. Three species-groups are Incertae sedis: Z. albopictus, Z. pallidus and Z. spinosus.

Additional data on Aphidiinae (Hymenoptera, Braconidae) fauna of Kyrgyzstan, with description of a new species https://jhr.pensoft.net/article/64968/ Journal of Hymenoptera Research 82: 221-235

DOI: 10.3897/jhr.82.64968

Authors: Andjeljko Petrović, Korana Kocić, Jelisaveta Čkrkić, Željko Tomanović

Abstract: Here we present additional data on the Aphidiinae fauna of Kyrgyzstan. We identified 18 Aphidiinae species. One species new to science (Trioxys depressus sp. nov.) is described, while 11 species are reported for the first time: Aphidius avenae Haliday, A. ervi Haliday, A. matricariae Haliday, A. salicis Haliday, A. urticae Haliday, Ephedrus cerasicola Starý, E. niger Gautier, Bonnamour & Gaumont, Lysiphlebus cardui (Marshall), L. confusus Tremblay & Eady, Monoctonus crepidis (Haliday), and Praon yomenae Takada. Current knowledge of Kyrgyz Aphidiinae is summarized and discussed.
