Abstract

Based on a phylogenetic analysis, the limits of Therophilus (Hymenoptera: Braconidae: Agathidinae) are redefined and restricted to a small proportion of the previously included species. Those species belonging to the world fauna are listed and the species from Thailand are revised. Forty-four species are assigned to the genus including 11 new species, i.e. Therophilus anuchati, Therophilus apichati, Therophilus areeluckae, Therophilus boonthami, Therophilus chiangmaiensis, Therophilus kwanuiae, Therophilus songrami, Therophilus sukpengae, Therophilus wannai, Therophilus wongchaii, Therophilus wongwani. A dichotomous key to species is presented; links to an electronic interactive key and to distribution maps are also included.

Introduction

Agathidinae is a moderately large subfamily of Braconidae with 1, 069 described species worldwide and 246 in the Oriental Region (Yu et al. 2005), though there are an estimated 2, 000–3, 000 species awaiting description worldwide (Sharkey et al. 2006). The subfamily has a worldwide distribution and members are found in most terrestrial habitats. The history of higher classification of the Agathidinae was summarized by Sharkey (1992) who also proposed a tribal level classification based on ground-plan coding. Sharkey et al. (2006) conducted phylogenetic analyses based on morphology and the D2–D3 regions of 28S rDNA. The Oriental fauna of Agathidinae were first revised by Bhat and Gupta (1977) and they provided a detailed history of taxonomic research for the area. Sharkey et al. (2009) revised the Oriental genera of Agathidinae. Van Achterberg and Long (2010) revised the Vietnamese agathidine fauna. Sharkey and Clutts (2011) revised the Thai species of Biroia, Braunsia, Camptothlipsis, Coccygidium, Cremnops, Cremnoptoides, Disophrys, Earinus, Gyrochus, Lytopylus, and Troticus, and included a key to the Agathidinae genera of the Oriental region. Sharkey and Stoelb (in press) revised the Thai species of Zelodia. This paper is the third in a series to revise all Thai species of Agathidinae. The genera Aneurobracon, Bassus s.s., Euagathis, and Therophilus s.l. will be dealt with in subsequent publications.

Methods

As part of the inventory of Thai insects, we ran 3 Malaise traps at each of 30 different localities throughout Thailand from 2007-2010, comprising approximately 90 Malaise traps. The specimens dealt with here are primarily from these traps.

Species concepts are based on morphological data and 28S rDNA data. Regions D2-D3 of 28S rDNA (roughly 560 base pairs) were sequenced using the following primers: 28SD2hymF 5’ - AGAGAGAGTTCAAGAGTACGTG - 3’ and 28SD3hymR 5’ - TAGTTCACCATCTTTCGGGTC - 3’. Sequences were edited using Geneious Pro v4.7.5 (Drummond et al. 2009) and aligned based on a secondary structure model for Ichneumonoidea developed by Yoder and Gillespie (2004) and Gillespie et al. (2005). Regions of expansion and contraction (RECs), regions of slipped-strand compensation (RSCs), and short regions of alignment ambiguity were further aligned/corrected by eye. Three of these regions (~30 base pairs total) were deleted because they could not be aligned with any confidence, i.e., there were multiple equally supported alignment options.

Phenetic and phylogenetic trees were constructed using neighbor-joining (NJ), maximum parsimony (MP) and Bayesian methods. MP was performed using TNT (Goloboff et al. 2008) [traditional search with 100 random addition sequences followed by branch-swapping, saving 100 trees per replication; 1000 bootstrap replications were used to estimate branch reliability]. The Bayesian analysis was performed using MrBayes v3.1.2 (Ronquist and Huelsenbeck 2003). Best-fitting DNA substitution models were determined using MrModeltest2.2 (Nylander 2004). The general time reversible model of evolution with a parameter for invariant sites and rate heterogeneity modelled under a gamma distribution (GTR+I+G) was determined as the best-fitting model. The Bayesian analysis consisted of two independent Bayesian MCMC runs initiated from different random starting trees. The analysis ran for 5, 500, 000 generations, reaching a topological similarity criterion of 0.01; trees were sampled every 500 generations. 25% of the trees from each run were removed as burn-in upon topological convergence. The NJ tree was produced from PAUP* (Swofford 2003) using default settings. Figure 2 presents the NJ tree, which was more resolved than the phylogenetic trees produced by MP and Bayesian analyses. We mapped the support values of the Bayesian and MP analyses on the NJ tree.

Figure 2.

NJ phylogram based on 28S rDNA. Where Bayesian and parsimony analyses agreed with the NJ tree, branch support values are included in the figure, i.e., Bayesian posterior probabilities/parsimony bootstrap (values below 0.5 posterior probability and/or 50% bootstrap support were not recorded on the tree). Therophilus s.s. highlighted in grey box.

The dichotomous key, descriptions, and the interactive key (Appendices 1–3) were generated using DELTA Editor (Dallwitz et al. 1999), DELTA (Dallwitz et al. 1993), and Intkey (Dallwitz et al. 1995).

Morphological terms follow Sharkey and Wharton (1997) except for the following: measurements are given for the length and apical width of the first metasomal mediotergite (MT1). Measurement of the apical width is straightforward, however since the base of the tergite is usually hidden from view it is difficult to measure the total length. Instead we measure from the apex of the large tendon that emanates from the propodeum and inserts near the base of the median tergite. Abbreviations used in text: MT1, MT2, MT3...MT7: metasomal mediotergite 1, 2, 3...7.

Morphological terms used in this revision were matched to the Hymenoptera Anatomy Ontology (HAO, Yoder et al. 2010) (Appendix 4). Identifiers (URIs) in the format http://purl.obolibrary.org/obo/HAO_XXXXXXX represent anatomical concepts in HAO version http://purl.obolibrary.org/obo/hao/2011-05-18/hao.owl. They are provided to enable readers to confirm their understanding of the anatomical structures being referenced. To find out more about a given structure, including, images, references, and other metadata, use the identifier as a web-link, or use the HAO:XXXXXXX (note colon replaces underscore) as a search term at http://glossary.hymao.org.

All 14 species found in Thailand are treated with a diagnosis and distributional data. They are illustrated with color photos using a JVC digital camera mounted on a Leica MZ16 microscope and Automontage® stacking software. Distributional data are listed for all species and a Google map via Berkeley Mapper is included for all species. The descriptions are of the holotype and variation is given in parentheses.

The source files for the keys, descriptions, illustrations, DNA sequence and distributional data are all freely available to future researchers who may wish to build on these data. Distribution data, pdf’s of non-copywrite references, images, notes, and host and type information can be found by searching Taxabank (a combined specimen and taxonomic database; http://purl.org/taxabank). Codes beginning with an “H” and followed by numbers are unique identifiers used for specimens in the Sharkey lab at the University of Kentucky, and in the specimen database TaxaBank (e.g., H235). All sequences have been deposited in the GenBank database.

Results Phylogeny

Recently the polyphyletic generic concept, Bassus, was divided into four genera, i.e., Bassus s.s., a small monophyletic group confined to the Old World, Lytopylus, a large monophyletic group with a world-wide distribution, Neothlipsis, a small New World genus and Therophilus, a polyphyletic dumping ground for the remaining species. Here we refine the concept of Therophilus so that it is monophyletic. However, this leaves those species that do not fit the concept without a correct generic placement. We refer to these as Therophilus s.l. in this treatment, and they will be treated in a separate publication (Sharkey et al. in prep).

The phylogenetic tree in figure 2 shows that Therophilus in the strict sense, and two new genera, are far removed from the majority of the species of Therophilus sensu latu. The clade containing Therophilus s.s. was referred to as an unnamed new tribe in Sharkey (1996). The monophyly of all agathidine tribes is well supported, though the tribal interrelationships based on 28S remain volatile.

Within Therophilus s.s., there are two distinct clades that may deserve generic status when more is known of their biology and diversity. All members of the lower clade, in figure 2, which includes Therophilus cattienensis, are stout and mostly yellow-orange, e.g., all have predominantly yellow-orange heads. Therophilus conspicuous Wesmael, the type species, belongs in this group. Members of the clade containing Therophilus chiangmaiensis are more gracile and melanic.

Type species.

Microdus (Therophilus) conspicuous [Lectotype ♀ IRSNB, examined]

Diagnosis.

There is neither one character nor a specific combination of characters that distinguishes members of Therophilus from all other agathidines. It is easily separated from members of Cremnoptini and Disophrini by the shape of the tarsal claws, i.e., simple with a basal lobe in Therophilus, versus cleft claws in members of the two aforementioned tribes. Most members of Therophilus have the following combination of diagnostic characters: Apical abscissa of R of fore wing weak at midlength and bent towards apex of wing; interantennal space with two (usually weak and short) longitudinal ridges or with a median keel; postscutellar depression present; cubitus of hind wing strong and tubular, at least basally; subbasal cell of hind wing angled apically at the point from which the cubitus emanates; sclerite between hind coxal cavities and metasomal foramen incomplete or narrow. A combination of characters that distinguishes almost all species of Oriental Therophilus is: Interantennal space with longitudinal groove (Figs. 3c, 6c), sometimes weak (Fig. 8c); posteroscutellar depression present (Fig. 8f); notauli sculptured with pits (Fig. 3f).

Description.

Head. Lateral carina on frons absent (Fig. 3c); interantennal space with longitudinal groove (Fig. 3c, 6c); gena not extended ventroposteriorly into sharp prominence (Fig. 5e); gena lacking sharp angle posteriad eye; labial palpus with three or four segments, third segment much reduced or absent; apical antennomere acute but lacking nipple-like process.

Mesosoma. Propleuron lacking a projection at mid height; notauli impressed and pitted, at least in part (Fig. 3f); posteroscutellar depression present (Fig. 8f) (rarely absent); propodeum from rugose to areolate-rugose (Fig. 7g); sclerite between hind coxal cavities and metasomal foramen narrow, sometimes incomplete.

Legs.Fore tibia lacking pegs, fore tarsal claws with basal lobe; mid tibia with apical and medial pegs; hind tibia with apical pegs.

Wings (Figs. 3b, 4b). Fore wing RS + M vein incomplete; second submarginal cell triangular; fore wing 3RSb decurved, weak at midlength; hind wing r and r-m crossveins absent; hind wing CUb present and strong, tubular at least basally.

Metasoma. MT1 with longitudinal striations, lacking dominant pair of longitudinal carinae (Fig. 4f); MT2 from smooth to striate, usually with some longitudinal striae and weak transverse striae in first transverse depression; MT3 smooth (Fig. 4f); ovipositor as long as or longer than metasoma (Fig. 4a).

Biology.

According to Nixon (1986), Therophilus conspicuus attacks larval Tortricidae. Janzen has reared three species of Therophilus s.s. in Costa Rica; they are parasitoids of Tortricidae and Elachistidae.
