The Doryctinae is one of the most specious subfamilies of the mainly parasitoid wasp family Braconidae. Members of this subfamily are characterised by having a very heterogeneous external morphology, which has made establishing the limits of several of its genera extremely difficult. The Neotropical Callihormius Ashmead, Platydoryctes Barbalho & Penteado-Dias, and Aphelopsia Marsh are prime examples of this, since they show extensive interspecific morphological variation but lack consistent diagnostic features among them. We carried out a comprehensive phylogenetic study among several representative species belonging to the above genera as well as other morphologically similar doryctine taxa based on three nuclear and two mitochondrial (mt)DNA sequence markers. Based on the relationships recovered, we assessed the generic limits among the examined taxa and investigated the times of origin and diversification in this group. Our best estimate of phylogeny did not recover Callihormius as monophyletic, and thus we propose a taxonomic arrangement where we elevate the status of Ca. (Dmitriohormius) Belokobylskij, Zaldívar-Riverón & Coronado-Blanco to genus level, stat. nov., and also describe four new genera: Macrometasoma, gen. nov., Caputlenis, gen. nov., Platyhormius, gen. nov. and Caputrugosus, gen. nov. Platydoryctes is delimited morphologically, and the body flatness is proposed to have independently evolved more than once within the group of genera examined. Aphelopsia was not recovered as monophyletic, though the relationships involved were weakly supported and therefore we maintain its species composition. Panama Marsh, stat. rev., which was considered a junior synonym of Leluthia Cameron, is resurrected. Basal relationships in the phylogeny had very short branch lengths, which could be due to ancient rapid radiation events that occurred during the early evolution of the group. The estimated times of divergence showed that the clade containing Callihormius and its related genera originated between the late Oligocene and middle Miocene, whereas its early diversification events probably occurred between the middle to late Miocene.

The taxonomy of the American doryctine genus Callihormius is revised. Four Nearctic species are redescribed, including the type species of the genus (C. bifasciatus Ashmead, 1900, C. stigmatus Marsh, 1966, C. texanus Marsh, 1966 and C. werneri Marsh, 1966). Four Neotropical species are also described: C. circumlitoris sp. nov., C. franciscomartoi sp. nov., C. palagannensis sp. nov. and C. tayronensis sp. nov. Callihormius longicaudatus (Nettleton, 1938) is considered as “incertae sedis”. A taxonomic key for the 13 currently recognised species of Callihormius is provided.

The evolutionary relationships among most (143 genera) of the currently recognized genera of the braconid wasp subfamily Doryctinae were investigated using maximum parsimony analysis, employing 100 characters from external morphology and four additional, less well-studied character systems (male genitalia, ovipositor structure, venom apparatus and larval cephalic structure). We investigated the ‘performance’ of characters from external morphology and the other character systems and the effects of abundant missing entries by comparing the data decisiveness, retention and consistency indices of four different character partitions. The results indicate that the performances of the different partitions are not related to the proportions of missing entries, but instead are negatively correlated to their proportion of informative characters, suggesting that the morphological information in this group is subject to high levels of homoplasy. The external morphological partition is significantly incongruent with respect to a data set comprising the other character systems based on the ILD test. Analyses supported neither the monophyly of the large tribes Doryctini and Hecabolini, nor the monophyly of the Spathiini and Heterospilini. Relationships obtained from successive approximation weighting analysis for the complete data differ considerably from the currently accepted tribal and subtribal classifications. The only exceptions were the Ypsistocerini and the Ecphylini, whose recognized members were recovered in single clades. A close relationship between the Binaerini and Holcobraconini, and also Monarea, is consistently supported by venom apparatus and ovipositor structure characters but is not indicated by external morphological data. Low bootstrap values obtained for most of the recovered clades in all analyses do not allow us to propose a meaningful reclassification for the group at this time. A complete list of the recognized genera and their synonymies is given.

Background and aims. The preliminary results of a DNA barcoding study of the doryctine fauna of parasitoid wasps from the Chamela–Cuixmala Biosphere Reserve in Mexico, a region dominated by tropical dry forest, are presented. So far, three field trips have been carried out to the reserve and 468 specimens have been collected, of which 407 cox1 sequences were obtained.
Materials and methods. The general mixed Yule-coalescent model was applied to a phylogram to investigate the number of evolutionary units that can be detected from the DNA sequence data examined.
Results. A total of 185 barcoding species assigned to 20 identified doryctine genera were discriminated using the above model, 115 of which belong to the speciose genus Heterospilus, pointing out the extraordinary species richness of this subfamily of insects in a Mexican tropical dry forest.
Conclusion. On the basis of the DNA barcodes generated, Ptesimogastroides Braet & van Achterberg is proposed to be a junior synonym of Ptesimogaster Marsh syn. nov. Neoheterospilus was also found deeply nested within a large Heterospilus clade, suggesting the paraphyly of the latter genus.
