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.

Doryctinae (Hymenoptera : Braconidae) is a large and diverse subfamily of parasitic wasps that has received much attention recently, with new species and genera described and phylogenies based on morphological and/or molecular data that have improved higher-level classification and species delimitation. However, the status of several genera is still unresolved, if not controversial. Here we focus on two related groups of such genera, Dendrosoter Wesmael–Caenopachys Foerster and Ecphylus Foerster–Sycosoter Picard & Lichtenstein. We integrated morphological and molecular (COI and 28S–D2 genes) evidence to highlight, by phylogenetic analyses (maximum likelihood and Bayesian) and a posteriori morphological examination, previously overlooked variation, which is here illustrated and discussed. Monophyly of Dendrosoter and Caenopachys and the presence of synapomorphic morphological characters support synonymy of Caenopachys under Dendrosoter. Low genetic differentiation and high variability for putatively diagnostic morphological characters found in both C. hartigii (Ratzeburg) and C. caenopachoides (Ruschka) supports synonymy of D. caenopachoides under D. hartigii, syn. nov. Morphological and molecular evidence together also indicate independent generic status for Sycosoter, stat. rev., which is here resurrected. This work represents a further advancement in the framework of the ongoing effort to improve systematics and classification of the subfamily Doryctinae.

Metasomal elongation is a common feature in species of various parasitoid Hymenoptera, probably due to adaptive morphological convergence to similar parasitoid strategies. The braconid subfamily Doryctinae is perhaps where this feature has evolved the most times independently. Here we recognise a new Neotropical doryctine wasp genus with a petiolate first metasomal tergum, based on molecular and morphological analysis. The phylogenetic affinities of the new genus within Doryctinae and the relationships among six of its described and three potentially cryptic, undescribed species were reconstructed using sequence data from three genes, wingless, 28SrDNA and COI. The new genus is resolved in a clade together with Semirhytus Szépligeti, Johnsonius Marsh and Parallorhogas Marsh. These four genera share vein m-cu of the hind wing slightly curved distally and the propodeum with a distinct lateral and median longitudinal carina and an apical areola. The relationships recovered among the examined species suggest a South American origin for the new genus and its subsequent diversification into Central America and Mexico. Described as Bolivar, gen. nov., this new taxon comprises eight species, two species previously placed within Notiospathius Matthews & Marsh, B. ornaticornis (Cameron), comb. nov., and B. bribri (Marsh), comb. nov., and six new species (B. ecuadorensis, sp. nov., B. helmuthi, sp. nov., B. pittieri, sp. nov., B. risaraldae, sp. nov., B. teres, sp. nov. and B. tuxtlae, sp. nov.).
