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.

The phylogenetic relationships among representatives of 64 genera of the cosmopolitan parasitic wasps of the subfamily Doryctinae were investigated based on nuclear 28S ribosomal (r) DNA (~650 bp of the D2\–3 region) and cytochrome c oxidase I (COI) mitochondrial (mt) DNA (603 bp) sequence data. The molecular dating of selected clades and the biogeography of the subfamily were also inferred. The partitioned Bayesian analyses did not recover a monophyletic Doryctinae, though the relationships involved were only weakly supported. Strong evidence was found for rejecting the monophylies of both Doryctes Haliday, 1836 and Spathius Nees, 1818. Our results also support the recognition of the Rhaconotini as a valid tribe. A dispersal\–vicariance analysis showed a strong geographical signal for the taxa included, with molecular dating estimates for the origin of Doryctinae and its subsequent radiation both occurring during the late Paleocene\–early Eocene. The divergence time estimates suggest that diversification in the subfamily could have in part occurred as a result of continental break-up events that took place in the southern hemisphere, though more recent dispersal events account for the current distribution of several widespread taxa.
