Morphological convergence is a frequently observed pattern that occurs in species with similar environments,\ trophic niches, and/or life history strategies. In particular, adaptive morphological convergence is\ common in small, highly diverse invertebrate taxa sharing similar life history strategies such as parasitoidism.\ The genus Notiospathius is a braconid parasitoid wasp group with a vast, undetermined number\ of species distributed throughout the Neotropics. Members of this genus possess a considerably elongated,\ petiolate first metasomal tergite. This structure, however, also occurs in species of other doryctine\ genera, both closely and distantly related, probably due to adaptation for attacking wood and bark boring\ coleopteran larvae. Here we investigated the phylogenetic relationships among 117 species assigned to\ Notiospathius, including species of its closely related genera Masonius and Tarasco, as well as members\ of a number of other doryctine genera in order to test its monophyly. Separate and concatenated Bayesian\ partitioned analyses were carried out using two mitochondrial and three nuclear gene markers. The influence\ of each gene on the overall topology was verified using a cross-validation analysis for each marker\ with a \‘\‘leave-one-out\’\’ approach. Moreover, the historical biogeography of Notiospathius was assessed\ calculating divergence time estimates of clades with BEAST and performing ancestral area reconstruction\ analyses both with RASP (Bayesian and S-DIVA) and Lagrange (DEC). All analyses recovered a polyphyletic\ Notiospathius consisting of three separate clades that were more related to other doryctine genera\ than to each other. The relationships reconstructed could not be used to confidently establish the limits\ of Notiospathius with respect to its closely related genera Tarasco and Masonius, and thus the generic status\ of the latter two taxa is maintained. Our divergence time estimates and ancestral area reconstructions\ indicate that the most recent common ancestor of Notiospathius sensu stricto originated in the Caribbean\ subregion during the Oligocene\–Miocene boundary, and subsequently diversified during the mid- to late\ Miocene, radiating throughout the Neotropics.

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.

We describe seven new species of the doryctine wasp genus Notiospathius Matthews \& Marsh from Northwest Venezuela: N. araguae sp. n., N. bolivari sp. n., N. curvilineatus sp. n., N. dantei sp. n., N. estradae sp. n., N. larensis sp. n., and N. venezuelae sp. n. These represent the first described species of the genus reported for this country. Species boundaries for the above taxa were confirmed using the General mixed Yule-coalescent method with 441 DNA barcode sequences from specimens assigned to Notiospathius and other closely related genera collected in different countries along the Neotropics.

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.
