Stenocorse (Braconidae) is a doryctine wasp genus widely distributed from southern USA to central Argentina, and it has been reported to be ectoparasitoid of over 60 bruchine (Coleoptera: Chrysomelidae) species. The genus currently contains a single described species, S. bruchivora (Crawford), though recent molecular and morphological evidence revealed that it is actually composed of various undescribed species. Here we redescribe S. bruchivora (Crawford) and describe five new species from various geographic regions along the Neotropics (S. atlanticus sp. nov., S. maesoi sp. nov., S. pacificus sp. nov., S. rosabricenae sp. nov., S. sudamericanus sp. nov.) We could not morphologically distinguish S. atlanticus sp. nov. from S. pacificus sp. nov., though they can be consistently delimited both geographically and with mitochondrial and nuclear DNA sequence data. We include information about the host plant legumes where the recognised species of Stenocorse and their associated bruchines were reared. A key to the recognised species of Stenocorse 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.
