Stenocorse is a monotypic genus with wide distribution and a large range of beetle hosts. We analyzed the morphological variation of 346 specimens from the USA south to Brasil. We studied 15 morphometric and 30 discrete characters using principal component (PCA) and discriminant function analyses (DFA) to assess character informativeness and the influence of geographic distribution and host source to detect differentiation. Mexican samples were studied according to location and biogeographic provinces. Specimens from Colombia were studied according to the plant where the host was recorded. Three measurements show group differentiation whereas four were redundant. Three groups of individuals were supported by continuous and discrete characters: one found in the USA, Mexico, Nicaragua and Costa Rica, a second from Mexico, and a third from Colombia and Brazil. These groups showed poor agreement with the differentiation of its common beetle host populations. This could be a consequence of the large number of sympatric host species feeding on a large number of plant species. This research shed light on other sources of evidence for building a sound taxonomy for Stenocorse.

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.

Various DNA sequence-based methods for species delineation have recently been developed to assess the species-richness of highly diverse, neglected invertebrate taxa. These methods, however, need to be tested under a variety of conditions, including the use of different markers and parameters. Here, we explored the species diversity of a species-rich group of braconid parasitoid wasps, the Neotropical genus Notiospathius, including 233 specimens from 10 different countries. We examined sequences of two mitochondrial (mt) (COI, cyt b) and one nuclear (wg) gene fragments. We analysed them separately as well as concatenating the mt data with the general mixed Yule-coalescent (GMYC) model for species delineation using different tree-building methods and parameters for reconstructing ultrametric trees. We evaluated the performance of GMYC analyses by comparing their species delineations with our morphospecies identifications. Reconstructing ultrametric trees with a relaxed lognormal clock rate using the program BEAST gave the most congruent results with morphology for the two mt markers. A tree obtained with wg using the programs MrBayes+Pathd8 had the fewest cases of incongruence with morphology, though the performance of this nuclear marker was considerably lower than that of COI and cyt b. Species delimitation using the coalescent prior to obtain ultrametric trees was morphologically more congruent with COI, whereas the Yule prior was more congruent with cyt b. The analyses concatenating the mt datasets failed to recover some species supported both by morphology and the separate analyses of the mt markers. The highest morphological congruence was obtained with the GMYC analysis on an ultrametric tree reconstructed with cyt b using the relaxed lognormal clock rate and the Yule prior, thus supporting the importance of using alternative markers when the information of the barcoding locus (COI) is not concordant with morphological evidence. Seventy-one species were delimited based on the congruence found among COI, cyt b and morphology. Both mt markers also revealed the existence of seven potential cryptic species. This high species richness from a scattered geographical sampling indicates that there is a remarkable number of Notiospathius species that remains undiscovered.

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.

Seven species of the speciose Neotropical parasitoid wasp genus Notiospathius Mathews et Marsh are redescribed. These species were originally described during the nineteenth and early twentieth centuries. Examination of the holotpyes of N. meliorator and N. necator revealed that they actually belong to an undescribed doryctine genus that is similar to Ptesimogaster Marsh, 1965. A key is provided to distinguish these species.
