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.

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.

Notiospathius Matthews & Marsh, 1973 is the second most diverse genus of Doryctinae in the Neotropical region, however, in Colombia only two species have been reported and no studies on the diversity of the genus have been conducted. We present a taxonomic synopsis of the genus from Colombia. Principal Component Analysis (PCA) and Discriminant Function Analysis (DFA) allowed the taxonomic evaluation of morphometric characters used by other authors and those proposed in the present study to differentiate the species. Forty seven of 104 characters studied are useful to discriminate the species. Twenty three species are reported. The following new records for Colombia are: Notiospathius angustus Marsh, 2002; N. badius Marsh, 2002; N. bicolor Marsh, 2002; N. ninae Marsh, 2002; N. rugonotum Marsh, 2002; N. shawi Marsh, 2002; N. tinctipennis (Cameron, 1887) and N. venezuelae López-Estrada & Zaldívar-Riverón, 2012. The following 14 new species are described: N. alejandroi sp. nov., N. amazonensis sp. nov., N. carmenae sp. nov., N. cundinamarcensis sp. nov., N. farallonensis sp. nov., N. julianoi sp. nov., N. magdalenensis sp. nov., N. marshi sp. nov., N. payae sp. nov., N. putumayensis sp. nov., N. quimbayensis sp. nov., N. tayronensis sp. nov., N. utriae sp. nov., N. vallensis sp. nov. Notiospathius ugaldei Marsh, 2002 is the junior synonym of N. columbianus (Enderlein, 1912); Notiospathius mariachi Reséndiz-Flores, Nunes and Zaldívar-Riverón, 2014 is the junior synonym of N. carolinae (Marsh, 2002); and N. chinanteco Reséndiz-Flores, Nunes and Zaldívar-Riverón, 2014 is the junior synonym of N. rugonotum Marsh, 2002. A comprehensive taxonomic key with illustrations is presented.

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.).
