The braconid subfamily Doryctinae is a cosmopolitan, highly diverse group of wasps mainly represented by parasitoid species. In this subfamily, however, there is a group of mainly Neotropical genera whose species are associated with galls of several vascular plant families. Previous molecular phylogenetic studies based on a few markers consistently recovered the monophyly of this group, though various relationships among genera and the monophyly of its most speciose genus, Allorhogas Gahan, remained unresolved. We characterized the mitogenomes of 13 representative species of the gall-associated doryctine clade and performed a phylogenomic analysis with both mitogenome and ultraconserved element (UCE) DNA sequence data to assess the classification of Doryctinae and to examine the evolution of phytophagy within the group. We found different patterns of tRNA gene rearrangements, two of which are present in most of the ingroup taxa. All phylogenetic analyses yielded highly similar, well-supported topologies that are congruent with relationships reported in previous studies. The resulting phylogenies confirmed Percnobracon as sister to the remaining genera and supported two separate clades whose genera are exclusively associated with Ficus (Moraceae). Allorhogas is confirmed to be polyphyletic. The combined evidence also supported a main Allorhogas clade composed of multiple phytophagous species that feed on at least five different host plant families. Further rearing records and phylogenetic studies are needed to examine host plant shifts and to broaden our understanding of a poorly studied radiation of gall-associated wasps.

The braconid subfamily Doryctinae (Hymenoptera) is a cosmopolitan, species-rich group of parasitoid wasps whose known species richness and morphological diversity is mainly concentrated in the Neotropical region. Among the doryctine taxa that are endemic to this region, there is a group of six genera (the Pedinotus genus group) that are mainly characterized by having lateral, posteriorly converging or subparallel grooves on the second metasomal tergite (including Gymnobracon Szépligeti, Hybodoryctes Szépligeti, Lamquetia Braet et van Achterberg, Osmophila Szépligeti, Pedinotus Szépligeti and Trigonophasmus Enderlein). Most of these genera were described more than a century ago, and thus their limits and diagnostic morphological features are not well defined. We present an analysis of the phylogenetic relationships among various representative species of five of the six genera belonging to the Pedinotus genus group based on one mitochondrial (cytochrome oxidase I) and two nuclear (28S, Wingless) gene markers. We also estimated the timing of origin and diversification within the group and investigated the external morphology of the genera involved in order to determine reliable identification characters. The group as a whole, whilst being recovered as monophyletic with the inclusion of Acanthorhogas Szépligeti, was not statistically supported. However, the respective monophyly of all of the morphologically supported genera are confirmed, as are the intergeneric relationships (Gymnobracon, Trigonophasmus) ((Acanthorhogas, Osmophila) (Lamquetia, Pedinotus)). We propose that the pattern of sublateral grooves or depressions appears to be a useful systematic character for recognition of an endemic Neotropical radiation that could have originated c. 41–27 Ma. We redescribe six of the seven genera that we recognize for the Pedinotus genus group and provide a key to enable their identification.

A new braconid genus from the subfamily Doryctinae, Mexiare gen. nov. (type species M. toledoi sp. nov.) is described from the state of Morelos in Central Mexico. The described species of this genus is characterised by having immovably fused first and second metasomal tergites, a feature also present in species of two Oriental (Arhaconotus Belokobylskij and Mimipodoryctes Belokobylskij) and one Neotropical (Iare Barbalho et Penteado-Dias) genera. The new genus, however, can be distinguished from the Neotropical Iare by the presence of a semi-oval basal area on the second metasomal tergite, distinctly short submedial (subbasal) cell of hind wing, more than three hamuli, considerably short second radiomedial (submarginal) cell, narrow radial (marginal) cell of fore wing and mostly smooth mesoscutum. A phylogenetic analysis among doryctine genera based on two gene markers (28S and COI) placed Mexiare gen. nov. within a previously recovered major South American clade, though its relationships with other taxa remain unclear.
