Brachistinae


Brachistinae is a subfamily of braconid wasps in the family Braconidae.

Taxonomy and phylogeny

The genera of Brachistinae were formerly classified as tribes under the subfamily Helconinae. The tribe Blacini was split into a separate subfamily, Blacinae. Blacinae was subdivided into the tribes Blacini, Blacozonini, Chalaropini, Dyscoletini, Stegnocellini, and Xyeloblacini. The Helconinae tribes Diospilini, Brulleiini and Brachistini were later split into another subfamily, Brachistinae. Phylogenetic studies by Sharanowski et al. in 2011 found the Blacinae and Brachistinae to represent a monophyletic lineage, resulting in the synonymization of Blacinae under Brachistinae. However, further phylogenomic studies by Jasso-Martínez et al. in 2022 found Dyscoletes to be distant and not monophyletic with other Brachistinae so considered it incertae sedis. The authors also noted weaknesses in the phylogenetics of Brachistinae due to genera being omitted.
