Trichacis

Trichacis is a genus of parasitoid wasps in the family Platygastridae. Members of this genus have a tuft of setae on the mesoscutellum and transverse striae or rugulae above the antennae. They are parasitoids of Cecidomyiidae, although the hosts of most species remain unknown.

The genus has been revised for the Nearctic, Neotropics, and Europe. There have been more than 60 species described in Trichacis;  however, many of these have been since synonymized.
