Complete suture present across vertex. Head and mesosoma smooth or weakly sculpted. frontal grooves extending above median ocellus, to top of eye; malar sulcus split ventrally, but often very difficult to see. The only known North American species has brachypterous females; macropterous specimens with forewing fringe setae very long, about 0.5x transverse width of wing. Petiole quadrate to longer than broad, conspicuous. Compare with: Thripobius.

1a-b: Entedonastichus head and mesosoma (left), and female antenna (right)

Biology: Parasitoids of thrips.

Comments: 6 described species. Synapomorphies (split malar sulcus, frontal groove extending above lateral ocellus) indicate a close relationship with Thripobius.

Thripobius: Petiole much broader than long.
