Overview

The following provides information on identifying the genus Entomacis vs. all other hymenoptera.

Higher Level Diagnosis

Entomacis is a genus of the family Diapriidae, which can be identified using the keys in Masner (1993). The genus is placed in the subfamily Diapriinae, tribe Spilomicrini. Masner (1976), Nixon (1980), and Naumann (1982) provide keys to subfamilies. Masner and Garcia (2002) provide the most up-to-date key to diapriine genera (New World) and a diagnosis of the tribe Spilomicrini.
