Diagnosis

Forewing with a single cell, the radial cell, which may be opened or closed along the anterior margin of the wing.
Antenna with 15 segments in the male, 13 in the female.
Scutellum with a distinct, raised, cup-shaped structure.

Superfamily : Cynipoidea
Family : Figitidae

Classification

Overview

The Eucoilinae is a large and common group containing nearly 1000 species in 83 genera (Ronquist, 1999). This group has previously been treated as either a distinct family or as a subfamily, but recent works now consistently support it as a subfamily of Figitidae (Ronquist, 1995; 1999; Fontal-Cazalla et al. 2002).
Eucoilinae species are solitary, koinobiont endoparasitoids of Diptera. Parasitoids of leafmining Agromyzidae are restricted to two closely related groups, the mostly Holarctic Gronotoma group of genera, and the exclusively Neotropical Zaeucoila group of genera (M. Buffington, pers.comm.). A few species of Gronotoma, and Ganaspidium nigrimanus (Kieffer) (=Ganaspidium utilis Beardsley), are widespread among the Pacific Islands, probably due to movement by human activities (Buffington, 2004).

Identification

There are no recent keys to eucoilid genera which include all the groups attacking leafmining agromyzids.
