Diagnosis

Fore wing with submarginal vein with 3 or more setae dorsally. Postmarginal vein present but short: less than 0.5 stigmal vein (STV) length.
Scape not reaching apex of vertex. Antenna with usually two anelli; funicle 2-segmented in both sexes and club 3-segmented.
Head usually without fronto-facial suture and with a transverse short groove from eye margin to scrobal cavity about halfway between ocellus and torulus. Malar sulcus present and straight. Vertex strongly vaulted: it extends more than 1/3 of eye length above the eye.
Mesosoma usually with fine dense reticulation. Axillae (ax) situated anteriorly to the posterior margin of the mesoscutum and elongated. Notauli (not) curving to axillae (ax). Scutellum with 2 pair of setae and with 1 pair of longitudinal grooves, which however may be sometimes faint and difficult to see. Propodeum usually without a complete median carina and without plicae. Petiole not distinct.

Overview

Zagrammosoma contains about 15 species and is mainly found in the Americas; although there are a few species from Africa, Europe and Australasia (Noyes, 2002; 2003). Species are mainly parasitoids of lepidopterous leafminers, although a few species are known to attack agromyzids.

Identification

Zagrammosoma is included in recent generic keys to eulophids for Australasia (Boucek, 1988) and North America (Schauff et al, 1997), and it is included in a web-based key to all Eulophidae genera which attack leafmining Agromyzidae (Reina & La Salle, 2003). Zagrammosoma is quite close to Cirrospilus, and differences between them have been discussed by Boucek (1988), La Salle (1989), Hansson and La Salle (1996) and Ubaidillah et al (2000).
