wing with submarginal
vein (SMV) with 3 or more setae dorsally. Postmarginal
vein (PMV) present: at most 1.25 times longer than stigmal vein
(STV), often equal or shorter.
Scape usually slender, sometimes swollen and not exceeding apex of vertex. Funicle 2-segmented and club 3-segmented both in male and female. Fronto-facial suture (ffs) adjacent anterior ocellus and one transverse groove (gr) between eye margin and scrobal cavity placed about halfway between ocellus and torulus. Malar sulcus present and straight. Propleura separated posteriorly and not covering prosternum. Notauli either incomplete, or complete and curving to meet axilla. Scutellum with 2 pair of setae and with 1 pair of longitudinal grooves. Propodeum with or without median carina and always without plicae. Petiole not distinct.

Overview |
Diglyphus contains about 35 species and is cosmopolitan in distribution; although the centre of diversity is clearly in the Holarctic realm (Noyes, 2002; 2003). Species are predominantly parasitoids of agromyzid leafminers, and this is one of the most important genera associated with pest leafminer species. Several species, e.g. D. isaea and D. begini, have figured prominently in biological control programs. | ||||||||||||||||||||||||||

Identification |
Diglyphus 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). Reviews or keys for species of Diglyphus are available for North America (Gordh & Hendrickson, 1979), Britain (Askew, 1968), Europe (Yefremova & Shrol, 1996) and China (Zhu et al., 2000b). |
