Diglyphus Walker, 1844 comparative info return to: prev home
2 funicular segments, 3 claval segments; scape rarely swollen, if so (in D. pedicellus Gordh & Hendrickson males) then pedicel also swollen and almost as long as scape. Notauli almost always incomplete, sometimes faintly complete but divergent posteriorly, ending in anterior half of the strongly advanced axillae; scutellum with parallel submedian grooves. Postmarginal vein 1-2x stigmal vein length. Compare with: Diaulinopsis, Cirrospilus.

Biology: Parasitoids of leaf-mining Diptera.

Comments: Many described species.

Comparative information:

Diaulinopsis: Notauli complete and nearly straight, reaching scutellar margin or ending in axillae narrowly separated from scutellar margin. Scape always strongly swollen in males. Postmarginal vein at least 2x stigmal vein length.

Cirrospilus: Notauli straight (or nearly so) and complete, reaching scutellar margin or ending in axillae narrowly separated from scutellar margin.
