Taxonavigation

Ordo: Hymenoptera
Familia: Pteromalidae

Name

Gahan, 1946 – Wikispecies link – Pensoft Profile

Diagnosis

Intertorular area with prominence that can be a carina or tooth-shaped (also referred to as inner antennal process (iap)). Fore wing disc bare or with setae reduced to setal bases (pilose only in Pteropilosa gen. n.), with marginal fringe, fore wing always with thickened juncture between marginal vein and submarginal vein (parastigma), marginal vein elongate, postmarginal and stigmal vein shortened, postmarginal vein usually shorter than stigmal vein. Mesonotum with complete notauli. Hind tibia with two spurs.

Key to extant and fossil genera of Cerocephalinae

This key is modified after Krogmann (2013) and includes the two new fossil genera described herein.
