Tridyminae revived status

Tridymina Thomson, 1876. Type genus: Tridymus Ratzeburg, 1848. Treated as Tridyminae by Ashmead (1904).

Diagnosis.

Body usually metallic, except Calyconotiscus Narendran & Saleem. Antenna with 4 or 5 large flagellomeres and at least one anelliform flagellomere before clava (Fig. 52 ). Eyes not divergent ventrally. Marginal vein at most 3 × as long as the relatively long stigmal vein. Petiole without dorsal lamina.

Discussion.

The subfamily Tridyminae is removed from synonymy with Pireninae to include Gastrancistrus Westwood new placement and related genera. Calyconotiscus Narendran & Saleem new placement, Ecrizotes Förster new placement, Epiterobia Girault new placement, Melancistrus Graham new placement, Oxyglypta Förster new placement, Premiscogaster Girault new placement, Sirovena Bouček new placement, Spathopus Ashmead new placement, and Spinancistrus Kamijo new placement are here confirmed to belong to this subfamily.
