Trigonoderopsini Rasplus & Mitroiu, new tribe

Type genus.

Trigonoderopsis Girault, 1915.

Diagnosis.

Antenna variously with 11 flagellomeres, either with 1 anellus and 5 funiculars, 2 anelli and 5 funiculars, 1 anellus and 6 funiculars, or with 1 anellus and 7 funiculars in some males but then with only 2 clavomeres. Pronotum not medially divided (Fig. 89 ). Ovipositor sheaths not expanded.

Discussion.

Next generation molecular data (Cruaud et al., submitted) place Trigonoderopsis Girault and Bugacia Erdős new placement in Colotrechninae , as the sister group of Colotrechnini , instead of their previous placements in Pireninae or (in the case of Bugacia ) dubiously in Ormocerinae . The reduced antennal flagellum helps diagnose this emergent group, and the relatively large mandible with 4 mandibular teeth may also help diagnose the tribe, although this feature is variable in Pteromalidae .
