Trigonoderinae new status

Trigonoderini Bouček, 1964. Type genus: Trigonoderus Westwood, 1832.

Diagnosis.

Antenna with 12 flagellomeres. Mandibles often large but not falcate (Fig. 109). Scapula anteriorly exposed by narrow pronotum. Axilla hardly advanced. Axillula usually not enlarged, but if so ( Plutothrix Förster), then it is not convex (Fig. 110). Petiole simple, usually transverse and hardly visible.

Discussion.

Trigonoderinae are relatively distinctive pteromalids that differ from most others in the family in their long, large bodies in combination with complete notauli and a well-indicated frenal groove (displaced posteriorly in Platygerrhus Thomson). Many Pteromalinae are also large-bodied and can be confused superficially with Trigonoderinae, although they have incomplete notauli.
