Material examined

Neotype of Teleas semistriatus Nees

[ AUSTRIA] • 1 ♀ (right of pin); NHMW-HYM#0006904 .

Syntypes of Telenomus nomas Förster

[ SWITZERLAND] • 6 ♀♀; NHMW-HYM#0005390 • 1 ♂; NHMW-HYM#0005392 .

Remarks

The female specimen of Trissolcus semistriatus to the left of the pin was designated as a “paraneotype” by Szabó (1976), an invalid designation. Two additional minuten pins on the same cork have lost their specimens. Telenomus nomas ( Fig. 5 ) clearly belongs to Trissolcus based on the 5-merous clava, T2 wider than long, and presence of the subacropleural sulcus ( Talamas et al. 2017). It was identified to species using the keys in Talamas et al. (2017) and Tortorici et al. (2019). A7 with two papillary sensilla ( Fig. 5A ), complete netrion sulcus ( Fig. 5A ) and the smooth mesoscutal humeral sulcus ( Fig. 5B ) are diagnostic characters that place this species as a junior synonym of Tr. semistriatus .
