Tricolas fuscus Szelényi, 1981a: 401 .

Material examined ( HNHM). Holotype (♀): “Hortobágy Újszentmargita védett erdö Kopogtatás 1974.V.7-10 leg. Draskovits. ” / “Hym. Typ. No. 6820 Mus. Budapest.”

Remarks. Tricolas fuscus was described in the poorly known and now monospecific genus Tricolas Bouček , but lacks most of the distinctive features of that genus, especially those of the propodeum ( Bouček & Rasplus 1991). Instead, it belongs in Mesopolobus Westwood. Its body shape, color, and slightly distinct mesoscutal setiferous punctures suggest it is a member of the Mesopolobus dubius (Walker) species group and therefore an association with cynipid galls is indicated. Within this group, M. fuscus keys to Mesopolobus xanthocerus (Thomson) in Graham (1969) because of its short mesosoma and yellowish antennae ( Figs 32, 36). I hesitate to synonymize M. fuscus under M. xanthocerus , as I have not seen the lectotype of M. xanthocerus . Attempts to contact the Lund University Zoological Museum in order to examine the lectotype of M. xanthocerus were unsuccessful.
