Host: Pachynematus clitellatus (SERVILLE, 1823) (Hym. Tenthredinidae ) (ZSM).

D i s t r i b u t i o n: West Palaearctic, studied material from Bulgaria *, Germany and Sweden.

Taxonomical remarks: This species was transferred to Scopesus (recte: Scopesis ) by THOMSON (1894) and included in this genus by all following authors. It differs from Scopesis by a shorter 1 st flagellar segment in relation to the 2 nd segment and the presence of a latero-median carina in the basal half of 1 st tergite. The clypeus is moderately convex and bulging medially. We transfer this species to the genus Campodorus here (nov.comb.)
