Diagnostic features

Cell II with a variable large dark spot on the dorsal margin ( Fig. 75D , arrow). Cells I and II separated by a constricted septum; forming a geniculate stalk. One to three cells above the appendage basal cell, strongly flattened, inflated, separated by constricted and slightly darkened septa ( Fig. 75D , *). Appendage branched above flat cells.

Distribution and hosts

Only known from the type, on Aploderus (Col. Staphylinidae Oxytelinae ) from Russia.
