Antenna inserted above lower ocular line; antennal protuberance small; scrobes shallow (Fig. 33 ). Pronotum short with collar not carinate (Fig. 39 ); notauli not complete (Fig. 39 ); prepectus longer than tegula. Mesoscutum and scutellum flat (Fig. 34 ).

Remarks.

This is a small, poorly represented genus, previously found only in the Czech Republic and Sweden ( Hedqvist 1974; Bouček and Rasplus 1991) and recorded here for the first time for the East Palaearctic. The original descriptions of the genus and species are incomplete, and high-quality illustrations have not been published.
