Comments on taxonomy, distribution and bionomics.

Among all Middle Asian Raphirus  , Q. umbrinus  is most similar to Q. novus  from which it can be distinguished by the structure of aedeagus: median lobe with distinct ventral tooth near its apex and apical portion slightly curved dorso-ventrally (in lateral view); paramere (underside) with sensory peg setae arranged in wide lateral rows merging at parameral anterior margin.

As a common and widespread species in Europe, Q. umbrinus  was noted and illustrated in numerous papers. The latest summary can be found in Assing & Schülke (2012). Based on Kascheev (1989) and material examined here, Q. umbrinus  occurs in the mountains of southern Kazakhstan where it can be found in leaf litter and dung at elevations up to 1845 m.
