Diagnosis.

A species of Omobrachyiulus differing from congeners by the following combination of opisthomere characters: basoposterior process in the shape of a strongly pronounced lobe forming a nearly right-angled corner at base, ending with a simple and smooth apical outgrowth with a blunt tip; anterior process shaped as a stout spine; mesomeroidal lobe strongly pronounced; solenomere simple, bent strongly caudad.

Previous records from the Caucasus.

Russia, Karachay-Cherkess Republic, by Bolshoy Zelenchuk River (type locality), "Post Akssaut" [probably on Aksaut River] (Lohmander 1936); Kabardino-Balkar Republic, Bisinghi [Bezengi] Valley (Vagalinski and Lazányi 2018).

General distribution.

GRCA.
