Remarks Males have very fine breeding tubercles sparsely distributed on most of head and trunk but densely aggregated on basal third of pectoral-fin rays, basal quarter of pelvic-fin rays and in a band between bases of pelvic fins; at bases of dorsal-fin rays, on isthmus and on branchiostegal membranes. No significant differences in lengths of paired fins between males and females, though paired fins are more broadly rounded in males (Ref. 94765).

This species is similar to Oxynoemacheilus zagrosesis , but with body with more slender dorsalventral aspect and without a hump, transverse bands on body more regular and well-delimited, posterior processes of bony air-bladder capsule larger and directed posteriorly. This differs from other congeners by the combination of the following characters: complete lateral line; weakly emarginated caudal fin; and the very large processes of bony air-bladder capsule, and the process being triangular in shape and directed posteriorly (Ref. 94765).
