Soft rays of dorsal and anal fin are longer in mature males, and sometimes the vermillion margin of the dorsal fin is thickened with reduced (but not closed) notches. Pelvic fins of males usually longer than those of females, reaching anus or genital papilla, and this difference is more pronounced in larger specimens, dorsal and anal fins pointed in males and rounded in females. Standard length and snout length are larger in males, while iris diameter, head length, predorsal length, prepelvic and preanal length are smaller in males. Males with one urogenital opening, females with 2 separate urinary and genital pores.</p><p><i>Meristic characters</i>: D: XVI–XIV 11–13, A: III 9–10, P: 13–14, V: 5, LS: 27–30, TV: 28–29.</p><p><i>Distribution</i>: Tigris basin (Fig. 469).
