(males). Body compressed, width in predorsal region uniform, about half body depth. Post -dorsal region compressed towards caudal peduncle. Predorsal profile convex. Dorsal -fin base convex. Postdorsal profile slightly concave. Pre -anal profile very convex. Anal -fin base oblique. Post -anal profile concave in females, and almost straight in males. Dorsal fin with semicircular border, located posteriorly to mid-body. Origin of dorsal fin in females on vertical passing through base of third anal - fin ray; in males, origin of dorsal fin posterior to vertical passing through origin of anal fin. Pectoral fin with high insertion in horizontal passing through orbital center. Longest ray reaching about seventh scale in longitudinal series. Pelvic fin small, pointed and not reaching origin of gonopodium in adult males; not reaching origin of anal fin in females. Anal fin of females with straight border. Origin of anal fin of females closer to caudal peduncle than to snout tip. Origin of anal fin of males closer to snout tip than to caudal peduncle. Mouth superior, almost aligned with upper border of pupil.
