Remarks Males usually possess 7-11 vertical flank-bars, their dorsal, anal, caudal, pelvic and pectoral fins are white but with a dark pigmentation on the base of the 1st-4th dorsal rays (vs. 7-9 dark circular blotches on their flanks, starting behind the operculum and extending until the base of the caudal fin in females, similar to the males, their dorsal, anal, caudal, pelvic and pectoral fins are white). Both males and females display a yellowish dorso-posterior part of the eyes.

Diagnosis

Distinguished from all other species of Aphanius by the following combination of characters: completely without scales; caudal fin slightly forked; males with dark pigmentation at the base of the four anterior dorsal rays; single row of tricuspid teeth with the two lateral cusps shorter than the middle one; rounded otolith with short rostrum and antirostrum of almost equal length; reduction in biomineralization of caudal skeleton such as thin epural bone; 157 (vs. A. dispar) and 170 (vs. A. ginaonis) molecular characters in the 12S mt-DNA and tRNA-Val (Ref. 96446).

Description: males with 9-12 and females with 9-11 dorsal-fin rays; males and females with 9-11 anal-fin rays; males with 12-15 and females with 13-15 pectoral-fin rays; males and females with 5-6 pelvic-fin rays; males with 12-16 and females with 14-16 gill rakers (Ref. 96446).
