Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 11 - 12; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 10 - 13. This species is distinguished by the following characters: upper jaw distinctly wider than long; width divided by length 1.05-1.35; sixth anal fin ray of adult males much thickened and enlarged, not reaching base of caudal fin; fourth to seventh dorsal rays of adult males slightly elongate; a prominent dark brown stripe along the midline of the snout.
