Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 13 - 15; Mjukstrålar i ryggfenan (totalt) : 9 - 11; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 8 - 10. This species is distinguished from its congeners, except G. gymnogenysgymnogenys by its more elongate body (body depth 34.9-38.3% SL, mean = 36.7 vs. 38.6-44.2 % SL, mean = 40.6 in gymnogenys specimens larger than 6.5 cm SL), and by the continuous iridescent olivaceous coloration of males (vs. clearly demarcated iridescent blue spots on the center of each scale) (Ref. 118066).
