Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 7; Mjukstrålar i ryggfenan (totalt): 9-10; Taggstrålar i analfenan 1; Mjukstrålar i analfenan: 8 - 9. Distinguished from all other members of the genus by the following combination of characters: 8-9 anal rays; dorsal fins with VI - I,9-10 rays; first dorsal fin with a diagonal black band; females with a thin dark band crossing the chin; juvenile females with a triangular dark patch in region of isthmus; orange pigmentation on dorsal surface of body, and caudal and pectoral fin bases in both juveniles and adults; light blue or turquoise mottling on the head, nape and dorsal surface; sexually dimorphic head morphology (% HL), head lengths similar, males with 5% greater eye diameter and 30% greater lower jaw length, females with 5% greater snout length, 7% greater post orbital length and 6 % greater head width; sexually dimorphic fin morphology (% SL), males with 5% larger first dorsal fin base and females with 7% larger pectoral and 5 % larger pelvic fins (Ref. 55545).
Seems to prefer shallow and clear water riffles with slow or moderate current speed and with a substrate of small boulders and gravel (Ref. 55545).
