Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 11 - 12; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 14 - 16. Scales are cycloid: body and head are entirely scaled, except on ventral surface of head; frontal squamation is of G-type; scales on mid-longitudinal series 27-29 + 2-3 on caudal base (Ref. 57728). Episemion krystallinoron has a unique combination of male color characters: the dorsolateral body color of adult males is metallic blue-green, they have three or four more or less regular horizontal rows of red dots onn sides of body, beginning just behind head, and the unpaired fins contain blue to blue-green dots (Ref. 57728).
Occurs in fast flowing rivers of 4-5 m wide and 0.80-1 m deep; sandy bottoms and no aquatic vegetation; found amongst overhanging terrestrial vegetation (Ref. 57728).
