简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 17 - 23; 臀鳍软条: 19 - 23; 脊椎骨: 27 - 29. This species belongs to Hypsolebias antenori group but it differs from all other members by having a dark grey to black stripe on the distal margin of the dorsal fin in males (vs. stripe absent). It is similar to H. antenori and H. igneus, and distinguished from the remaining species of the genus, by the presence of a broad orangish red zone on the anal fin in males (vs. red zone absent). It can be diagnosed from H. antenori and H. igneus by having 11 scales in the transverse series (vs. 14) and 11 gill rakers on ventral portion of first branchial arch (vs. 13); from H. antenori by having longer filaments on the anal fin in males, reaching the posterior portion of the caudal fin (vs. reaching basal portion of the caudal fin); and from H. igneus by having 6 pelvic-fin rays (vs. 7) and 27 scales in the longitudinal series (vs. 29-30) (Ref. 94133)
Found in a seasonal pool (Ref. 94133).
