简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 背的软条 (总数): 0; 臀棘 0; 臀鳍软条: 171 - 189; 脊椎骨: 80 - 110. Distinguished from its congeners by the following combination of features: mouth length 5.4-6.4 %HL; postocular distance 36.4-41.0 %HL; pectoral fin length 27.0-35.3 %HL; scales always present above lateral line at anterodorsal region of body, in 11-13 rows above lateral line at midbody; anterior unbranched anal-fin rays 23-28; and a white to yellowish-white (sometimes indistinct) band on frontal portion of head and middorsum; caudal fin with 13-15 rays (Ref. 36352).
在特徵的组合之后与它的同类区分了藉由: 嘴长度 5.4-6.4% HL; 眶后的距离 36.4-41.0% HL; 胸鳍长度 27.0-35.3% HL; 鳞片总是位于之上在身体的前背部区域的侧线, 在 11-13 列中在身体中央是在侧联机面; 前面的不分枝的臀鳍棘条 23-28; 而且在头部与背面中央的前部分上的一条白色到黄白色 (有时不明显的) 条纹; 尾鳍有 13-15个鳍条。 (参考文献 36352)

生物学特性     字汇 (例如 epibenthic)

Collected from caves within the São Domingos karst region in the upper portions of the Rio Tocantins basin. The species occur in both subterranean and surface drainages and appears to be well adapted to epigean habitats as indicated by the overall condition and sexual maturity of the individuals from cave habitats (Ref. 84053).
