Etymology: Andromakhe: Named for Áνδρομάχη, Andromakhe (‘battle of men’), a character in Greek mythology, she is the wife of Hector, Prince of Troy, and, in Homer’s epic poem Iliad, the mother of Ἀστυάναξ, Astyanax (‘city protector’); tupi: The specific name tupi honors aborigines that lives in northern Argentina.
Eponymy: Andromakhe (or Andromache) is a character in Greek mythology: the wife of Hector, Prince of Troy, and the mother of Astyanax. The name was chosen when the authors placed several species formerly in the genus Astyanax into this new genus. The Tupi are a tribe of people in the type locality of Chapada, Brazil.

背的软条 (总数) : 13; 脊椎骨: 35. Differs from other species of the genus by the combination of the following characters: long pectoral fins always surpassing pelvic-fin origin; anal fin origin at level of a vertical through fifth or sixth dorsal fin rays; one supraopercular and two humeral spots on flanks; two or three maxillary teeth; 35-38 perforated scales in the lateral series; and 24-27 branched anal fin rays. Distinguishes further from most of its congeners by having deep body (36.9-42.6% SL); large eye (10.2-11.9% SL); maxillary length, 100.0-136.6% interorbital width); and presence of 24-25 gill rakers on first branchial arch (Ref. 55798).
有别于其他本属的种藉由下列特征的组合: 长的胸鳍总是胜过的腹鳍起点; 在水平的臀鳍起源一垂直的经过第五的或第六个背鳍鳍条; 一鳃盖上方的与在侧面上的二个肩部的斑点; 二或三个上颚齿; 在侧线列中的 35-38个有排孔的鳞片; 而且 24-27个分枝的臀鳍棘条。 区别进一步从大部分的它的同类借着具有深的身体 (36.9-42.6% SL); 大的眼 (10.2-11.9% SL); 上颌骨长度, 100.0-136.6% 眼间骨宽度); 而且在第一个鳃弓上有 24-25个鳃耙.(参考文献 55798)
