Taxonomic Remarks
Hensel (1870) described Tetragonopterus aeneus as a new species from Porto Alegre, Southern Brazil, however, it is a junior homonym of that of Günther (1860) whose specimens were taken from Oaxaca, Mexico. Steindachner later listed this as a synonym of T. rutilus Jenyns 1842, along with T. obscurus Hensel 1870. Later, Eigenmann (1921:293) listed T. rutilus, T. aeneus Günther and T. aeneus Hensel as junior synonyms of A. fasciatus Cuvier 1819. The obvious homonymy was obscured when Eigenmann placed T. aeneus of Günther as synonym of Astyanax fasciatus aeneus and that of Hensel as synonym of A. fasciatus fasciatus. Through most of the 20th century T. aeneus remained as synonym of A. fasciatus or has been treated as a species of uncertain status. Some authors maintained the association between T. obscurus and T. aeneus Hensel, and used the former as the valid name. F. de Melo and P. Buckup revalidated and redescribed T. aeneus Hensel to avoid homonymy, and gave the new name Astyanax henseli (Ref. 56653).

鉴别: 除了 A. saguazu 与 A. elachylepis 以外与它的同类区分藉由有第二个细长垂直的肩部斑点 (. vs. 一个肩部的斑点) 它有别于 saguazu ， elachylepis 与 fasciatus 复合种藉由 autapomorphic 有一个间隔的空间齿骨齿, 那是相当细长的, 由于尖头放置接近彼此, 而且藉由在每个齿骨牙齿中有五个尖头的极大.(vs.7个尖头的极大) 有别于 fasciatus ， rutilus 與 elachylepis 藉由有 2- 5, 通常 5, 在顎骨的前緣上的三尖齒 (vs.1- 2個齒, 通常 1, 在顎骨的前緣上).(參考文獻 56653)
