Etymology: Australoheros: From the Latin word 'australis' meaning southern, and the name Heros, after the nominotypic genus of the Heroini tribe.
Tribe; acaroides: Name was not explained by Hensel, probably from 'Acara', an Amerindian word used for South American cichlids (historically it was linked as a genus group taxon with Cichlasoma- and Aequidens like species) and '-ioides' from the Greek suffix '-eides', meaning like or similar, in reference to the appearance similar to the species of the genus Acara Heckel, 1840.

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 16 - 17; شعاع نرم باله پشتي (کل) : 8 - 10; خارهاي باله مخرجي: 6 - 8; شعاع نرم باله مخرجي: 7 - 9. Distinguished from all members of the Australoheros forquilha, Australoheros scitulus and Australoheros kaaygua groups by the presence of well developed caudal-fin base spot ( vs. spot absent or weakly developed as a pigment narrow bar); from Australoheros minuano and all the species of the Australoheros facetus group by having a well developed longitudinal stripe (vs. weakly developed) and three abdominal bars vs. four (except in Australoheros guarani; from all the species of Australoheros kaaygua group by the possession of more pectoral rays 14 (vs. 12-13); from Australoheros facetus by its isognathous jaw (vs. prognathous); and from Australoheros facetus and Australoheros guarani by having modally 5 cheek scale rows (vs. three in Australoheros facetus and four in Australoheros guarani) (Ref. 85206).
Body shape (shape guide): short and / or deep.
It occurs in streams with moderate current and with sandy and clayey substratum. During dry season, this species is found in deeper parts of the streams, usually shaded by vegetation. It also inhabits marginal lagoons and flooded regions of great rivers. Can tolerate moderately salt water in some lagoons and estuaries. Diurnal, feeding preferentially on diptera larvae, macrophytes, cladocera, hirudinea and some aquatic ascaris (Ref. 85206).
