Etymology: Dicrossus: Greek, di = two + Greek, krossoi = tassel (Ref. 45335); foirni: Named for Federacão das Organizações Indígenas do Rio Negro, officially abbreviated as FOIRN. This acknowledges FOIRN for giving repeatedly permission to travel on the tribal land of the village communities of different indigenous groups in the middle and upper Rio Negro and its affluent rivers, as well as for carrying out observations on wildlife, especially insects and fish, in these areas. This permitted the observation and collection of this new species.
Eponymy: This is an acronym referring to Federacão das Organizações Indígenas do Rio Negro, officially abbreviated as FOIRN. [...] (Ref. 128868), visit book page.

Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 15 - 16; Μαλακές ραχιαίες ακτίνες (συνολικά) : 6 - 7; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 6 - 7. Can be distinguished readily by having three rows of round to vertical-ovoid, alternating dark grey to blackish, double or triple spots on the sides of the body; adult males with a black spot on the dorsum and basal part of the dorsal fin at the position of hard rays 7 to 8, and a pointed rhombic caudal fin. Exhibits pronounced sexual size and color dimorphism (Ref. 85095).
Inhabits all types of water. Juveniles occur exclusively in very soft and acid, clear and black water while sub-adults occur in whitewater brooks (Ref. 85095).
