> Cichliformes (Cichlids, convict blennies) > Cichlidae (Cichlids) > Geophaginae
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..

Spine dorsali (totale): 15 - 16; Raggi dorsali molli (totale): 6-7; Spine anali 3; Raggi anali molli: 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.

Bayesian length-weight: a=0.00724 (0.00282 - 0.01861), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
