Etymology: Bryconaethiops: Greek, bryko = to bite+ Aethiops, region in North east Africa (Ref. 45335).
More on author: Günther.
Taxonomic Remarks
The synonym Bryconaethiops yseuxi is revalidated (Ref. 74421).
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
; acqua dolce pelagico; pH range: 6.0 - 7.5; dH range: 8 - 18. Tropical; 24°C - 28°C (Ref. 2060)
Africa: Ogowe (Ref. 5331, 80290), Nyong, Lobé, Ntem, Kouilou basins and in Nkomi lagoon (Ref. 80290). Also in the lower, middle (Ref. 80290) and upper (Ref. 5331) Congo and the Malagarasi (Ref. 54847). Reports from Lake Kivu (Ref. 5331, 80290) are based on an erroneous locality interpretation whereby the Kivu Province was mistaken for Lake Kivu (Ref. 46152).
Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 17.2 cm SL maschio/sesso non determinato; (Ref. 74421)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 10; Spine anali: 0; Raggi anali molli: 18 - 23. Diagnosis: 6.5-7.5 scales in transverse row between lateral line and dorsal fin origin; 12 scales around caudal peduncle (Ref. 74421, 80290); 35-40 (Ref. 80290) or 34-41 (Ref. 74421) lateral line scales. Eye diameter/head length 26-40% (Ref. 80290) or 31.4-43.8 (Ref. 74421). 15-20 (Ref. 80290) or 17-19 (Ref. 74421) anal fin branched rays.
Body shape (shape guide): fusiform / normal.
Affinities: similar to B. macrops but with a higher number of scales around caudal peduncle and a smaller eye (Ref. 80290).
