Nothobranchiidae (African rivulines)
Etymology: Aphyosemion: Greek, aphye, -es, sardine, anchovy + Greek, semeion = mark, signal (Ref. 45335).
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
; acqua dolce pelagico; pH range: 5.7 - ?; non migratori; distribuzione batimetrica 0 - ? m. Tropical; 23°C - ?
Africa: known from a limited number of localities between Libreville and Cap Esterias in north-western Gabon (Ref. 80395) and Owendo area south of Libreville in Gabon (Ref. 119374).
Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 50.0 cm TL maschio/sesso non determinato; (Ref. 80395); 40.0 cm TL (female)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 12 - 13; Spine anali: 0; Raggi anali molli: 13 - 15; Vertebre: 24 - 25. Diagnosis: This is a fairly large species of the subgenus Chromaphyosemion, larger than all its congeners with the exception of Aphyosemion riggenbachi, which has the most forward placed dorsal fin (Ref. 41203). It is a strictly blue phenotype with a unique red marking on the sides of the body with the exception of the gill lids, with two conspicuous, mood-dependent dark longitudinal bands, with a red dotted dorsal fin, a flamed caudal fin and an "undrawn" anal fin, except for a thin red submarginal and white marginal band, with longer trapezoidal vertical unpaired fins and a caudal fin with short extracts in the males; the female also shows the alpha-shaped mark, with striking, dark bandages and an anal fin without spots, but without a dark mesh pattern around the scales on the sides of the body (Ref. 41203).
Body shape (shape guide): fusiform / normal; Cross section: oval.
This species is found in clear creeks under forest cover, usually over a sandy soil, in the coastal plain (Ref. 80395).
