Aphyosemion Cyanoflavum
📖 Overview
Known from the type locality where it is found syntopic with Aphyosemion coeleste and A. mandoroense, where they occur in more or less similar microhabitats .
🔬 Taxonomy
🐟 Physical Description
Dorsal spines (total): 0; Dorsal soft rays (total): 11 - 12; Anal spines: 0; Anal soft rays: 14 - 15. Diagnosis: Aphyosemion cyanoflavum is a member of the Aphyosemion ogoense group based on DNA analysis . It can be distinguished from all other Aphyosemion species by its cephalic lateral line system, having unique large, dark coloured anterior supra-orbital neuromasts in very wide supra-orbital grooves, 18.3-19.4% of inter-orbital width vs. 7.3-16.9% in other species; very large pre- and postorbital canals with large pores and frontal neuromasts housed in one pit with one anterior lobe; by its wide upper jaw, due to enlarged lacrimal bones, wider than inter-orbital distance versus narrower in all other species, making the dorsal and lateral view of the head much more remniscent of an Epiplatys than an Aphyosemion . Males are distinguished from all other Aphyosemion species by their unique lateral colour pattern: anterior part of body on side yellow and posterior side of body purple-grey; the transition between yellow and purple-grey is very sharp and situated just behind the pelvic fin . Males are distinguished from all other members of the A. ogoense group, except for A. caudofasciatum, A. pyrophore, and A. thysi, by the presence of narrow dark red bars in the posterior part of the flanks and on the caudal peduncle; males are distinguished from the latter three species by the above mentioned wide supra-orbital grooves and the unique colour pattern of anterior yellow and posterior purple grey on the flanks .Cross section: oval.
