Etymology: Aphyosemion: Greek, aphye, -es, sardine, anchovy + Greek, semeion = mark, signal (Ref. 45335); fellmanni: The new species is named after Emmanuel Fellmann, the collector of the new species; Fellmann made four expeditions to the Republic of the Congo to study killifishes and get a better insight in the distribution of Aphyosemion and Epiplatys species in the southern part of the country (Ref. 119321).
Eponymy: Emmanuel Fellmann is a French aquarist who collected this species in the Congo. [...] (Ref. 128868), visit book page.

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 7 - 9; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 13 - 14; позвонки: 28. Diagnosis: With the exception of Aphyosemion congicum, males of A. fellmanni can be distinguished from all other Aphyosemion species by the wide black margins of the dorsal and caudal fin, up to50% of dorsal fin versus 23% in other species, up to 22% of fin height in caudal fin versus 14% in other species; these margins sometimes seem to be blueish white to grey depending on light incidence, as is also the case in A. congicum (Ref. 119321). Males differ from A. congicum by having many red spots on the flanks versus few red spots, more than 70 versus 30 or less; striped red markings in the caudal fin, versus red spots; red spots on the base of the pectoral fin, versus unspotted pectoral fins; presence of a buccal red band and red pigmented throat, versus unmarked throat; ventral black edge in caudal fin as wide as dorsal edge, versus ventral black edge much wider than dorsal edge; and many stripes or large red spots in anal fin, versus only single or a small number of tiny red spots (Ref. 119321). Although it has narrower dark fin edges, Aphyosemion rectogoense resembles A. fellmanni in colour pattern of sides and anal fin, but the interradial red streaks of the anal fin often forms a broad red band at the anal fin base in A. rectogoense; furthermore the pectoral fins of A. fellmanni are mainly yellow with some red spots at the proximal part of the fin, sometimes forming a horizontal red stripe at about fin centre, whereas pectoral fins of A. rectogoense are mainly red with a yellow or whitish edge (Ref. 119321). The sympatric occurring A. schioetzi sometimes has dark red, not black, fin edges, but these are narrow, less than 23% of dorsal fin height and less than 12% of caudal fin height, and it has no red streaks in the unpaired fins and unspotted pectoral fins (Ref. 119321). Aphyosemion labarrei and A. teugelsi are the only other species of Aphyosemion s.l. of which at least some populations have broad black edges in the caudal fin; these species however can easily be distinguished from A. fellmanni by their robust general appearance and the higher number of dorsal fin rays, 7-9 versus 12-14 in A. labarrei and 10-13 in A. teugelsi (Ref. 119321).
Body shape (shape guide): elongated.
