Ahl, E. 1928. Description of two new Cyprinodont Fishes from Nigeria. Ann. & Mag. Nat. Hist., 10 (2): 601. Diagnosis: Red spots in variable number on male sides over blue (or yellow) background ; Dorsal and Anal, blue near base with red dots in lines crossing rays (notably near base), followed by plain orange (or green) and a red margin ; Caudal, red-brown innerly with orange distally and a circumcaudal red border (Wildekamp, 1983b) ; the often sympatric annual species Pronothobranchius kiyawensis (in a large sense) and Fundulosoma thierryi are easily separated from adult males Caudal fin : rounded for the former, fan-shaped with upper and lower extensions for the latter (Huber, 2006b) ; distinguished from all congeners by male with about 30-50 dots on sides, each being lesser in diameter than the radius of the pupil, a proximal (basal) band on Anal fin, Ventral fins reaching the genital papillae, Dorsal fin tip reaching Caudal fin, female also with dots on sides, Dorsal fin with 13-15 rays and 27-29 scales in the median lateral series (LL) (Valdesalici, 2013).

Notes

Status specie: Accepted generally. Very few morphological differences with P. seymouri. Much more distant with P.chirioi and P.gambiensis. It should not differ noticeably in the breeding and maintenance conditions of P. seymouri.
