G. Hohmann, November 2000. Diagnosis. (Figs 2-3) Aphyosemion pseudoelegans shows the diagnostic combination of characters for the genus Aphyosemion, which are: preopercular neuromast system with six pores, slender body shape, posterior origin of dor- sal fin, dorsal fin small with less than ten fin rays, extend- ed fin rays at the edges of the caudal fin in males, and fe- males with a well visible reticulation due to dark scale bor- ders. Males of A. pseudoelegans differ from all other Aphyosemion species by a diagnostic combination of colouration characters. Most prominently it differs from all other species except A. congicum (Ahl, 1924) by the almost complete dark red to black dorsal fin versus red dots or stripes on lighter background. It also differs from all other species except A. elegans (Fig. 4) by irregular naiTow vertical red bars, based on confluent dots, on flanks of males. It differs from A. congicum by having an asymmetrical colour pattern of the marginal and submarginal bands in the caudal fin versus colour pattern of dorsal and ventral marginal and submarginal bands symmetrically.
