简单描述 型态特徵 | 形态测量图

背的软条 (总数): 15-17; 臀鳍软条: 16 - 17. Diagnosis: This species is distinguished from its congeners by the following combination of unique characters: 15-17 dorsal fin rays; 16-17 anal fin rays; male coloration with irregular red reticulation contrasting with light blue background color on the entire body. The frontal and superior portion of the head red; anal fin with a red distal part. The caudal fin base is red spotted, with distal part transparent light blue. The anterior part of base of dorsal fin has distinct black spots and hardly visible papillae. Sides of female are not marked like the males, but with narrow brown scale margins (Ref. 53985).

Populations of this species have been found scattered over a large area in the Luapula River basin; specimens have been found mainly in shallow and vegetated parts of small, slow-flowing rivers which empty into swamps; the species was also collected from so-called "dembos" or water-filled depressions; all habitats were temporary and only filled with water during the wet season and for a short period afterwards, the bottom substrate of which were usually silt or clay with a high humus content (Ref. 53985).
