Nothobranchius kadleci has light blue body colour but that, depending on the extent of the red-brown scale margins, can appear more or less red. Dorsal, anal and caudal fins are red-brown with irregular white dots and lines.

It is distinguished from the similar N. furzeri by: in males - the smaller depths of the dorsal and anal fins;  the presence of red colour on the gill membrane and lips; red pectoral fins; absence of a black marginal band on caudal fin, and a greater amount of red on the caudal and dorsal fins and on the body; in females - a larger preanal distance. (after Reichard, 2010).

Subgenus: Nothobranchius s.s.

Species group: N. orthonotus group

Nothobranchius kadleci was established as a species by Reichard in 2010, and that status has been accorded by all authors since.

Mozambique: temporary pool about 100 m from the main EN1 national road, not connected to any permanent river system, Sofala Province, (20°41.3'S, 34°06.4'E).

This species is endemic to seasonal freshwater habitats in central coastal Mozambique. It is known from temporary pools and marshes in the drainages of the Save, Gorongose, Pungwe and Zangue rivers, in central Mozambique.
