背面の脊椎 (合計) : 0; 背鰭 (合計) : 15 - 18; 肛門の骨: 0; 臀鰭: 15 - 18. Diagnosis: Nothobranchius chochamandai belongs to the N. brieni species-group, presenting the diagnostic characters of male colouration for this complex of the caudal and anal fins proximal portion spotted; absence of dark distal margin on dorsal fin; absence of spots on head; and absence of black posterior margin of scales (Ref. 97353). Nothobranchius chochamandai is distinguished from all other species of this complex, with the exception of N. symoensi by an anal fin with a light blue distal margin; distinguished from N. symoensi by a dorsal fin without a light blue distal margin, vs. present, and a caudal fin without dark submarginal band, vs. present; within the N. brieni species-group, N. chochamandai is characterised by the following unique combination of morphometrics: postorbital length 56-60% head length; snout length 16-19% head length; head width 65-69% head depth; caudal peduncle length 135-142% caudal depth (Ref. 97353).
Body shape (shape guide): fusiform / normal.
The type locality was a large ephemeral pool formed in a river bed, as a standing fragment of the seasonal river, at the collecting point about 100 m wide, and about 1.5 m deep at its deepest point; all collecting took place in the same general habitat; most parts of the habitat were heavily overgrown by grass and aquatic vegetation consisted of Nymphea species; water slightly turbid, whereas at shallower parts the bottom of the pool was visible; water temperature around noon 25.3°C, pH 7.30 and it contained 20 ppm of total dissolved solids (Ref. 97353).
