Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 16 - 17; Épines anales: 0; Rayons mous anaux: 17 - 18. Diagnosis: Nothobranchius balamaensis is distinguished from all other members of the genus, except N. kirki, by the following unique combination of characters in males; body colouration bright iridescent light blue, with narrow brown-red to orange scale margins creating an irregular reticulated pattern; anal and caudal fins overall orange, darker in basal and proximal zones, grading through medial zone to lighter orange in distal zone and devoid of distinctive markings or banding; dorsal fin with marbled pattern in proximal region comprising irregular brown-red markings on yellow-orange background, distinct striated pattern parallel to fin rays in medial and distal zones with inter-ray membrane distinctive black between first 4-5 rays; anal fin shape mildly trapezoidal (Ref. 127332). Nothobranchius balamaensis differs from the closely related and most similar N. kirki by some elements of male colour pattern: anal fin devoid of markings or banding in proximal zone, vs. narrow light blue to white proximal band or series of irregular markings in N. kirki; dorsal fin with marbled proximal zone and prominently striated medial and distal zones, vs. marbled or vermicular pattern throughout proximal and medial zones with only a hint of striation pattern in distal zone of some specimens (Ref. 127332).
Found in pool in a seasonal stream course, less than 1 m in depth, with turbid and slow flowing water; riverbanks were covered by grass with remnants of Miombo vegetation (Ref. 127332).
