簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 17 - 19; 臀棘: 0; 臀鰭軟條: 17 - 19. Diagnosis: Nothobranchius nubaensis can be distinguished from all other species of the genus by the following combination of characters: 17-19 dorsal fin rays; 17-19 anal fin rays; 29-30 scales in median lateral series; dorsal and anal fin with short filamentous rays in males; pelvic fins short, tips reaching the anus; orange-red head with 3 distinct oblique bars on the operculum; dorsal fin light blue with a pattern of irregular orange-red spots and elongated yellow spots in distal areas; anal fin yellow, light blue at base, with a pattern of orange-red spots; pelvic fins yellow with a pattern of orange-red spots; pectoral fins orange-red with a light blue margin; caudal fin orange-red, with short pale or dark red lines extending from fin base onto fin rays (Ref.82677).
Found in residual pools of seasonal rivers and rainwater filled depressions (Ref. 82677). The present disjunct distribution pattern of Nothobranchius nubaensis can be explained by the dynamics of the changing rain pattern and climatic conditions over the vast plains of central and southern Sudan and south-west Ethiopia (Ref. 82677).
