A new species of annual killifish, Nothobranchius nubaensis, is described based on specimens collected from ephemeral water bodies in central Sudan and south-west Ethiopia. The new species is distinguished from the other members of the Nothobranchius ugandensis species group 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 fins in males with short filamentous rays; pelvic fins short, tips reaching the anus; orange red head with three 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.
