Nagy, B., B.R. Watters, P.D.W. van der Merwe, F.P.D. Cotterill & D.U. Bellstedt. 2020. Review of the Nothobranchius ugandensis species group from the inland plateau of eastern Africa with descriptions of six new species (Teleostei: Nothobranchiidae). Ichthyol. Explor. Freshwaters, 30 (1): 49, figs. 16-17. Abstract: The Nothobranchius ugandensis species group from the inland plateau of Kenya, Tanzania and Uganda is reviewed. Members of this group are characterized in males by the combination of characters of a light blue body coloration with red to red-brown scale margins; a frontal part of head red-brown; throat light blue or red; a uniform red or yellow caudal fin; and a light blue or yellow anal fin with red-brown spotted pattern. Six new species are identified, to raise total species richness to eleven. Nothobranchius albertinensis from the Albert Nile drainage in western and north-westem Uganda is characterized by a yellow dorsal fin with stripes in medial part parallel to fin rays; yellow anal fin without markings; and anal fin positioned anterior to dorsal fin. Nothobranchius attenboroughi from the Grumeti and other lesser systems east of Lake Victoria in northern Tanzania is characterized by a light blue anal fin with red-brown dots proximally and medially, and becoming yellow distally with narrow red-brown stripes parallel to fin rays. Nothobranchius hoermanni from the upper Wembere drainage central Tanzania characterized by a red throat, light blue anal fin with red-brown spots and stripes proximally and medially, and with a broad light blue distal zone without markings; pectoral fin hyaline with red-brown stripes parallel to fin rays, and exposed branchiostegal membrane red-brown, with cream distal margin Nothobranchius itigiensis from the uppermost Ruaha drainage and the Bahi Swamp area central Tanzania is characterized by a yellow anal fin with red-brown spots proximally, that merge medially to a pattern parallel to fin rays and are fused distally to form a marginal band Nothobranchius moameensis from the Moame system south of Lake Victoria in northern Tanzania is characterized by a light blue anal fin with red-brown dots proximally and medially, and with light blue or yellow distal zone without markings Nothobranchius venustus from south-western Lake Victoria basin in north-western Tanzania is characterized by a dorsal fin with a narrow light blue sub distal band and a narrow red-brown to black distal band; a light blue anal fin with irregular red-brown stripes perpendicular to fin rays proximally and medially, and orange with red-brown stripes parallel to fin rays in distal zone.
