Scientific Name:	Haplochromis cyaneus
Species Authority:	Seehausen, Bouton & Zwennes, 1998 [nom. inval.]
Taxonomic Notes:	Medium sized species with steep, moderately convex dorsal head profile, small mouth, forcep like dentition and a conspicuous melanin pattern of longitudinal stripes and vertical bars. Pronounced sexual dimorphism in colouration and head length. The name of this species is objectively invalid; preoccupied by Haplochromis cyaneus Trewavas 1935, which is treated as a synonym of Copadichromis cyaneus.

Assessment Information [top]

Red List Category & Criteria:	Endangered   B1ab(iii)+2ab(iii)   ver 3.1
Year Assessed:	2006
Assessor/s:	Bayona, J.D.R.
Reviewer/s:	Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Programme)
Justification: Distributed in very few locations (less than five) and extent of occurrence <5,000 km². Habitat quality and quantity are declining due to eutrophication and increased turbidity.

Geographic Range [top]

Range Description:	Distributed across three islands in south eastern Lake Victoria: Chamagati (Sengerema Region), Makobe (South Western Speke gulf), and Nansio (Ukerewe). Thought to be absent from other areas of the lake.
