Original description as Haplochromis crocopeplus:
- Greenwood, Peter Humphry & C. D. N. Barel. 1978. "A revision of the Lake Victoria Haplochromis species (Pisces, Cichlidae), Part VIII". Bulletin of the British Museum (Natural History) Zoology Series. vol. 6 (4): pp227-281 (crc01160)
Conservation: Haplochromis crocopeplus is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (CR) critically endangered (2010). No data is available about the real status of this species in the wild, the detritus eaters suffered a lot in Lake Victoria from the introduced Nile perch predation. No specimen has been collected or recorded since 1980, despite efforts, so it seems logical that it is endangered or extinct.
