最初命名為 Petrotilapia chrysos:
- Stauffer, Jay Richard Jr. & E. S. Van Snik. 1996. "New species of Petrotilapia (Teleostei: Cichlidae) from Lake Malawi, Africa". Copeia. pp. 695-702 (crc00156)
保育: Petrotilapia chrysos 被評鑑為國際自然保育聯盟瀕危物種紅皮書名單中的 (VU) 易危的 (2006). The listing as vulnerable is caused by the fact that initially it was thought that P. chrysos is restricted to the two small islands in the southeastern arm of the lake, but since it appears to have a much wider distribution I would not regard this species at any type of risk of extinction.
