最初命名為 Petrotilapia palingnathos:
- Lundeba, Mary & J.R. Stauffer Jr. & A. Konings. 2011. "Five new species of the genus Petrotilapia (Teleostei: Cichlidae), from Lake Malawi, Africa". Ichthyological Explorations of Freshwaters. v. 22(n. 2), pp. 149-168 (crc03458) (摘要)
保育: Petrotilapia palingnathos 被評鑑為國際自然保育聯盟瀕危物種紅皮書名單中的 (LC) 無危 (2018). . Since it lives in close contact with rocks it is unlikely many are caught in fisherman's seines although it would be trapped in gill nets if they were set close to the rocks. In the short term there appears to be no particular threat to the existence of this species.
