最初命名為 Petrotilapia xanthos:
- 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 xanthos 被評鑑為國際自然保育聯盟瀕危物種紅皮書名單中的 (NT) 近危 (2018). . It is only found between the irregularly-shaped rocks of Gallireya Reef and fishermen would never ply their nets there fearing that they will get snagged on the sharp edges and points of the rocks. Although P. xanthos is not threatened by overfishing, the population is rather small and should be listed as Vulnerable.
