最初命名為 Petrotilapia microgalana:
- Ruffing, Renea A & Angela Lambert & Jay R. Stauffer. 2006. "Description of a new species of Petrotilapia (Teleostei: Cichlidae), from Lake Malawi, Africa". Proceedings of the Biological Society of Washington. 119(4);534–539. 2006 (crc01364)
保育: Petrotilapia microgalana 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 Petrotilapia microgalana lives in close contact with rocks it is unlikely many are caught in fisherman's nets although it would be trapped in gill nets if they were set at greater depth than they are usually employed. For the foreseeable future their appears to be no particular threat to the existence of this species.
