Original description as Metriaclima flavicauda:
- Li, Shan & A.F. Konings, J.R. Stauffer. 2016. "A revision of the Pseudotropheus elongatus species group (Teleostei: Cichlidae) with description of a new genus and seven new species". Zootaxa. v. 4168(n. 2), pp. 1-29 (crc07492) (abstract)
Conservation: Metriaclima flavicauda is not evaluated by the international union for the conservation of nature in the iucn red list of threatened species. Although M. flavicauda is rather common at Zimbawe Rock and at the rocky pinnacle near Mumbo Island, these two localities are the only areas of known distribution of this species. The fact that these two places are rather small the species should be listed as vulnerable to extinction.
