Conservation: Metriaclima usisyae is not evaluated by the international union for the conservation of nature in the iucn red list of threatened species. Although M. usisyae is rather common at Mara Rocks and on Tchinga Reef, 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.
