Conservation: Metriaclima usisyae n\'est pas évalué par l\'Union Internationale pour la Conservation de la Nature dans la Liste rouge des espèces menacées. 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.
