marien rifbewoner. Tropical
Western Indian Ocean: Persian Gulf and Gulf of Oman; off the Red Sea coast of Yemen and other islands to the south. Although the type locality was stated to be Reunion and cited by several references as occurring there, it is probably erroneous; the species apparently does not occur in the Mascarenes (Ref. 33390).
