Abstract
In a collection of hermit crabs from supralittoral, intertidal, and shallow subtidal areas of the Mascarene islands of Mauritius and Rodrigues (latitudes 19-degrees40'-20-degrees32'S, longitudes 57-degrees18'-63-degrees30'E), 18 species belonging to the genera Coenobita, Calcinus, Clibanarius, Dardanus, Diogenes, and Pagurixus were found. This hermit fauna was primarily composed of species widely distributed within the western Indian Ocean; however a few were previously known only from a few localities. Calcinus haigae Wooster, Clibanarius humilis Dana, C. demani Buitendijk, Diogenes cf. serenei Forest, and Pagurixus cf. tweediei (Forest) are recorded for the first time in the western Indian Ocean, and a new species, Calcinus vanninii, is described and illustrated. The species composition from these islands is discussed and compared with lists previously compiled for two proximate island systems, the Seychelles and Madagascar. As shown by a clustering technique, these latter islands have a closer faunal similarity to each other than to the Mascarenes.File | Dimensione | Formato | |
