Marine isopod crustaceans from the St. Paul and Amsterdam Islands, southern Indian Ocean

Abstract

Nineteen species of isopods collected during the cruise MD. 50/Jasus of R/V Marion Dufresne in July 1986, are recorded from the waters around the St. Paul and Amsterdam islands of the southern Indian Ocean, of which 13 are identified to species level. Included are eight species previously recorded from this region. One new genus, Bathylana , and three new species, Bathylana apalpalis, Joeropsis sanctipauli and Metacirolana arnaudi , are described. The asellote Desmosoma longimana (Vanhoeffen) is recorded outside of the Antarctic region for the first time. The species of this collection reaffirm the presence of Antarctic, Subantarctic and southern African elements in the fauna
