DEEP-SEA SPIDER CRABS OF THE GENUS OXYPLEURODON MIERS, 1885 (DECAPODA, BRACHYURA, MAJOIDEA, EPIALTIDAE), FROM THE NAN HAI 2014 CRUISE IN THE SOUTH CHINA SEA, WITH A DESCRIPTION OF A NEW SPECIES

摘要

During a recent expedition in the South China Sea, three species of the deep-sea epialtid genus Oxypleurodon Miers, 1885 were collected. Two species, O. stimpsoni Miers, 1886, and O. auritum (Rathbun, 1916), are new records for the area. The third species, one of the largest known Oxypleurodon species, is described here as new. It is most similar to O. luzonicum (Rathbun, 1916) and O. sanctaeclausi Richer de Forges & Ng, 2009, in possessing a rounded cardiac plate, but can be separated by the structures of the branchial and pseudorostral spines.
