The Genus Amblyops (Crustacea: Mysida: Mysidae: Erythropinae) from East Asia and Australia, with Descriptions of Ten New Species

Abstract

Ten new species of the genus Amblyops (Crustacea: Mysida: Mysidae: Erythropinae) from waters neighboring East Asia and Australia, mainly Japanese waters, are described. The newly established species are A. amamiensis, A. australiensis, A. izuensis, A. kashimensis, A. manazuruensis, A. okinawensis, A. pacificus, A. sagamiensis, A. surugensis, and A. timorensis, bringing the total number of species in this genus to 22. Amblyops pacificus sp. nov. has been reported from the northern North Pacific under the name A. abbreviatus (G. O. Sars, 1869). It is instituted herein as a new species because it differs distinctly from that otherwise northern North Atlantic species in the characters of the eyeplates, antennal scale, and telson. In addition to these 10 new species, four unidentified species are also mentioned. A key to all the named species of Amblyops is given.
