Myzotarsa Anaxiphilius, New Genus, New Species, an Atylopsine Amphipod (gammaridea: Pleustidae) Commensal with Lithodid Crabs in California

چکیده
King crabs of the genus Paralithodes are hosts to a new genus and species of commensa! pleustid amphipod off southern California. The dactyls of the walking legs of the amphipod bear a novel structure, a sucker, for adhesion to the host, The new genus is piesiomorphic in many aspects, but aporaorphically modified as a commensal. Most (possibly all) specimens are found on crabs parasitized by the rhizocephalan Briarosaccus caltosus, and the symbiosis seems to involve all three organisms. The new species is the first member of the subfamily Atylopsinae described from the Pacific Ocean. The family Pleustidae and subfamily Atylopsinae are rediagnosed to accommodate
