概要

論文の詳細を見る
A new genus and new species of the thalassinidean shrimp family Axiidae are described and illustrated on the basis of specimens collected from shallow waters of the Boso Peninsula and Sagami Bay, central Japan. Structure of the modified first and second pleopods in male suggests a close relationship of the new monotypic genus, Litoraxius, to Bouvieraxius Sakai and de Saint Laurent, 1989, but several characters, including the lack of pleurobranchs on the thoracic somites, unique structure of the antennal flagellum and the greatly unequal chelipeds immediately distinguish the new genus from the latter. The new species, Litoraxius boshu, seems to be a burrower inhabiting silt stone substrates, although its ecology remains poorly known.
