Taxonomic study of the Kinorhyncha in Japan. II. Condyloderes setoensis, a new species (Kinorhyncha: Cyclorhagida) from Tanabe Bay (Honshu)-first representative of the genus in the Pacific Ocean

摘要

A new species of centroderid kinorhynchs, Condyloderes setoensis, new species, from muddy sediment at Tanabe Bay, Honshu Island, is described and illustrated using light and electron microscopy. Previously, members of the genus Condyloderes were found on the coasts of Scotland and the Netherlands in the North Sea (Condyloderes multispinosus), and the coast of India in the Bengal Bay (C. paradoxus). Condyloderes setoensis is the third species of the genus Condyloderes and the first representative of the genus in the Pacific ocean. A key to the three species of the genus is proposed. The genus Condyloderes is the fifth genus of the Kinorhyncha known from Japan and the ninth genus known from the Pacific.
