Description of a new species of the genus Trichopeltarion A. Milne-Edwards, 1880 (Decapoda: Brachyura: Trichopeltariidae) from western Pacific and southeast Asian waters

摘要

The present study limits the distribution of a deep-sea crab, Trichopeltarion ovale Anderson, 1896, to the Indian Ocean, and describes a new species of what has been referred to as T. ovale from the western Pacific and southeast Asia. Trichopeltarion danieleae sp. nov. differs morphologically from allied congeners by a combination of characters of the carapace and ambulatory legs. The new species is also distinguished from two fossil Trichopeltarion species, T. huziokai (Imaizumi, 1951) and T. inflatus (Kato, 1996).
