A NEW MARINE TARDIGRADE, BATILLIPES-CRASSIPES SP-NOV, FROM THE JAPAN SEA (TARDIGRADA, ARTHROTARDIGRADA, BATILLIPEDIDAE)

This paper contains the description of a new marine Arthrotardigrada Batillipes crassipes sp.nov., living in the sand of the supralittoral zone of Furughelm Island (Peter the Great Bay, Japan Sea). The characteristic features of the new species are: broadened femurs on legs IV, undivided clavae, the location of cirrus E at the level of leg IV and the absence of pairs of smooth lateral projections at this level. Both B. gilmartini and B. pennaki have a type of legs IV similar to that of B. crassipess, but they have smooth lateral projections of the body at level of legs IV.
