Pseudechiniscus asper, a new Tardigrada from Hokkaido, northern Japan



Pseudechiniscus asper, a new Tardigrada from Hokkaido, northern Japan



Proceedings of the Biological Society of Washington 111(4): 843-848, Dec 23



A new semi-terrestrial tardigrade species of the family Echiniscidae, Pseudechiniscus asper, is described from a single male collected from Hokkaido, northern Japan. This species can be readily distinguished from the known congeners by a combination of the following characters: almost the entire surface of all dorsal plates is covered with coarse cuticular granulation; the subtriangular projection is present at position D; paired lobes on pseudosegmental plate are roundly triangular and tipped with papillate projection; and, each internal claw is armed with a spur.
