THE TARDIGRADA FAUNA OF HAINAN ISLAND (ASIA: CHINA) WITH DESCRIPTIONS OF TWO NEW SPECIES

A checklist of 26 species of tardigrades from Hainan Island is given in this paper. They belong to two classes, three orders, four families and fi fteen genera. Twenty-three species of tardigrades were found in this present study. Twenty of them are new records for Hainan including seven new records for China and two new to science. Calcarobiotus hainanensis, new species, differs from Calcarobiotus (Calcarobiotus) digeronimoi Pilato, Binda & Lisi, 2004, by the presence of dentate lunulae on hind legs, fi rst macroplacoid drop-shaped instead of rod-shaped and fi rst macroplacoid shorter than the third. It differs from Calcarobiotus imperialis Abe & Takeda, 2000, mainly by lacking lateral spurs on claw basal portion of the hind legs. Minibiotus wuzhishanensis, new species, differs from species with two macroplacoids in the genus Minibiotus mainly by the cuticular sculpture on dorsal side of the body.
