Notes on some tardigrades from Thailand, with descriptions of two new species

Abstract

Three species of tardigrades are reported from Thailand: Pseudechiniscus quadrilobatus Iharos, 1969, Calcarobiotus (Calcarobiotus) digeronimoi sp. n., and Mixibius sutirae sp. n. Calcarobiotus (C.) digeronimoi sp. n. has claws of Calcarobiotus type; those of the first three pairs of legs have a medial and a lateral spur, those of the hind legs lack basal spurs. Mixibius sutirae sp. n. has a densely sculptured dorsal cuticle and two macroplacoids; it lacks lunules and other thickenings on the legs. It is similar to Mixibius ornatus Pilato et al., 2001, from which it differs in characteristics of the cu‐ticular sculpture and by having the ventral surface unsculptured. © The Royal Society of New Zealand 2004.
