Calohypsibius Thulin 1928

Genus Calohypsibius Thulin, 1928 Calohypsibius Thulin, 1928: 238. DIAGNOSIS. ��� Same as for the family Calohypsibiidae. ETYMOLOGY (NOT PROVIDED IN THE ORIGINAL DESCRIPTION). ��� After Schuster et al. (1980), from Ancient Greek ����^��ς (k��llos) = beauty; derivatives calli-, callo- mean beautiful, pretty. Thulin most likely wanted to highlight the cuticular sculpturing, which is exceptionally complex, rich and unusual among Eutardigrada. COMPOSITION AND REMARKS Currently only three species, namely C. maliki Michalczyk & Kaczmarek, 2005 (Fig. 4 B), C. ornatus (Richters, 1900) (type species; Figs 3 C, D, 4 A), and C. schusteri Nelson & McGlothlin, 1996 (Fig. 4 C), are ascribed to the family. Nevertheless, Barto�� (1940) already described the remarkable variability within European records of the ornatus complex, which raises justifiable concerns as to whether C. ornatus encompasses only a single species. Further, as suggested by Pilato (1998), it is very likely that the genus comprises many more species than currently recognised. However, a systematic integrative study based on extensive sampling is needed to verify this hypothesis.
