Description:
Some Tardigrades were collected during the 1964/1965 R. V. "Meteor" cruise in the Indian Ocean. Thirty-nine specimens were gathered by H. THIEL from deep sea stations ranging from 1630 to 4690 m. These specimens included the types of a new family of Arthrotardigrada: the Coronarctidae, a preliminary description of which was given by RENAUD-MORNANT (1974). A complementary and detailed description of adults and larvae is given hereby and an attempt is made to insert this new family in the phylogenetical series of the order Heterotardigrada. A new genus of Halechiniscidae is established with the description of the type-species Euclavarctus thieli n. g., n. sp. The genus Pleocola CANTACUZÈNE, 1951 is recorded from two different stations and P. conifera n. sp. is described. The problem of the distribution of Tardigrada in abyssal depths is discussed on account of the occurrence of Coronarctus in both Indian Ocean and Atlantic Ocean, and of the new record of the genus Pleocola in deep water.
