Taxon classification Animalia Arthrotardigrada Halechiniscidae

Styraconyx sp. Fig. 8

Material examined.

One female adult and one four-clawed juvenile found in sediment sample 4 (Table 1).

Remarks.

The individuals found resemble Styraconyx nanoqsunguak Kristensen & Higgins, 1984 by the dorsal ridges (Fig. 8A, B). However, these specimens are distinguished by the lateral cirrus with no scapus (which is present Styraconyx nanoqsunguak ), longer peduncles of the external digits and leg IV sense organs consisting of a spherical papilla and a distal spine (which is an elongate papilla and a shorter distal spine in Styraconyx nanoqsunguak ). While I believe this is a new undescribed species, lack of visible taxonomic characters has hindered providing a complete species description.
