Hypsibius Ehrenberg 1848
Hypsibius sp. Material examined: One specimen from site 1, body length 171 µm. Remarks: This single specimen is poorly preserved and oriented so that an adequate description is not possible. But it is remarkable in that only a very small number of marine eutardigrades are known. The genus Halobiotus...

Hypsibius sp. Material examined: One specimen from site 1, body length 171 µm. Remarks: This single specimen is poorly preserved and oriented so that an adequate description is not possible.
