The first description of kinorhynchs from the Spitsbergen Archipelago (Greenland Sea), with a key to the genus Pycnophyes (Homalorhagida, Kinorhyncha)
Two new species of Kinorhyncha, Pycnophyes spitsbergensis and P. mokievskii, are described and illustrated from muddy sediments of the Greenland Sea, from the Isfjord of the West Spitsbergen Island (78°N) at a depth of 6 m. These are the first kinorhynchs described from Spitsbergen, and are the nort...
