First record of the family Dexaminidae and species Guernea (Prinassus) nordenskioldi in the west Spitsbergen fjords (Svalbard, Greenland Sea)

Three species of dexaminid amphipods are currently known from the Arctic, but none of them have been hitherto recorded in the west Spitsbergen fjords (Svalbard). In 2010, four individuals of dexaminidGuernea (Prinassus) nordenskioldiwere sampled for the first time in the mouth of Isfjorden, a large fjord system located at 78°N. The species was originally described by Hansen (1888) from West Greenland and since then it has been collected in a number of locations showing almost circumarctic distribution. This study represents the first record of the family Dexaminidae and the speciesG. (P.) nordenskioldifrom west Spitsbergen (Greenland Sea).
