Collembola from lan Mayen, Bj0rn0ya and Hopen with additions to the species list from Spitsbergen. Fauna norv. Ser. B, 31, 69-76. Some new collections from the arctic islands of Norway are reported. 28 species were col lected from lan Mayen, 24 at Bj0rn0ya and 12 at Hopen. The fauna of the islands is domina ted by Holarctic species, of which Hypogastrura sp. near sensilis (Folsom), Wil/emia similis Mills, Folsomia stella Grow & Christiansen and F. taimyrica Martynova are reported for the first time from the European arctic. 1sotomina gracilis Stach, 1962 is transfered to Folsomia and made senior synonym of Folsomia alpha Grow & Christiansen, 1976. Onychiurus ursi n.sp. is described (HolarcticJ and Onychiurus groenlandicus (Tullberg. 1876) is redescribed (HolarcticJ. Several corrections and additions are made to the species list from Spitsbergen, and 47 species are recognised from the island.
