A small collection of discinids from Spitsbergen includes two poorly preserved fragments of ventral valves with an incomplete pedicle disc bearing a narrowly trigonal pedicle tract. This element is similar to the type known in Recent discinids. Its general size, comparatively large, is suggestive of a wide embayment of the larval ventral valve. A new species Discinisca spitsbergensis sp. n. is proposed.
