摘要：Arisroplychifes kolymensis (Kiparisova) is investigated and described in detail from collections made at Botneheia, Spitsbergen, where it occurs at the top of the Botneheia Formation (Daonella Shale). It is a rather small species and the stratigraphically highest representative of the genus in Spitsbergen. Its suture line is remarkable by its possession of the additional U,-lobes between the internal lobe and the first umbilical lobe. A lobe of this kind has so far been described only once, with Arcesfes (Proarcesres) bicarinatuc by Schindewolf (1968), which suggests affinities between Ptychitidae and Arcestidae.
