Four species of Ancistrolepis and one of Clinopegma are newly obtained and described from Plio-Pleistocene strata in the Japan Sea borderland : Ancistrolepis masudaensis Nomura, A. grammatus (Dall), A. sp. aff. A. hikidai (Kuroda), A. sp. and Clinopegma borealis Tiba. Among the ten species of Plio-Pleistocene Ancistrolepidinae, A. masudaensis. A. peulepsis, A. koyamai and C. fragilis are extinct. The first three species belong to the Ancistrolepis eucosmius group now living in the eastern North Pacific. They suffered extinction during the late Pleistocene cold-climate maxima because of their distribution being restricted to the Japan Sea borderland. On the other hand, in addition to occurring in the Plio-Pleistocene in the Japan Sea borderland, A. grammatus, C. borealis and Bathyancistrolepis trochoideus Dall survive in the Okhotsk and Bering Seas as well as in the subarctic Pacific Ocean. Recent higher water temperatures and a shallower sill depth may prevent the above three species from migrating back into the Japan Sea.
