Description

Four new species of the freshwater snail in the genus Semisulcospira are described from the early Pleistocene Gamo Formation and the late Pliocene Ayama and Koka Formations of the Kobiwako Group in central Japan. These four new species belong to the subgenus Biwamelania. Semisulcospira (Biwamelania) reticulataformis, sp. nov., Semisulcospira (Biwamelania) nojirina, sp. nov., Semisulcospira (Biwamelania) gamoensis, sp. nov., and Semisulcospira (Biwamelania) tagaensis, sp. nov. are newly described herein. The authorship of Biwamelania is attributed to Matsuoka and Nakamura (1981) and Melania niponica Smith, 1876, is designated as the type species of Biwamelania by Matsuoka and Nakamura (1981).
