Two new sinistral species of the genus Satsuma A. Adams, 1868, Satsuma squamigera sp. n. and Satsuma adiriensis sp. n., from southern Taiwan are described. Satsuma squamigera sp. n. is characterized by a microsculpture comprising coarse, irregularly-spaced ridges and dense, easily-dislodged triangular scales on its sinistral shell, an angulated periphery, and partly-opened umbilicus. This species inhabits secondary forests in lowland hills. Satsuma adiriensis sp. n. is characterized by a thin, fragile smooth shell with microsculpture of coarse, loose ridges, a rounded periphery, completely-opened umbilicus, and elongated penial verge formed by two main pilasters. This new species was collected in a mountainous, mid-elevation, broad-leafed forest.
