A new species of camaenid land snail, Satsuma longkiauwensis sp. nov. from southern Taiwan is established. This large
terrestrial and herbivorous snail inhabits the lowland forests with a narrow geographical distribution. The species is characterized
by having a large shell, roundly angulated peripheries adjacent to the peristome, an open umbilicus, a robust
flagellum, a weak expansion on male genitalia instead of a penial caecum externally and a hemispherical verge instead of
an elongated pilaster internally. A key is provided for the first time to identify camaenids from Taiwan.
