can be distinguished by the depressed spire, yellowish colour, large and rounded last whorl, and a wide and deep-channelled suture. The genitalia have long penis and vagina, one circle of coiled epiphallic caecum and a small dart apparatus located at the base of the vagina opposite the penis. Spermatophore has three spines at the proximal end and a cluster of small spines at the distal end of the tail filament.
