Distribution.

This species is known from several localities in Shan State ( Páll-Gergely et al. 2023).

Remarks.

Although this species was described from northern Thailand in Chiang Mai Province, subsequent revision by Páll-Gergely et al. (2023) has expanded its distribution to several localities in southern China, Laos, Myanmar, Vietnam and several additional localities in Thailand. It is considered one of the most widely distributed species, with a range spanning several hundred kilometres ( Páll-Gergely et al. 2023).

The unique shell of this species is slightly concave-conical, bears a subquadrate aperture, lacking apertural dentitions, and shows a weakly elevated parietal wall.
