Geographic Range [top]
Range Description: According to the systematic revision of Köhler and Glaubrecht (2006), the only confirmed information on this species comes from the type material, which came from Raheng, Siam (believed to be in Tak Province, Thailand), but the species has not been relocated since. Reports from northern Viet Nam (Thai Nguyen Province, Bac Ninh Province, Bac Can Province, the Chay River (Lao Cai and Yen Bai provinces), Lo and Gam rivers (Ha Giang and Tuyen Quang provinces), Hong, Ma and Chu rivers (Thanh Hoa Province), Nghe An Province (Lam River), and Ha Tinh Province), and from northeastern Lao PDR (Dang and Ho 2007), are considered erroneous. They probably refer to misidentified specimens of Sulcospira tonkiniana (widespread in northern Viet Nam) and potentially Brotia mariae (central-northern Lao PDR).
