Diagnosis. Pincerna vanbuensis is characterised by a small sized, globular shell with irregular, clearly visible ribs on R3.
Distribution. This species is known from Vietnam (SƠn La, Hòa Bình, Quang Ninh, Ninh Binh Provinces) and Laos (Luang Namtha and Luang Phrabang Provinces) ( Vermeulen & Maassen, 2003; Inkhavilay et al., 2019).
Remarks. Its type locality Van-bu most probably refers to “Vạn Bú” Province, which was established in 1895 and remained until 1904. This species clearly differs from P. anceyi and P. costulosa because its R2 is relatively long, while its R1 possesses clearly visible and regular spaced ribs. The operculum of three specimens have been examined. The inner surface of operculum is smooth, glossy and has no central nipple. The outer surface is relatively flat, with indistinct appressed multilamellae. Pincerna vanbuensis is a very variable species in terms of shell size, sculpture of R1 and R3, number of R2 ribs and the extension of the columella (see Tables 1, 2).
