Pupina anceyi Bavay & Dautzenberg, 1899: 53, 54, pl. 3, fig. 5, 5a. Type locality: Entre Lang-Son [Lang Son Province, Vietnam] et That-Khé [That Khe, Lang Son Province, Vietnam]. Fischer and Dautzenberg 1904: 431. Fischer-Piette 1950: 167. Do et al. 2015: 126, fig. 5e, Son La Province, Vietnam.

Pupina (Tylotoechus) anceyi - Kobelt 1902: 306.

Eupupina anceyi - Dautzenberg and Fischer 1908: 207, Mo-Xat [west of Quang Uyen, Cao Bang Province, Vietnam].

Type material examined.

Lectotype MNHN-IM-2000-35833 (Figs 37L , 41C ) from Lang-Son and That-Khé.

Diagnosis.

Shell fusiform; last whorl ca. 65% of shell height. Suture very shallow. Apertural lip highly thickened but not expanded. Parietal tooth triangular, thickened, covering posterior canal, approaching but not extending beyond the outer margin of apertural lip; columellar tooth fin-shaped, thickened, located next to slit-like anterior canal.

Differential diagnosis.

Pupina anceyi is similar to P. laffonti in having a fusiform shell shape with very shallow suture and a fin-shaped, thickened, columellar tooth that is located next to a slit-like anterior canal, but differs in having a triangular, thickened, parietal tooth covering a posterior canal, and the parietal tooth approaching but not extending beyond the outer margin of apertural lip.

Distribution.

Northern Vietnam ( Do et al. 2015).

Remarks.

As the original description did not explicitly state that the description of this species was based on a single specimen (nor could this be inferred), the designation of a holotype by Fischer-Piette (1950) in fact constitutes a lectotype designation ( ICZN 1999: Art. 74.6).
