Pupina laffonti Ancey, 1899

Figs 37M , 41D

Pupina laffonti Ancey in Bavay & Dautzenberg, 1899: 51-53, pl. 3, fig. 4, 4a. Type locality: Ile de Poulo Condor [Con Dao Island, Vietnam]. Fischer and Dautzenberg 1904: 431. Fischer-Piette 1950: 167. Wood and Gallichan 2008: 57, pl. 25, figs 4, v.

Type material examined.

Lectotype MNHN-IM-2000-9656 (Figs 37M , 41D ) from Poulo-Condor. Paralectotypes NMW.1955.158.24152 figured in Wood and Gallichan (2008: pl. 25, figs 4, v).

Diagnosis.

Shell fusiform; last whorl ca. 70% of shell height. Suture very shallow. Apertural lip highly thickened but not expanded. Parietal tooth sharp, tooth-like, thickened; columellar tooth fin-shaped, thickened, located next to slit-like anterior canal. Posterior canal gradually widening like keyhole.

Differential diagnosis.

Pupina laffonti is similar to P. anceyi in having a fusiform shell shape with very shallow suture, and a fin-shaped, thickened columellar tooth, located next to slit-like anterior canal, but differs in having a sharp, tooth-like, thickened parietal tooth, and a posterior canal that is gradually widening like keyhole.

Distribution.

Known only from the type locality ( Fischer and Dautzenberg 1904).

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).
