Pupina (Tylotoechus) mouhoti - Kobelt 1902: 317. Hemmen and Hemmen 2001: 39.

Type material examined.

Possible syntypes NHMUK ex. Cuming coll. (3 shells; Figs 29C, D , 33E ) from Cambodia.

Diagnosis.

Shell ovate-fusiform; last whorl ca. 80% of shell height. Apertural lip slightly thickened and slightly expanded; apertural lip when observed from lateral view almost straight. Columellar tooth curved downward like an earlobe.

Differential diagnosis.

Pupina mouhoti is most similar to P. siamensis and P. vescoi , but different from P. siamensis by a more ovate-fusiform shell shape and a smaller parietal tooth, and differs from P. vescoi by a smaller shell, a shorter spire, a more distinct parietal tooth, and having a columellar tooth curved downward like an earlobe.

Distribution.

Cambodia, Laos, and an uncertain record from Thailand ( Fischer 1891; Kobelt 1902).

Remarks.

No material of this species was found during this survey. The specimens from Srakeo Province mentioned in Morlet (1889) possibly belong to P. siamensis . In addition, some specimens mentioned in Fischer and Dautzenberg (1904) and Saurin (1953) possibly belong to P. peguensis .
