Diagnosis.

Shell ovate to fusiform; last whorl ca. 70-75% of shell height. Apertural lip thickened to highly thickened but not expanded. Parietal tooth thickened, fin-shaped or tooth-like, always located next to but not covering posterior canal; columellar tooth fin-shaped, thickened, located next to anterior canal. Posterior canal slightly bulging outward.

Differential diagnosis.

P. aureola is most similar to P. stoliczkai sp. nov. in shell shape and having both fin-shaped and highly thickened parietal and columellar teeth located next to their respective canals; the posterior canal slightly bulges outward. However, P. aureola does not have a furrow between inner and outer peristomes.

Distribution.

Malaysia and southern Thailand ( Maassen 2001).

Remarks.

This species has high variation in shell shape from ovate to fusiform, and the parietal tooth varies from fin-shaped to tooth-like. Despite those shell variations, we assign these shell morphs to P. aureola due to the uniform position of a parietal tooth that is always located next to the posterior canal, and a columellar tooth that is always fin-shaped and not extending over the apertural lip.

By comparing with the possible type specimen, the specimen of P. arula perakensis figured in Foon et al. (2017: fig. 15c) from Gunung Datok Plot, Ipoh, Perak should belong to P. aureola (Foon, pers. comm.).
