Current generic position.

Rhiostoma Benson, 1860

Type locality.

Bukit Chuping, Perlis, Malaysia.

Type material.

Lectotype (design. n.) NHMUK 1938.10.25.1 (Fig. 4C), paralectotypes NMW 1955.158.01101 (3 shells) and NMW.Z 1981.118.02703 (1 shell).

Remarks.

The original description was clearly based on more than one specimen, and included an illustration and one set of shell measurements. There is only one specimen in the NHM type collections with Tomlin’s hand written label stating “Type” and the collection locality. This specimen exactly matches with the illustration (not full adult stage) and the measurements given in the original description and is here designated as the lectotype to stabilise the name. The other two lots of Tomlin collections in the NMW with the label stating “paratype” are therefore considered as paralectotypes.
