Current generic position.

Rhiostoma Benson, 1860

Type locality.

Sungei Siput, Perak [Sungai Siput, Kuala Kangsar District, Perak, Malaysia].

Type material.

Lectotype (design. n.) NHMUK 1939.4.13.23 (Fig. 8G).

Remarks.

The original description does not clearly state how many specimens were available to the author. Laidlaw’s use of the term "Type specimen in my collection" does not constitute a valid holotype designation ( ICZN 1999: Art. 73.1.1, 73.2 and Recommendation 73F). The NHM collections hold a lot containing one specimen, NHMUK 1939.4.13.23, with a label in Laidlaw’s handwriting stating the taxon name, collection locality and "From type series". It has subsequent been incorrectly labeled as a “Paratype”. To avoid the assumption of the existence of a holotype ( ICZN 1999: Recommendation 73F), this specimen is here designated as the lectotype to stabilise the name.
