33 Rishetia limborgi (Godwin-Austen, 1920) comb. nov.

Fig. 14 G

Glessula limborgi Godwin-Austen, 1920: 56, 57. Type locality: Tenasserim [Tanintharyi Region, Myanmar].

Type specimen.

Holotype NHMUK 1903.7. 1.3200 [re-registered in error as 1985219] (Fig. 14 G) collected by Limborg ex. Godwin-Austen collection from Tenasserim .

Diagnosis.

Shell elongate, turreted and regularly attenuated; apex rounded; subsequent whorls with fine and equally spaced radial ridges throughout. Suture impressed and whorls flattened. Aperture broadly ovate; columella strong, concave, and truncated.

Distribution.

This species is known only from the type locality and is likely endemic to that region.

Remarks.

Godwin-Austen (1920) clearly states that this taxon was described based on only a single specimen collected by O. Limborg. The original description included only a single set of shell measurements but was without illustration. The NHMUK collections contain the type specimen lot, NHMUK 1903.7. 1.3200 ex. Godwin-Austen ex. O. Limborg consisting of a single shell with an original label stating ‘ Type’. Therefore, we considered this shell as the holotype fixed by monotypy.
