Discartemon vandermeermohri Benthem Jutting, 1959: 166-168, fig. 9. Type locality: Batu Sok, Pulu Weh, Indonesia. Richardson 1988: 185. Marwoto 2008: 191.

Material examined.

Holotype ZMA 3.59.055 (Fig. 9E). Paratypes ZMA 3.59.056 (2 shells) and RMNH Brandhorst Reg. 387 (1 shell).

Remarks.

Shell thickened, globose-heliciform, with a conical spire and distinct suture. Shell surface with strong transverse ridges; varices present; following whorls regularly coiled. Last whorl rounded and regularly expanded; umbilicus widely open and deep. Aperture triangular; peristome thickened, expanded and reflected. Apertural dentition of one parietal and one columellar lamella (Fig. 9E).

This species differs from Discartemon lemyrei in its smaller shell, widely open umbilicus, triangular aperture, and in having two apertural lamellae. Discartemon vandermeermohri is readily distinguished from Discartemon roebeleni and Discartemon collingei in its having a triangular aperture, and in lacking a basal lamella. Also, Discartemon collingei is slightly axially deflected.
