Hypselostoma benetuitum Vermeulen et al., 2019 Fig. 7E, F View Figure 7

Hypselostoma benetuitum Vermeulen et al., 2019b: 32, 33, figs 64, 65. Type locality: Phnom Kampong Trach, Kampong Trach area, Kampot Province, Cambodia.

Material examined.

Locality no. 11: CUMZ-CM061 (6 shells; Fig. 7E View Figure 7 ). Locality no. 17: CUMZ-CM081 (19 shells; Fig. 7F View Figure 7 ). The snails were found to live on limestone wall syntopically with Georissa spp.

Distribution.

Kampong Trach area, Kampot Province, Cambodia ( Vermeulen et al. 2019b).

Remarks.

The specimens from the type locality (locality no. 11; Fig. 7E View Figure 7 ) agree well with the drawing by Vermeulen et al. (2019b). This species tends to have a much smaller shell size and be less abundant than the syntopic congener H. cambodjense Benthem Jutting, 1962.

The specimens from locality no. 17 (Fig. 7F View Figure 7 ) could be identified to this species by having a smaller size than another congener, H. cambodjense . However, they differ slightly from the typical form in having less distinct peripheral ridges on the last whorl, while the protoconch, shell sculpture and major lamellae are identical to the topotype. Therefore, we consider these specimens to come within intraspecific variation.
