Trochomorpha sp. Fig. 10B

Material examined.

Locality no. 10: CUMZ-CM057 (2 shells; Fig. 10B), CUMZ-CM058 (1 shell), CUMZ-CM059 (1 specimen in ethanol). Locality no. 13: CUMZ-CM134 (3 shells). The snail was found to live on a tree trunk.

Remarks.

The specimens from Prasat Phnom Totong (locality no. 10) have a conic shell with a very strong and sharp peripheral keel, widely opened and deep umbilicus, and slightly convex below the periphery. The shell surface has irregular growth lines and very thin spiral ridges. These specimens tend to differ from T. paviei and T. saigonensis in having a larger shell (shell width 14 mm), an elevated domed spire, more whorls, and being nearly flat below the periphery. However, the identification is provisional, and further evidence from examination of genitalia or DNA will be necessary to elucidate their status.
