Locality no. 12: CUMZ-CM089 (4 shells). Locality no. 13: CUMZ-CM117 (2 shells; Fig. 10E ). The empty shells were collected among leaf litter in the limestone area. Remarks. Recently, Vermeulen et al. (2019b) introduced a species Macrochlamys psyche Vermeulen et al., 2019 based on the shell alone. However, its generic placement remains uncertain since genitalia data is still lacking. Godwin-Austen (1907) and Pholyotha et al. (2018) stated that most of the species attributed to " Macrochlamys " in Southeast Asia belong to the genus Sarika . This species is distinguished from the other known Sarika species in Cambodia by having a milky-coloured shell, flattened spire, and a relatively large shell (largest shell diameter 25 mm). These specimens differ from M. psyche in having a nearly flattened to slightly elevated spire, with a slightly shouldered last whorl and milky shell colour, while M. psyche has a slightly sunken spire, with a well-rounded last whorl and whitish shell colour (see Vermeulen et al. (2019b) for comparison).
