Locality no. 9: CUMZ-CM032 (12 shells), CUMZ-CM033 (3 shells). Locality no. 10: CUMZ-CM050 (24 shells), CUMZ-CM051 (1 shell; Fig. 10D ). The empty shells were collected among leaf litter in the limestone area. Remarks. The common ground dwelling snail genus Sarika is probably restricted to the Indochina region ( Godwin-Austen 1907 ). Identifications at species level in Sarika based solely on shells cannot be achieved with confidence because of the limited distinguishing shell characters. Species level distinguishing characters in Sarika are based mainly on their reproductive anatomy. However, this specimen can be discriminated from S. bocourti (Morelet, 1875) by having a reddish-brown shell with a wide whitish or creamy area surrounding the umbilicus. Sarika bocourti , which is described from "Battambang, Cambodje", has a uniform brownish shell (see Breure et al. (2018 : fig. 135) for the syntype).
