Bulimus (Amphidromus) semitessellatus Morlet, 1885[1884]: 387, 388, pl. 11, fig. 2, 2a. Type locality: les montagnes qui bordent le grand fleuve au delà de Stung-Treng. Les forêts et les montagnes de Kampot à Compong-Som [Mountains and forest in Stung Treng, Kampot and Sihanoukville Provinces, Cambodia].

Material examined.
Locality no. 9: CUMZ-CM040 (2 shells). Locality no. 10: CUMZ-CM055 (1 shell). Locality no. 12: CUMZ-CM101 (2 shells; Fig. 11E View Figure 11 ). Locality no. 13: CUMZ-CM124 (2 shells). The empty shells were collected from the ground, and the living snails probably live on tree trunks and leaves.
Distribution.
Cambodia, Laos, Thailand and probably in Vietnam ( Schileyko 2011, Inkhavilay et al. 2017, 2019).
Remarks.
This species was described based on specimens collected from the area of Kampong Som [Sihanoukville] and Kampot ( Morlet 1885). Inkhavilay et al. (2017: fig. 10l) illustrated the lectotype of this species, which has a larger shell (height 35 mm) and the last whorl has only a blackish subsutural band (without any other bands on the last whorl) compared with the single worn shell that we collected from limestone near Kampot (height 23 mm), with brownish supra-peripheral and sub-peripheral bands. Thus, we provisionally identified these specimens as A. semitessellatus due to the similarity of both brown supra-peripheral and sub-peripheral bands on the penultimate whorls and the geographical proximity. The subgenus Syndromus typically has a small shell which exhibits high variation on shell size, colour, and pattern (see Inkhavilay et al. 2017).
