Locality no. 12: CUMZ-CM115 (1 shell). Locality no. 3: CUMZ-CM123 (1 specimen in ethanol). Locality no. 17: CUMZ-CM136 (4 shells). Locality no. 18: CUMZ-CM145 (1 shell). Locality no. 14: CUMZ-CM149 (1 shell). Locality no. 16: CUMZ-CM171 (1 shell; Fig. 10C ), CUMZ-CM172 (1 specimen in ethanol). Locality no. 6: CUMZ-CM180 (3 specimens in ethanol). The small juveniles were found on tree trunks and leaves, while the adults were found to live on the ground among leaf litter.

Distribution.

Cambodia, Laos, Thailand and Vietnam ( Schileyko 2011, Inkhavilay et al. 2019).

Remarks.

This is one of the largest land snail species recorded from Indochina. Hemiplecta distincta has a wide distribution from Southern Vietnam, throughout Cambodia, northeastern Thailand, and throughout Laos ( Schileyko 2011, Inkhavilay et al. 2019). The snails are widely used as local food and are gathered for personal consumption or sold in high quantities, especially in Northeastern Thailand and Laos ( Panha 1987). This species is an intermediate host of the rat lungworm Angiostrongylus cantonensis in Cambodia ( Brumpt et al. 1968).
