Material examined.

Holotype of "richgoldbergi Thach & Huber, 2017" FMNH 381986 (Fig. 43E). Specimens CUMZ 7015 (Fig. 43D) from Tad Lor waterfall, Salavan District, Salavan Province.

Distribution.

Laos and Thailand ( Sutcharit and Panha 2006, Inkhavilay et al. 2017).

Remarks.

Amphidromus richgoldbergi Thach & Huber, 2017 has a dextral shell, yellowish-green periostracum and a brownish spot on the apex ( Thach 2017). These characters are the intraspecific variations of A. givenchyi ( Sutcharit and Panha 2006, Inkhavilay et al. 2017) rather than indicative of different biological species entities. Therefore, we recognised this name as a junior synonym of A. givenchyi .
