Material examined.

Holotype of "fuscolabris Möllendorff, 1898" SMF 7641 figured in Inkhavilay et al. (2017: fig. 13i) and holotype of "thakhekensis Thach & Huber, 2017" MNHN-IM-2000-33216 (Fig. 42F). Specimens CUMZ 7040, 7042 from Ban Phone village, Lamam District, Sekong Province (Figs 43A, B, 57G, H).

Distribution.

Known from several localities in Laos and probably in Vietnam ( Schileyko 2011, Inkhavilay et al. 2017, Thach 2017).

Remarks.

The holotype of Amphidromus thakhekensis Thach & Huber, 2017 is identical to the un-banded colour form of A. fuscolabris , which probably reflects intra-population variation rather than separate biological species entities. Therefore, we recognised this name as a junior synonym of A. fuscolabris .
