Material examined.

Lectotype of "var. viridis Möllendorff, 1898" SMF 7559 (Fig. 43F), lectotype of "var. varians Möllendorff, 1898" SMF 7561 (Fig. 44B), and holotype of "attapeuensis Thach & Huber, 2017" NHMUK 20170278 (Fig. 44C). Specimens from Xe Pian village, Paksong District, Champasak Province (Fig. 44A).

Distribution.

Laos, Thailand and probably in Vietnam ( Schileyko 2011, Inkhavilay et al. 2017, Thach 2017).

Remarks.

The holotype of Amphidromus attapeuensis Thach & Huber, 2017 has a greenish shell, purple lip and parietal callus, and brownish streaks on the apical whorls ( Thach 2017). These characters are identical to that of the banded colour form of A. haematostoma (see Inkhavilay et al. 2017). Therefore, we recognised this name as a junior synonym of A. haematostoma .
