Remarks.

The holotype of A. phuonglinhae Thach, 2017 is an immature specimen. The distinguished characters of yellowish-green periostracum and reddish-brown spiral band and columella (see Thach 2017) are identical to the typical colour form of A. roseolabiatus (see Inkhavilay et al. 2017). Therefore, we recognised this name as a junior synonym of A. roseolabiatus .
