Bertia setzeri Thach, 2015 Fig. 3B

Bertia setzeri Thach, 2015: 240, 241, figs 1-4, 17-20. Type locality: Khanh Vinh District and Nha Trang outskirts, Khanh Hoa Province, central Vietnam. Thach 2016: 62, pl. 18, figs 267-269.

Remark.

Images of the holotype are shown in Figure 3B . Thach (2015) mentioned that this species differs from the B. cambojiensis in possessing a more depressed shell, slightly angular periphery and a monochrome dark colour below the periphery. The living specimen figured by Thach (2015: figs 17, 19) shows a similar aulacopod foot sole with less developed caudal horn than in the type species. An examination of the reproductive organs or molecular data are required to determine its systematic status.
