Type locality.
Nui-Ba-Dinh, Phu-Ha, and Phu-Ly [Vietnam].
Material examined.
Type material. Only a single shell was available, viz. the syntype RBINS/MT/ 525051 ex. Dautzenberg collection (1 shell; Fig. 4H View Figure 4 , height 18.4 mm, width 26.3 mm).
Description.
Shell. Shell medium-sized, dextral, thin and depressed trochoid. Apex acute; embryonic shell smooth. Whorls 5-6, increasing regularly, slightly convex and slightly shouldered near suture; suture wide and shallow. Shell surface with fine growth lines. Last whorl large, angular with strong peripheral keel; slightly convex beneath. Shell monochrome, light brownish and translucent. Aperture semi-ovate; lip slightly expanded and brownish; parietal callus thin. Umbilicus closed; columella small and whitish.
Remark.
Globotrochus mellea is similar to Globotrochus onestera in almost all shell characters, except for its larger last whorl, strong angular peripheral keel and more depressed trochoid shell. Therefore, we provisionally retain Globotrochus mellea as a distinct species.
