Description
Pupoid shell, to 45 mm length and 20 mm diameter, color varying from tan to orange, reddish-brown, and dark brown, possibly dark purple. Old specimens are often finely pitted. Whorls 5-7, transverse growth lines present, sutures linear and slightly impressed, apex obtuse and occasionally distorted to the left (assuming standard anatomical position), spire short. Penultimate body whorl may appear inflated relative to whorls on either side. Aperture circular with a right posterior triangular breathing structure. Peristome thickened, white to shell colored, with a thin parietal declining shoulder inside; umbilicus narrow. Operculum concentric, thick, and calcareous.
Radula with teeth in a 2-1-1-1-2 arrangement, based on the figure in Kongim et al. (2013[4]: Figure 6E). Central tooth with three cusps, the middle one longer that the others. Lateral teeth with one large cusp and one smaller cusp on the central side. Marginals with one large central cusp flanked by one smaller cusp on each time. Kongim et al. (2013)[4] described the radula as having more cusps per tooth than illustrated.
Distribution
Northern Vietnam south to Đà Nẵng (Figure 5). Possibly in Guangxi autonomous region and Yunnan Province, China.
Discussion
By synonymizing Pollicaria rochebruni and Pollicaria crossei, we suggest that all Pollicaria specimens from Vietnam that possess an interiorly shouldered peristome are a single species, excluding some smaller (< 35 mm) individuals with bright orange shells. We found live specimens of Pollicaria rochebruni at the bases of and in the valleys between karst outcrops in northern Vietnam. Reports from local farmers indicated that snails are more abundant during the spring rains, when native residents eat them as a delicacy. Some Chinese shells found for sale on the Internet are consistent morphologically with Pollicaria rochebruni but may represent a separate species.
