Description.
Shell: This nominotypical subspecies is characterized by the large shell size ( Table 2 View Table 2 ). Shell with last whorl and penultimate whorl purple to black; first to third whorls distinct yellow to bright orange. Lip expanded, red to orange.
Radula: Taenioglossate radula, teeth arrangement with central, lateral and marginal teeth shape similar to Pollicaria myersii . Differences include a central tooth with well developed central cusp and lateral cusp on each side; lateral teeth triangular in shape with a pointed tip; inner marginal teeth composed of 3 cusps; central cusp flanked with small inner and outer lateral cusps.
Distribution.
This subspecies occupies the southern limit of the species’ range in Cambodia and several localities in Loei, Phitsanulok, Chaiyaphum, Khon Kaen, Phetchabun Nakhon Ratchasima and Saraburi Provinces in Thailand.
Remarks.
The characters distinguishing this nominotypical subspecies from Pollicaria myersii are the smaller shell size and mainly purple coloured shell with whorls 2-3 pale to bright orange and bright orange to red lip ( Tables 1 View Table 1 , 2 View Table 2 ), and a distinct karyotype pattern ( Kongim et al. 2009, 2010).
