Figs 21N, O View Figure 21 , 24B, C View Figure 24
Pupina pallens Möllendorff, 1894: 155, pl. 16, figs 27, 28. Type locality: Samui Islands, Gulf of Siam [Samui Island, Surat Thani Province, Thailand]. Fischer and Dautzenberg 1904: 431. BEDO 2017: 92. Sutcharit et al. 2018: fig. 5-13i.
Pupina (Tylotoechus) pallens - Kobelt 1902: 318, 319. Laidlaw 1928: 34. Zilch 1957: 47, pl. 2, fig. 16. Hemmen and Hemmen 2001: 39.
Type material examined.
Lectotype SMF 109951 (Figs 21N View Figure 21 , 24B View Figure 24 ) and paralectotypes SMF 109952 (4 shells), SMF 109953 (2 shells) from Golf von Siam: Koh Samui.
Other material examined.
CUMZ 12041 (1 shell) from Bang Phu Temple, Sam Roi Yot District, Prachuap Khiri Khan Province, 19 Oct. 2020. CUMZ 12042 (14 shells; Figs 21O View Figure 21 , 24C View Figure 24 ) from Suan Wiwek Bureau of Monks, Sam Roi Yot District, Prachuap Khiri Khan Province, 21 Oct. 2020.
Diagnosis.
Shell ovate; last whorl ca. three quarters of shell height. Apertural lip slightly thickened, not expanded; basal position widened. Both parietal and columellar teeth fin-shaped and slightly thickened; parietal tooth covering posterior canal; columellar tooth next to slit-like anterior canal.
Differential diagnosis.
Pupina pallens can be distinguished from all other species in the P. artata species group from mainland Southeast Asia by the widened basal position of the apertural lip.
Distribution.
The type locality ( Laidlaw 1928) and Prachuap Khiri Khan Province, western Thailand.
Remarks.
von Möllendorff (1894) stated that this species is different from P. arula in having "the more obtuse spire, the more distorted last whorl, and consequently the aperture placed more to the right and protracted at the base, the thinner outer peristome, the broader columella, the broad triangular parietal lamella, and the narrower lower incision". More sampling of this species, with both morphometric and molecular phylogenetic analyses, are needed to resolve the relationship between P. pallens and other species in the P. artata species group.
