Type material.
Holotype CUMZ 12147/1 (Figs 36G View Figure 36 , 40C View Figure 40 ), 10 Sept. 2016, coll. R. Srisonchai, A. Pholyotha, T. Seesamut. Measurement: shell height 9.4 mm, shell width 6.3 mm and 6½ whorls. Paratypes CUMZ 12147/2 (1 specimen in ethanol) and NHMUK 20210336 (1 shell; Figs 36H View Figure 36 , 40D View Figure 40 ), same data as holotype.
Type locality.
Wat Ratburana School, Lang Suan District, Chumpon Province, Thailand, 9°56'18.0"N, 99°02'25.5"E, 20 m amsl.
Diagnosis.
Shell ovate-fusiform; last whorl ca. 70% of shell height. Apertural lip highly thickened and slightly expanded; with a furrow between inner and outer peristomes; inner peristome thickened, cord-like. Both parietal and columellar teeth fin-shaped, very thickened, always located next to and not covering its respective canal. Posterior canal slightly bulging outward.
Differential diagnosis.
P. stoliczkai sp. nov. is most similar to P. aureola in shell shape in having both fin-shaped and highly thickened parietal and columellar teeth located next to their respective canals, and the posterior canal slightly bulging outward. However, P. stoliczkai sp. nov. has a furrow between inner and outer peristomes, with inner peristome thickened and cord-like.
Description.
Shell height 6.3-6.4 mm; shell width 9.0-9.5 mm. Shell ovate-fusiform, solid, semi-transparent, reddish brown, devoid of prominent sculpture on glazed smooth surface. Apex obtuse. Growth lines on shell surface inconspicuous. Whorls 6- 6½, last whorl large (ca. 70% of shell height). Spire angle ca. 80-90°; slightly extended. Sutures slightly impressed, but shallow. Aperture circular; lip highly thickened (ca. 0.4-0.5 mm wide and 0.6-0.7 mm thick) with paler colour, slightly expanded. Aperture with a furrow between inner and outer peristomes, with inner peristome thickened, cord-like. Parietal callus sharply defined and thickened with paler colour. Peristome interrupted by two canals; posterior canal ca. 1.4 mm long and 0.7 mm at its widest, slightly bulging outward, continuing obliquely and widening vertically upward when observed from lateral view. Anterior canal curved and continuing obliquely upward ca. 2.0 mm. Parietal tooth fin-shaped, highly thickened (ca. 1.5 mm long, 0.5 mm at its widest and 0.3 mm thick), always located next to and not covering posterior canal. Columellar tooth fin-shaped, highly thickened (ca. 1.9 mm long, 0.5 mm at its widest and 0.3 mm thick), located next to anterior canal. Umbilicus closed. Operculum round, thick, flat, multispiral, whitish to pale yellow, opaque corneous with smooth edge.
Etymology.
The specific epithet is dedicated to F. Stoliczka, a Czech palaeontologist and zoologist, who described P. aureola , to which this new species is associated with.
