Pseudopomatias amoenus Möllendorff, 1885

( Fig. 1A–D )

Pseudopomatias amoenus Möllendorff, 1885: p. 164 .

Pseudopomatias amoenus — Páll-Gergely et al., 2015: 30 , figs 5B–D, 6C, 12A–J.

Material examined. 1 corroded shell (H: 8.7 mm), JG/1, Laos, Bolikhamsay prov. , foot of isolated limestone hill adjacent to W slopes of Pha Gnotsan massif, Vangxouay Dam to Na Di road, ca 1 km before Na Di, 400 m a.s.l., 18°16.523′N, 104°42.821′E, coll. J. Grego, 18 February 2017 .

Remarks. A single, corroded shell of this species was collected in Bolikhamsay Province, which represents the first record of this widespread species in Laos. So far it was known in northern Vietnam, and the Chinese provinces of Yunnan, Sichuan, Chongqing, Hunan, Hubei, and Guangdong (Páll- Gergely et al., 2015). This is a very variable species ( Fig. 1A–D ), but can be recognised based on the aperture shape (straight parietal part, smoothly angled columellar-parietal transition and sharply angled parietal-palatal transition), the regular ribbing and the turriform shell shape.
