Genus Pseudopomatias Möllendorff, 1885

Pseudopomatias Möllendorff, 1885 : p. 164. Fargesia Heude, 1886 : p. 211.

Fargesia — Johnson 1973: p. 34.

Type species. Pseudopomatias amoenus Möllendorff, 1885 by monotypy.

Diagnosis. Shell small to large, turriform or spindle-shaped, rather regularly ribbed; aperture rather round with slight columellar-parietal and parietal-palatal transitions; the latter is usually more angled; the parietal side is usually straight; peristome consists of two circles, in some species it appears as "single"; basal keel missing; operculum densely coiled, thin, membranous ( Figs 5 C–F).

Differential diagnosis. Differs from Eucataulus Kobelt, 1902 (often referred as subgenus of Tortulosa Gray, 1847 ), Nodopomatias , Tortulosa (syn: Perlisia Tomlin, 1948 ) and Vargapupa n. gen. by the absence of a basal keel. Moreover, Tortulosa and Eucataulus usually have smooth shells and a basal canal in the aperture. Schistoloma Kobelt, 1902 (synonym: Pinteria Varga, 1972 , see Egorov 2013) also has a more corpulent, smooth shell and some species possesses a basal keel. Pseudopomatias lacks the additional line (groove) above the suture, which is present in Csomapupa n. gen. The Australian genus Hedleya Cox, 1892 also has a similar shell in terms of shape and ribbing, but it has two canals in the aperture.
