Thapsia is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the subfamily Sheldoniinae of the family Urocyclidae.[2]
Description
Species attributed to the genus Thapsia sensu lato have shell diameters ranging from about 15 to 30 mm, with 5½-6½ whorls. These rather featureless dextral shells are characterized by a low spire and their yellow to brown color. The spiral sculpture of the postembryonic shell is slender. In some larger * The sculpture of the radial ribs is formed crosswise (like the letter X) or beadlike. The foot shows a long caudal horn.
Species
Thapsia was originally designated in 1860 by German zoologist Johann Christian Albers as a subgenus of Nanina Gray, 1834, non Risso, 1826.[1]
This genus is a heterogeneous assemblage. Because the shell characters of this genus converge with those of the larger specimens of some closely related genera (Saphtia Winter, 2008,[3] Pseudosaphtia Winter, 2008[3] and Vanmolia Winter, 2008[3]), the delimitation of * To Thapsia s.l. is difficult. There very few papers that describe the anatomical features of this genus.
