Shell description
editThese are among the smallest snails in the Polygyridae, with shell diameters of about 4 to 6 mm (approximately 1/5 inch). The shells of this species usually have a velvety surface, as a consequence of numerous hair-like extensions of the surface covering of the shell, the periostracum.
Distribution
editThe known distribution of this species is limited to the United States: along the Gulf of Mexico from Texas to Florida, as well as Georgia, and the Mississippi valley from Arkansas to Indiana.[1]

editThis genus includes the following species and subspecies:[1][2][3][4]
- Lobosculum leporinum (Gould, 1848)
- Lobosculum pustula (Férussac, 1822)
- Lobosculum pustuloides (Bland, 1858)
