Paravitrea placentula (Shuttleworth, 1852)
Common name: Glossy Supercoil
Width: 6-7.5 mm
Height: 3-4 mm
The closely coiled shell of Paravitrea placentula is glossy-transparent and sculptured with irregularly-spaced radial striae. The base is convex and the umbilicus is open. The lunar-shaped aperture has a simple lip. Though similar in shape to P. capsella, this shell is larger and has a smaller umbilicus.
Paravitrea placentula can be found under leaf litter on wooded slopes (Hubricht, 1985).
Synonyms for P. placentula include Helix (Hyalina) monroensis, Paravitrea lithodora, P. placentula lithodora, Vitrea placentula, and Zonites placentula.
This is an Appalachian Mountain species, ranging from Virginia and Kentucky in the north to Georgia in the south. In Virginia it is reported only from Dickinson County.
