Family: Pristilomatidae
Common name: Barred Supercoil
Discovery: Hubricht, 1972
Identification
Width: 5-6 mm
Height: 2.5-3 mm
Whorls: 6+
The glossy, amber-colored shell of Paravitrea seradens may appear somewhat angular when juvenile, due to a flattened base and a square-shaped periphery. The periphery becomes more rounded with age. The final whorl expands abruptly and slopes downward as it approaches the aperture. A deep umbilicus provides a view of all the whorls. The outer and basal walls of the outer whorls have one or more pairs of large teeth, which are present at all stages of growth.
Ecology
This animal may be found in moist leaf litter on wooded slopes (Hubricht, 1985).
