Paravitrea subtilis Hubricht, 1978
Common name: Slender Supercoil
Width: 2.5-3 mm
Height: 1.5 mm
The tightly coiled whorls of Paravitrea subtilis are marked with widely and irregularly-spaced radial growth lines. On the center whorls and the base of the shell, these lines are less distinct. The shell has a relatively tall aperture. Inside the final whorl, one or two sets of teeth are arranged in radial rows. Each row may contain between four and six teeth, and in some individuals, laminae replace the teeth.
Paravitrea subtilis may be found in leaf litter on hardwood slopes (Hubricht, 1985; Dourson, 2010).
There are no synonyms.
Paravitrea subtilis is scattered through a small number of counties in Virginia, Kentucky, and Tennessee (Hubricht, 1985). In Virginia it is known only from Wise County.
