Stenotrema macgregori Dourson, 2011 (not yet reported)
Common name: Fraudulent Slitmouth
Width: 8-10 mm
The shell of this snail is pill-shaped and imperforate. The parietal tooth is long, the basal notch shallow, and the interdenticular notch almost non-existent. Within the shell aperture is a short fulcrum. Short stiff “hairs” upon the periostracum sparsely cover the outer surface. The shell is smaller than S. stenotrema and has a slightly wider aperture (Dourson, 2011).
In eastern Kentucky, Stenotrema macgregori lives in leaf litter in richer, mid-elevation forests of Pine Mountain on the Virginia border (Dourson, 2011). It is absent from more acid hemlock stands, rhododendron patches, and ridgetops.
There are no synonyms for this recently-described species.
Although this species has not yet been reported in Virginia, it may well be found in the western counties abutting Kentucky.
