Stenotrema altispira (Pilsbry, 1894)

Family: Polygyridae
Common name: Highland Slitmouth

Width: 8.5-11 mm
Height: 6.5-8 mm
Whorls: 5+

The thin shell of Stenotrema altispira is beehive-shaped, with short, stiff hairs on the lower whorls. The shell is a bit taller than other slitmouth snails. The aperture is very narrow, with a long, slender parietal tooth. A slight indentation can be seen in the basal lip. The umbilicus is imperforate.

Synonyms for S. altispira include: Polygyra altispira, P. hirsuta altispira, and Stenotrema hirsutum.

It lives at higher elevations, in leaf litter and woody debris (Hubricht, 1985). In the Great Smoky Mountains S. altispira is found in various hardwood forest habitats (Dourson & Dourson, 2006).

Stenotrema altispira is only known from the mountains of Virginia, Tennessee and North Carolina. In Virginia it is reported only in Grayson and Smyth Counties.
