Stenotrema altispira, also known as the highland slitmouth, is a species of pulmonate land snail in the family Polygridae.

[1] The highland slitmouth possesses a brown, domed shell that is slightly taller than other species in the Stenotrema genus.

The shell's surface is covered with short, stiff hairs.

The aperture is paler than the rest of the shell, with a narrow opening and a long parietal tooth.

[1] The species can only be found in Grayson and Smyth Counties in Virginia, and is therefore at risk of extirpation.
