Stenotrema edgarianum, also known as the Sequatchie slitmouth, is a rare, range-restricted species of pulmonate land snail in the family Polygyridae.

Physical appearance

[edit]

The Sequatchie slitmouth's shell is reddish-brown in color, irregularly striated, flat along the top, and convex below. The lip is thick with a narrow opening and a defined parietal tooth. The shell typically has 5 whorls.[1]

Ecology

[edit]

The Sequatchie slitmouth is endemic to the Appalachian Mountains, specifically the Cumberland Plateau, where it can be found in Marion, Sequatchie, Bledsoe, and Cumberland Counties in southeastern Tennessee.[2] Due to its rarity, the species is listed as imperiled globally and at the Tennessee state level.[3]

This species is found on logs or in leaf litter along wooded hillsides.[4] They are rarely found in large numbers.[5]
