Stenotrema maxillatum, also known as the ridge-lip slitmouth, is a species of pulmonate land snail in the family Polygridae.
Physical appearance
Ridge-lip slitmouths possess small, globose shells, typically chestnut brown in color. The aperture is long, pale, and narrow, with a defined, protruding outer lip. The parietal tooth is hidden behind the outer lip. The ridge-lip slitmouth is most visually similar to Stenotrema hirsutum, except it is smaller and the shell is more globose.[1]
Ecology
The ridge-lip slitmouth is endemic to the southeastern United States, where it has been found in Alabama and Georgia. The species is listed as vulnerable.[2]
This species is most commonly found in leaf litter or on rocks and logs along wooded hillsides and ravines.[3]
