Stenotrema angellum, also known as the Kentucky slitmouth, is a species of pulmonate land snail in the family Polygridae.
The Kentucky slitmouth possesses an irregularly striate, lens-shaped, conoid shell with 5 to 5.5 whorls and a convex base. The shell's periphery is bluntly angular along the front, but gradually becomes more rounded behind the lip. The shell can range from cameo brown to snuff brown in color, and the surface is covered in short, coarse hairs typical of species in the Stenotrema genus. The aperture is narrow with a long, brownish parietal tooth. [1]
Mature Kentucky slitmouths tend to average around 6.23 mm (0.25 in) in height and 10.68 mm (0.42 in) in diameter. [1]
Malacologist Leslie Hubricht originally described the species in Indiana, Kentucky, and Tennessee. [1] The species is listed as secure in Kentucky and vulnerable in Tennessee. [2]
Kentucky slitmouth populations are concentrated across Kentucky, with populations along the southern border of Indiana and north-central border of Tennessee being at the very edges of the species' range. [2] The snail is only found in Jefferson, Clark, Harrison, and Crawford Counties in Indiana, and Clay, Fentress, Pickett, Jackson Counties in Tennessee. [2] [1] The populations found in Fentress and Pickett Counties were located in Skillmans Mark Cave and Bunkham Cave respectively. [3]
This species is most commonly found in mixed hardwood forests along wooded hillsides or ravines. They can be found crawling in thick, wet to damp leaf litter or under rotting logs. [4] They may also be found around limestone escarpments. [5]
Pickett County is a county located in the U.S. state of Tennessee. As of the 2020 census, the population was 5,001, making it the least populous county in Tennessee. Its county seat is Byrdstown. The city of Byrdstown and the Kentucky town of Albany, 11 miles (18 km) to the northeast, are positioned between two Army Corps of Engineers lakes: Dale Hollow Lake, mainly in Tennessee, and Lake Cumberland, in Kentucky. The area is known as "Twin Lakes" and Byrdstown is noted as "The Gateway To Dale Hollow Lake". Every year thousands of people vacation at the many resorts situated along the lakes.
Fentress County is a county located in the U.S. state of Tennessee. As of the 2020 census, the population was 18,489. Its county seat is Jamestown.
Wayne County is a county in the U.S. state of Kentucky along the southern border with Tennessee. As of the 2020 census, the population was 19,555. Its county seat is Monticello. The county, on the south-central border with Tennessee, was named for Gen. Anthony Wayne, a Revolutionary War hero. As of November 3, 2020, Wayne County is a wet county—a measure allowing the sales and consumption of alcoholic drinks passed by a margin of 4,901 for and 3,966 against.

Anguispira picta, common names painted snake-coiled forest snail and painted tigersnail, is a rare species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Discidae, the disc snails. It is a limestone specialist, and is limited to outcrops with suitable mineralogy.
The Tumbling Creek cavesnail is a species of freshwater cave snail with gills and an operculum, an aquatic gastropod mollusk in the family Amnicolidae.
Stenotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae. Members of this genus are known as slitmouths. These are typically small to medium-sized snails, with a velvety or hairy shell surface, and a narrow aperture which is usually closely guarded by well-developed "teeth".
Rich Mountain slitmouth or Pilsbry's narrow-apertured land snail, scientific name Stenotrema pilsbryi, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Polygyridae. This species is endemic to Ouachita Mountains of the United States.
Anguispira alternata, also known as the flamed disc or flamed tigersnail, is a species of pulmonate land snail in the family Discidae, the disk snails. It is the most common and widespread member of the Anguispira genus, and one of the more common land snail species in North America.
Anguispira cumberlandiana, also known as the Cumberland tigersnail or the Cumberland disc, is a range-restricted species of pulmonate land snail in the family Discidae, the disk snails. The species is named after the Cumberland Plateau, a section of the Appalachian Plateau that overlaps with its range.
Leslie Hubricht was an American biologist and malacologist.
Anguispira alabama, also known as the Alabama tigersnail or Alabama disc, is a rare, range-restricted species of pulmonate land snail found in Alabama and Tennessee. Due to its rarity and the difficulty of locating new populations, the species is listed as vulnerable in both states.
Anguispira jessica, also known as the mountain tigersnail or mountain disc, is a species of pulmonate land snail– a gastropod mollusk in the family Discidae, the disk snails. The species is named after G.M. Kutchka's wife Jessica; he was the first to describe the species in 1938. It was originally considered a subspecies of Angusipira alternata, but has since been elevated to species status.
Anguispira fergusoni, also known as the coastal plain tigersnail or coastal plain disk, is a species of pulmonate land snail in the family Discidae, the disk snails. It is found in multiple states along the east coast of the United States.
Anguispira knoxensis, also known as the rustic tigersnail or rustic disk, is a rare species of pulmonate land snail in the family Discidae, the disk snails. It is endemic to the Great Smoky Mountains in southeastern Tennessee. It was originally considered a subspecies of Anguispira alternata.
Anguispira mordax, also known as the Appalachian tigersnail, is a species of pulmonate land snail in the family Discidae endemic to the southeastern United States. It is named after the Appalachian mountain range.
Anguispira rugoderma, also known as the Pine Mountain tigersnail, is a rare, narrow-ranged species of pulmonate land snail in the family Discidae, the disk snails. It is named after the Pine Mounatin ridge, a section of the Appalachian Mountains that overlaps with the snail's range.
