"Stenotrema" is a genus of gastropod in the family Polygyridae. These are typically small to medium snails, with a velvety or hairy surface and a narrow aperture, usually closely guarded by well-developed "teeth". The genus occurs throughout most of North America, from Alaska, though Canada and the United States, into Mexico. Pilsbry, Henry A. 1940. "Land Mollusca of North America (North of Mexico)". Acad.
