Euchemotrema is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
The shell of species in this genus is usually about 8 to 11 mm in diameter (about 3/8 inch). The shells are brown with a velvety surface, similar to that of Stenotrema, and, in fact, this genus is sometimes combined into Stenotrema.[2] These snails typically have a less complex aperture than Stenotrema: "without a tooth within the outer arc of the lip and with no notch in the basal lip".[2]
There are also peculiarities of the male anatomy that separate the two genera.
