Euchemotrema
Euchemotrema is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Shell description
The shell of species in this genus is usually about 8 to 11 mm in diameter. The shells are brown with a velvety surface, similar to that of Stenotrema, and, in fact, this genus is sometimes combined into Stenotrema. 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".There are also peculiarities of the male anatomy that separate the two genera.
