Euchemotrema

1

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 (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. 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.

Distribution

Euchemotrema is widely distributed in eastern and central North America.
