Xolotrema is a genus (or subgenus under Triodopsis) of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.
Shell description[edit]
Pilsbry (1940)[3] characterized the shell of Xolotrema (which he considered to be a subgenus) thus:
"Triodopses, in which the inner margin of the basal lip has a long bladelike lamella, terminating at a notch where it joins the outer arc of the lip; the embryonic whorls are covered with close retractive radial striae (subobsolete in T. fosteri)."
Species[edit]
