"Xolotrema" is a genus (or subgenus under "Triodopsis") of terrestrial snails in the family Polygyridae. Pilsbry (1940) [Pilsbry, Henry A. (1940). Land Mollusca of North America (North of Mexico). Acad. Nat. Sci. Philadelphia, Monograph 3, vol. 1(2): 823.] characterizes "Xolotrema" (which he considered to be a subgenus): "Triodopses in which the inner margin of the basal lip has a long bladelike lamella, terminating at a notch where it joins the outher arc of the lip; the embryonic whorls are covered with close retractive radial striae (subobsolete in "T. fosteri")."

The genus "Xolotrema" contains the following species:
* "Xolotrema notata"
* "Xolotrema obstricta"
* "Xolotrema carolinensis"
* "Xolotrema fosteri"
