"Ancotrema" is a genus of land snail in the family Haplotrematidae, although it is sometimes considered to be a subgenus of "Haplotrema". "Haplotrema" and "Ancotrema" can not be distinguished on the basis of their shells, but rather only in terms of their detailed internal anatomy. [Pilsbry, Henry A. (1946). Land Mollusca of North America (North of Mexico). Acad. Nat. Sci. Philadelphia, Monograph 3, vol. 2(1): 225-230.]
