Ancotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Haplotrematidae.

This genus is sometimes considered to be a subgenus of Haplotrema . Haplotrema and Ancotrema cannot be distinguished only on the basis of their shells, but can be distinguished on the basis of their detailed internal anatomy. [3]

The genus Ancotrema contains the following species: [4] [5]
