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.[2]
The genus Ancotrema contains the following species:[3][4]
- Ancotrema hybridum (Ancey, 1888); Oregon lancetooth
- Ancotrema sportella (Gould, 1846); beaded lancetooth
- Ancotrema voyanum (Newcomb, 1865); hooded lancetooth
- Ancotrema zopherum Roth, 1990: dusky lancetooth
