Two new species of Angiostoma Dujardin, 1845 taken from the intestines of terrestrial molluscs (Gastropoda: Stylommatophora) collected in the UK are described and illustrated. Angiostoma milacis n. sp. is parasitic in milacid and agriolimacid slugs and is closely related to A. asamati Spiridonov, 1985. Angiostoma zonitidis n. sp. was found in a zonitid snail and is most closely related to A. kimmeriense Korol & Spiridonov, 1992 (emend.), a species also from zonitid snails. An amended generic diagnosis is proposed. The distribution of A. limacis and A. milacis sp. n. in hosts is discussed and a key to the species of Angiostoma is presented.
