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.
描述并图示了1845年杜雅尔丹所命名的血管口线虫属（Angiostoma）的两个新物种，它们采自于在英国收集的陆生软体动物（腹足纲：柄眼目）的肠道。米氏血管口线虫（Angiostoma milacis）新种寄生于米氏蛞蝓和阿氏蛞蝓中，与1985年的阿萨马蒂血管口线虫（A. asamati Spiridonov）密切相关。带螺血管口线虫（Angiostoma zonitidis）新种发现于带螺中，与1992年（修订）的金默尔血管口线虫（A. kimmeriense Korol & Spiridonov）关系最为密切，该物种同样来自带螺。提出了一个修订后的属诊断。讨论了蛞蝓血管口线虫（A. limacis）和米氏血管口线虫新种在宿主中的分布情况，并给出了血管口线虫属物种的检索表。
