The life cycle of Brachylaima ruminae n.sp. (Trematoda: Brachylaimidae), a duodenal parasite of rodents on the Mediterranean island of Formentera (Spain) is elucidated. The new species follows a terrestrial triheteroxenous life cycle. Eggs passed in the faeces of the definitive host must be ingested by a specific first intermediate host, the land snail Rumina decollata. Branched cercariogenous sporocysts develop in the digestive gland. Microcercous cercariae come out through the terminal birth pores of the branches. Cercariae shed by the snail are terrestrial, crawling on humid substratum. They contact the second intermediate host, another land snail, principally the species R. decollata and less frequently slugs and Helicids. Cercariae enter via the excretory pore and kidney duct to their specific final location, the kidney. Unencysted metacercariae develop in the kidney (also, less frequently, in the pedal glands) to the mature, infective stage. Infective metacercariae infest the definitive host when ingested together with the snail.
阐明了短颈阔盘吸虫新种（吸虫纲：短颈阔盘科）的生活史，该吸虫是西班牙地中海岛屿福门特拉岛啮齿动物十二指肠内的寄生虫。新物种遵循陆地三宿主异寄主生活史。终末宿主粪便中排出的虫卵必须被特定的第一中间宿主，即陆地蜗牛皱疤坚螺吞食。在消化腺中发育出分支状的产尾蚴子胞蚴。微尾尾蚴通过分支末端的生殖孔逸出。蜗牛排出的尾蚴生活在陆地上，在潮湿的基质上爬行。它们接触第二中间宿主，即另一种陆地蜗牛，主要是皱疤坚螺，较少情况下是蛞蝓和柄眼目蜗牛。尾蚴通过排泄孔和肾管进入其特定的最终位置，即肾脏。未包囊的后尾蚴在肾脏（较少情况下也在足腺）发育至成熟的感染阶段。感染性后尾蚴与蜗牛一同被吞食时感染终末宿主。
