The molecular phylogeny and morphology of the oxyuroid nematode genus Aspiculuris from voles and house mice has been examined. Wonns collected from Myodes glareolus in Poland, Eire and the UK are identified as Aspiculuris tianjinensis, previously known only from China, while wonns from Mus musculus from a range of locations in Europe and from laboratory mice, all conformed to the description of Arpiluluris turaptera. Worms from voles and house mice are not cloaely related and are not derived from each other, with A. tianjinensis, being being most closely related to Aspiculuris dinniki from snow voles and to an isolate from Microtus longicaudus in the Nearctic. Both A. tianjinensis and A. tetraptera appear to represent recent radiations within their host groups; in voles, this radiation cannot be more than 2 million years old, while in commensal house mice it is likely to be less than 10 000 years old. The potential of Aspiculuris spp.as markers of host evolution is highlighted.
