Climate and host demographic cycling often shape both parasite genetic diversity and host distributions, processes that transcend a history of strict host–parasite association. We explored host associations and histories based on an evaluation of mitochondrial and nuclear sequences to reveal the underlying history and genetic structure of a pinworm,Rauschtineria eutamii, infecting ten species of western North American chipmunks (Rodentia:Tamias, subgenusNeotamias).Rauschtineria eutamiicontains divergent lineages influenced by the diversity of hosts and variation across the complex topography of western North America. We recovered six reciprocally monophyleticR. eutamiimitochondrial clades, largely supported by a multilocus concordance tree, exhibiting divergence levels comparable with intraspecific variation reported for other nematodes. Phylogenetic relationships among pinworm clades suggest thatR. eutamiicolonized an ancestral lineage of western chipmunks and lineages persisted during historical isolation in divergingNeotamiasspecies or species groups. Pinworm diversification, however, is incongruent and asynchronous relative to host diversification. Secondarily, patterns of shallow divergence were shaped by geography through events of episodic colonization reflecting an interaction of taxon pulses and ecological fitting among assemblages in recurrent sympatry. Pinworms occasionally infect geographically proximal host species; however, host switching may be unstable or ephemeral, as there is no signal of host switching in the deeper history ofR. eutamii.
