Abstract

The genus Bunodera (Trematoda: Allocreadiidae) is represented by 5 freshwater species that include the widely distributed, holarctic, B. luciopercae in mainly perch and related percids, the endemic North American species B. sacculata in percids, B. eucaliae and B. inconstans in freshwater sticklebacks, and the trans-Pacific B. mediovitellata in sticklebacks. Their varied biogeography and host-associations provide a potential model system to investigate endemicity, speciation modes and coevolutionary phenomena. Partial sequences of selected regions of the 28s ribosomal RNA gene in combination with morphological data were used to build a hypothesis of relationships of Bunodera spp., which in turn is used as a basis for discussing the co-evolutionary and speciation history in this parasite group. Results from the combined data yielded a tree (C.I. = 0.82) identical in topology to that obtained from the molecular data alone, which supported the following resolution: ((((B. luciopercae (((B. sacculata ((B. mediovitellata (B. eucaliae + B. inconstans)))). The basal position of B. luciopercae is consistent with its holarctic distribution and a basal percid as its main host. The more basal positions of two typical perch parasites and the association of a more derived clade (B. mediovitellata + B. eucaliae + B. inconstans) with sticklebacks indicates host-shifting from percids to sticklebacks. In addition, the sister relationships and North American endemicity of the two most derived species, B. euclaiae and B. inconstans is also consistent with the more derived position of their host, the freshwater brook stickleback, and with the speciation and diversification of gasterosteids in Nearctic freshwaters.
