The maintenance of strict host specificity by parasites when several closely related host species live in sympatry is poorly understood. Species of intertidal trochid snails in the genera Diloma, Melagraphia and Austrocochlea often occur together and are parasitised by a single digenean morphotype (Platyhelminthes, Trematoda), tentatively placed in Opecoelidae. Of the 10 trochid species (6 from New Zealand, 4 from Australia) we examined, six were found to be infected, and the prevalence of… CONTINUE READING
