Isozyme electrophoresis was used to assess possible cospeciation of
parasites (cestodes of the Progamotaenia festiva complex) and their hosts
(Australian diprotodont marsupials) and to compare the extent of
interspecific genetic diversity of the parasites and their hosts. On the
basis of morphology, there are three species in the complex, although
electrophoresis revealed 14 distinct genetic types, most of which were host
specific, although there were three cases of apparent host switching. The
evolutionary relationships among the parasites were only partially
concordant with those among the hosts. Moreover, the extent of
electrophoretic diversity among the parasites was much higher than that
among hosts.
