Abstract
The phylogeny of European species of the tapeworm genus Proteocephalus was studied, based on partial 18S rDNA and morphological data. The group was found to be monophyletic. The analysis showed a low informative value of available morphological characters in comparison with molecular data. The morphological matrix resulted in a poorly resolved tree which is, however, compatible with the topology ( Proteocephalus osculatus ( Proteocephalus torulosus ( Proteocephalus macrocephalus, Proteocephalus filicollis) ( Proteocephalus tetrastomus, Proteocephalus percae, Proteocephalus longicollis))) based on the 18S rDNA data. A comparison performed by the program TreeMap showed a lack of significant congruency between parasite and host phylogenies. Therefore, the distribution of species in their hosts appears to be independent of the phylogeny and it is likely to be a result of host-switching, rather than co-speciation events.
