摘要: Temnocephalida includes species demonstrating many intermediate steps presenting the transition from commensalism to parasitism. Dramatic morphological changes also occurred within this group but number of supraspecific taxa is small, making an excellent model for evolutionary studies. Having summarised original and relevant published data, we suggest a cladogram (phylogenetic tree) which nearly fully resolves order branching families main genera Temnocephalida. We introduce new family, Diceratocephalidae nov. fam.
