Substitution saturation and nuclear paralogs of commonly employed phylogenetic markers in the Caryophyllidea, an unusual group of non-segmented tapeworms (Platyhelminthes)

► Interrelationships of a unique group of tapeworms tested using mt and rDNA markers. ► Lineage-specific nuclear paralogs of mtDNA (“numts”) found in 52% of the taxa. ► Both mt coding and nuclear ribosomal genes show high levels of saturation. ► Split-decomposition analyses reveal a lack of distinct historical signal in the data.
