Abstract: | Phylogenetic relations among tanaidacean genera within ‘Akanthophoreinae’ are addressed using computer-assisted parsimony methods. The morphology-based analysis includes 10 well-defined and described genera: Araphura, Chauliopleona, Collettea, Paragathotanais, Metagathotanais, Paraleptognathia, Paranarthrura, Portaratrum, and Tanaella in Tanaidomorpha, and Glabroapseudes in Apseudomorpha as the outgroup. Chauliopleona and Paraleptognathia form a monophylum; Portaratrum cannot be placed in any known family. These three genera are considered as incertae sedis. The analysis does not support the monophyly of ‘Akanthophoreinae’, and further questions the monophyly of Tanaellidae. |
