Phylogenetic relationships within Tanaidacea were analyzed based on sequence data for the 18S
rRNA gene. Our results strongly supported a monophyletic group composed of Neotanaidae,
Tanaoidea, and Paratanaoidea, with the first two taxa forming a clade. These results contradict three
previously suggested hypotheses of relationships. Based on the molecular results, and considering
morphological similarities/differences between Neotanaidomorpha and Tanaidomorpha, we
demoted Suborder Neotanaidomorpha to Superfamily Neotanaoidea within Tanaidomorpha; with
this change, the classification of extant tanaidaceans becomes a two-suborder, four-superfamily
system. This revision required revision of the diagnoses for Tanaidomorpha and its three superfamilies.
The results for Apseudomorpha were ambiguous: this taxon was monophyletic in the maximum
likelihood and Bayesian analyses, but paraphyletic in the maximum parsimony and minimum
evolution analyses.
