Members of the 12 known species of the family Telothelepodidae, plus individuals of three additional undescribed species, were examined to infer phylogenetic relationships within the family and evaluate the status of genera. The outgroups include members of three species of Polycirridae and three of Thelepodidae. Members of 21 species, including both in- and outgroups, were coded for 47 subjects (‘characters’) and 109 characters sensu stricto (subject-predicate relations or ‘states’). The results, based on 15 minimum-length trees, each 103 steps long, suggest that telothelepodids should be divided into four genera, according to the morphology of the lower lip, presence or absence of eyespots, and visibility of segment 1. By necessity two of these genera are monotypic and plesiomorphic to two monophyletic genera; the latter two genera with five and eight species, respectively. Telothelepus, Parathelepus and Rhinothelepus are redefined, and the new genus Mesopothelepus gen. nov. is erected, all to accommodate the phylogenetic hypotheses presented. The problem of properly defining monotypic supraspecific taxon names as representative of phylogenetic hypotheses is discussed in relation to the inherent limitations of Article 13.1.1 of the International Code of Zoological Nomenclature.
