| Sumario: | A new genus is established to accommodate a new species of freshwater centropagid related to the Boeckella clade. Karukinka fueguina n. gen., n. sp., is described on two males from a sample collected from an ephemeral pond in Tierra del Fuego. Diagnostic features of the new taxon are almost exclusively related to the male fifth legs, since females are unknown. The number of characters of these appendages in a plesiomorphic state, the most striking feature of which is the presence of swimming setae on both exopods, makes it unique among the Centropagidae. Otherwise, the characters indicate its close relationship to the ancestor of Boeckella and thus make it the best available living species to be used as an outgroup in phylogenetic studies of the species of this genus. |
