On the phylogenetic relationships of Axiokebuita, Travisia and Scalibregmatidae (Polychaeta)
We provide a description of newly collected specimens of Axiokebuita Pocklington & Fournier from Norway, previously known only from east Canada and the Antarctic. Due to delineation problems between the only two described species, A. minuta (Hartman) and A. millsi Pocklington & Fournier, the...
