Xiphoarcturus – a new genus and two new species of the family Antarcturidae (Isopoda: Valvifera) from the Mar del Plata submarine canyon and its phylogenetic relationships
Xiphoarcturus kussakini gen.n., sp.n. and Xiphoarcturus carinatus gen.n., sp.n. are described from the Mar del Plata submarine canyon, South-West Atlantic Ocean. The new genus Xiphoarcturus has an elongate endopod of the uropod that extends to the end of the acuminate pleotelson; this elongate endop...
