Abstract

Two new species of the genus Pseudomesus Hansen, 1916 (Isopoda, Asellota) are described from the Southern hemisphere: Pseudomesus pitombo sp. nov. and Pseudomesus satanus sp. nov. Specimens of the new species were collected during DIVA-1 (DIVersity of the abyssal Atlantic Ocean) in the deep Angola Basin (P. pitombo) and a cruise to the Australian continental slope (P. satanus), respectively. They differ from the remaining species of this genus by the presence of a mandibular palp. P. pitombo can be distinguished from P. satanus by the shape of the anterior margin of the cephalothorax of the female, in the number of articles of the antenna, and the length of the maxilliped´s exopodite.
