Two new species of Portanus Ball, 1932 are described and illustrated from Brazil. P. hastatus sp. nov. from Ceará State, can be recognized by its acute pygofer apex and aedeagus with pair of apical processes directed dorsally. Portanus phoenicius sp. nov. from Piauí State, can be recognized by its rounded pygofer lobe with dorsal tooth turned inwardly, aedeagus apex with pair of elongate processes and pair of rounded flanges directed ventrally. Portanus boliviensis is newly recorded from Brazil. These findings double the number of species of Portanini recorded from Northeastern Brazil.
