Two new maldanid polychaetes were collected from the Ponta do Cabo Branco beach, Paraba, Brazil, and represent the first record of the genus Nicomache for the southwest Atlantic. Nicomache ( Nicomache) lanai sp. nov. has 22 setigerous segments, two pre- anal asetigerous segments, a dark beige colour on setigers 4 - 17, an anteriorly rounded prostomium forming a tall, arched keel, elliptical nuchal grooves that open posteriorly, 4 - 7 acicular spines on setigers 1 - 3, and an anal funnel with triangular equal-sized anal cirri, with concave sides. Nicomache ( Nicomache) brasiliensis sp. nov. also has 22 setigerous and two pre-anal asetigerous segments, but the entire body is light-pink coloured. The prostomium is rounded anteriorly, but is longer, broadening posteriorly, forming a low, straight subterminal keel. This species has parallel nuchal grooves, with a sharp anterior angle, has only 4 - 6 acicular spines on setigers 1 - 3, and an anal funnel with short tapering, equal-sized anal cirri with convex sides.
