Diagnosis. Ipamerica auctuncus is the only representative of the genus; it is most similar to Ricula trechalea Razowski & Becker, 2012 from Pará, Brazil, from which it differs by having a distinct incision of the termen beneath the apex of the forewing and in the reduction of the terminal row of spots.

Forewing ( Fig. 14 ) cream sprinkled and suffused with pale brown; costal strigulae whitish; divisions brown; leaden grey lines from costa and subterminal area; dorsal patch indistinct accompanied by several similar lines chiefly towards wing base; distinct black spots in ocellus. Cilia pale brownish, basal line brown. Hindwing brownish. Cilia paler. Abdomen: Male genitalia ( Fig. 2 ) as described for the genus. Female unknown.

Distribution and biology. Known from the states of Goias and Distrito Federal, Brazil.
