Two new species of small dorvilleids, belonging to the genus Pettiboneia Orensanz and Protodorvillea Pettibone, have been collected and described from a sublittoral sandy soft-bottom area near Antofagasta, northern Chile. Both genera had not been reported previously from Chilean coast. Pettiboneia wui n. sp. is related to P. sanmatiensis Orensanz, 1973 and P. urciensis Campoy and San Martín, 1980, but differs from these species in the shape of the mandibles, maxillae, including sclerotized elements with long and curved spines, setae, and especially forked setae. Protodorvillea orensanzi n. sp. is close to P. kefersteini (McIntosh, 1869) but differs from this form mainly in the shape of parapodia, forked setae, and especially from mandibles and maxillae, the latter presenting large and curved superior free denticles.
