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 has not been reported early from Chilean coast. Pettiboneia n. sp. is related to P. sanmatiensis Orensanz, 1973 and P. urciensis Campoy & San Martín, 1980, but differs from these species in the shape of mandibles, maxillae, setae, and especially in forked setae. Protodorvillea n. sp. is close to P. kefersteini (McIntosh, 1869) but differs from this species in the shape of the forked setae, in having posterior simple setae markedly curved and lacking cultriform setae.
