Abstract

Individuals belonging to two new species, from two genera Clymenella Verril (Maldanidae) and Mooreonuphis Fauchald (Onuphidae), have been collected and described from a sublittoral bottom area close to Antofagasta, northern Chile. The environment consists of medium to fine sands and the samples have been collected at ca. 60 m depth. Clymenella fauchaldi sp. n. is closely related to Clymenella minorArwidsson, 1911, but clearly differs from other species of the genus in the type of notochaetae, winged capillaries, and neurochaetae, thick acicular spines, that are borne on the first chaetigers. Mooreonuphis colosensissp. n.is related to Mooreonuphis nebulosa (Moore, 1911) and Mooreonuphis peruana (Hartman, 1944), but differs mainly in the form of the mandibles, in the maxillary formula, location of the subacicular hooks on chaetigers, number of the ceratophore rings and the length of the medium and lateral antennae styles.
