The genus
Nauphanta, described to contain the species
novaeaehollandiae (as
novae Hollandiae) and
corallina, is now considered a synonym of
Marphysa. Examination of the types has demonstrated that the two species do not belong to the same genus.
Nauphanta novaehollandiae has simple, capillary setae and series of large, flat, thin fan-shaped setae arranged in a row on the anterior face of far posterior parapodia and lacks compound setae.
Nauphanta corallina is a member of
Marphysa in that it has compound falcigers in addition to simple setae and has true pectinate setae mixed with the limbate setae in the dorsal fascile.
Nauphanta is here defined in relation to
Marphysa.
Eunice mossambica Peters, 1854, is newly referred to
Nauphanta.
