ABSTRACT
Currently, 15 species of Nephtyidae (Annelida) are known from the Sea of Okhotsk (north-western Pacific). A new user-friendly identification key is presented with a brief description for each species. The taxonomic positions of three closely related species, Nephtys brachycephala Moore, 1903, N. schmitti Hartman, 1938 and N. paradoxa Malm, 1874, are revised. The distributions of two species, Nephtys discors Ehlers, 1968 and N. assignis Hartman, 1950, are discussed.
ABSTRACT
In the present study, four species of Nephtyidae, Aglaophamus juvenalis (Kinberg 1866), Nephtys acrochaeta Hartman 1950, Nephtys californiensis Hartman 1938 and Nephtys squamosa Ehlers 1887, were found from the intertidal zone to the shallow sublittoral (<50 m) off São Paulo, Brazil, during the program BIOTA/FAPESP Marine Benthos. Descriptions and notes on each of them are provided. Nephtys californiensis is a new record for the Brazilian coast. Keys to genera and species of Nephtyidae recorded from Brazil are given.

Descrições e comentários são fornecidos para cada uma delas. Nephtys californiensis é um novo registro para a costa brasileira. Chaves para gêneros e espécies de Nephtyidae registrados no Brasil são fornecidas.
