Genus Naineris Blainville, 1828 Naineris Blainville, 1828. Type-species: N. quadricuspida (Fabricius, 1780), by monotypy. Anthostoma Schmarda, 1861. Preoccupied. Type-species: Anthostoma ramosum Schmarda, 1861 ( = Naineris laevigata ), designated by Pettibone (1957). Lacydes Kinberg, 1866. Preoccupied. Type-species: Lacydes havaicus Kinberg, 1866 (= Naineris laevigata ), by monotypy. Polynaineris Pettibone, 1957. Type-species: Naineris laevigata (Grube, 1855), by original designation. Variant spellings . Naidonereis Malmgren, 1867; Nainereis Mesnil & Caullery, 1898; Naidoneris Webster & Benedict, 1887. Diagnosis. Prostomium rounded or truncate on anterior margin. Peristomium with 1–2 achaetous rings. Thorax with 12–30 or more segments; branchiae first present from setiger 2–23. Thoracic neuropodia with 0–2 postsetal lobes; no subpodial lobes. Thoracic neurosetae including capillaries, or capillaries mixed with blunt-tipped uncini, sometimes hooded, or uncini and subuluncini. Abdominal setae including capillaries and sometimes furcate setae in notopodia and capillaries and imbedded or protruding aciculae in neuropodia. Paired dorsal sensory organs present in some species. Remarks. The following six species of Naineris were encountered and are treated in this paper: N. setosa (Verrill, 1900); N. furcillata , new name for N. chilensis Carrasco, 1977; N. chilensis , new status for N. dendritica chilensis Hartmann-Schröder, 1965; N. grubei (Gravier, 1908); N. argentiniensis , n. sp. N. antarctica , n. sp. The holotype vial of N. brevicephala Hartmann-Schröder, 1960 from Peru was examined and found to contain a syllid. Until the actual type specimen is located, N. brevicephala is best treated as incertae sedis . Remarks on the genus Protoariciella Hartmann-Schröder, 1962a . Protoariciella was established for a small orbiniid that had two peristomial rings, and no distinct body regions, but has neuropodial uncini on a defined number of anterior setigers. The genus currently includes five species: P. uncinata ...
