Genus Pectinaria Lamarck, 1818

Pectinaria Savigny in Lamarck, 1818: 348.— Hartman 1941: 329; Hartman 1959: 479; Fauchald 1977: 120; Holthe 1986: 20 – 21.

Type-species. Nereis cylindraria belgica Pallas, 1766 , designated by Hartman (1959).

Diagnosis. (After Hutchings & Peart 2002; Nishi et al. 2014). Rim of cephalic veil with numerous long cirri. Cephalic veil completely free from operculum, forming a dorsal semi-circular lobe covering the bases of numerous buccal tentacles. Raised opercular margin smooth. Chaetigers 1–3 (segments 5–7) with notopodia and notochaetae only, chaetigers 4–16 biramous with notopodia, neuropodia, notochaetae and neurochaetae, chaetiger 17 with notopodia and notochaetae only (ratio of number of pairs of notopodia to neuropodia 17/13). Notochaetae smooth or serrated (or plumose). Neurochaetal uncini with major teeth arranged in two or three (or more) rows. Posterior 5 segments fused to form a flattened plate or scaphe distinctly separate from the abdomen.

Remarks. Twenty-four species of Pectinaria have been described to date. The major Australian revision by Hutchings & Peart (2002) listed 22 species, Nishi et al. (2014) re-established P. hiuchiensis Kitamori, 1965 and transferred P. okuda ( Imajima & Hartman, 1964) from the genus Cistenides . An additional species is described in this paper.
