Type species: Polydora cornuta Bosc, 1802 , by monotypy.
Diagnosis
Prostomium entire or incised, extending posteriorly as a caruncle, surrounded by nuchal organ. Chaetiger 1 without notochaetae. Chaetiger 5 greatly modified, with major spines of one type in a single curved row, usually accompanied by slender companion chaetae. Posterior notopodial spines present or absent. Neuropodial hooded hooks bidentate from chaetigers 7–14, with conspicuous angle between teeth, with constriction on shaft. Branchiae begin posterior to chaetiger 5. Pygidium variable: cuff-shaped, cup-shaped or disc-like with dorsal gap, lobed, scoop-shaped, or with digitiform cirri.
Remarks
Polydora was reviewed by Blake (1996); he divided the species into five groups and recognized 31 species; with the new species described by Williams (2001), Radashevsky and Pankova (2006) and Radashevsky et al. (2006), there are now 36 species.
