Onuphis Audouin & Milne Edwards, 1833

Type species: Onuphis eremita Audouin & Milne Edwards, 1833: 226 by subsequent designation of Malmgren 1866: 180.

Type locality. Off La Rochelle, Eastern France, Atlantic Ocean.

Diagnosis. Prostomium often anteriorly extended; with frontal lips. Antennae and palps with ceratophores with 10–25 rings and short to moderately long styles, palpal styles shorter than their ceratophores. Nuchal grooves straight. Peristomial cirri present. Anterior three to four (rarely two or five) pairs of parapodia modified but not enlarged. Ventral cirri subulate on anterior four to six chaetigers; dorsal cirri moderately long. Branchiae rarely absent, usually present from chaetiger 1, rarely 3–6; single or pectinate filaments (maximum 12). Hooks of modified parapodia usually tridentate (rarely only bidentate, sometimes bi- to multidentate) pseudocompound with short hoods; median hook slightly larger but not becoming simple and changing to large median hook. Dorsal limbate chaetae from chaetiger 1, ventral limbate chaetae replacing pseudocompound hooks from chaetiger 4 or later until replaced by bidentate hooded subacicular hooks usually from chaetiger 10–12. Tubes round in section, ranging from thin mucous to tough parchment-like inner layer covered with extraneous particles.
