Etymology Chamberlin (1919: 333) gives the translation from Greek of Cenogenus in a footnote as 'strange jaw'. Ceno- is more usually translated as new or recent (as in Eocene, Cenozoic), or perhaps new in the sense of unique. The Greek for jaw is more usually transliterated to Latin as 'genys' '-genyos', a feminine noun. [details]

Status Carrera-Parra (2001) revalidated Cenogenus Chamberlin, 1919 from former synonymy under Lumbrineris and invalidated Paraninoe Levenstein, 1977. He placed Paraninoe fusca, the type species of Paraninoe (as Ninoe fusca), in Cenogenus, and recombined the following species by stating that "Following the list of species provided by Levenstein (1977) and Orensanz (1990), the species of Cenogenus includes C. abyssalis (Imajima & Higuchi, 1975), C. antarctica (Monro, 1930), C. brevipes (McIntosh, 1903), C. descendens Chamberlin, 1919, C. fusca (Moore 1911), C. fuscoides (Fauchald, 1970), C. hartmanae (Levenstein, 1977), C. monotentaculata (Averincev, 1972), C. nagae (Gallardo, 1968), and C. simpla (Moore, 1905)."

Diagnosis Single small antenna in nuchal fold. Setae include limbate capillaries, limbate robust, and simple multidentate hooded hooks. Anterior segments with a parapodial branchia dorsal and posterior to parapodia. Maxillary apparatus and labidognath type; with four pairs of maxillae, maxillae I forceps-like with smooth edges and bridles poorly developed, maxillae II of similar length to maxillae I, maxillae III and IV edentate plates (maxillae V absent); mandibles partially fused. [emended diagnosis of Carrera-Parra, 2001] [details]Etymology Chamberlin (1919: 333) gives the translation from Greek of Cenogenus in a footnote as 'strange jaw'. Ceno- is more usually translated as new or recent (as in Eocene, Cenozoic), or perhaps new in the sense of unique. The Greek for jaw is more usually transliterated to Latin as 'genys' '-genyos', a feminine noun. [details]
Grammatical gender Cenogenus is evidently feminine. The Greek word for 'genus' meaning jaw (usually genys) is a feminine noun. Subsequent adjectival species names have had feminine endings kept when recombined into Cenogenus. As yet there appears to be no adjectival names named as original combinations in Cenogenus. The species name 'descendens' in the type species C. descendens appears to be derived from a verb. [details]
