New genera and species from the Equatorial Pacific provide phylogenetic insights into deep-sea Polynoidae (Annelida) Author Bonifácio, Paulo Author Menot, Lénaïck text Zoological Journal of the Linnean Society 2019 185 555 635 journal article 0024-4082 74C07292-2BD6-4E3E-B68D-B144B81BBD83 BATHYLEVENSTEINA PETTIBONE, 1976 Type species: Bathylevensteina bicornis ( Levenstein, 1962 ) . The genus is monotypic. The type species was originally described as Macellicephala by Levenstein (1962) , who described a particular shape of the prostomium, ending with ‘bifurcate frontal horns’. Pettibone (1976) incorrectly considered these frontal horns as lateral antennae inserted medially. Later, Pettibone (1994) corrected this interpretation and placed Bathylevensteina within the subfamily Macellicephalinae .
