‘Genus Flabellina sensu latissimo ’ Gosliner and Griffiths 1981: 105 , 109–15.
Family Flabellinopsidae Korshunova et al. 2017a: 23 View in CoL .
Diagnosis: Body relatively wide. Notal edge discontinuous. Cerata on broad extensions, numerous per row. Ceratal rows branched. Rhinophores perfoliate or granulate. Anus pleuroproctic. No elaborate oral glands. Masticatory edges of jaws bear several rows of compound, sharpened, or tubercle-like denticles. Radula formula 1.1.1. Central teeth usually with cusp compressed by adjacent lateral denticles. Lateral teeth narrow or with attenuated process basally, denticulated, or smooth. Distal receptaculum seminis. Vas deferens long, prostate indistinct or distinct. Supplementary and accessory gland absent. Massive external permanent penial collar absent. Penis internal, unarmed.
Genera included: Flabellinopsis MacFarland, 1966 and Baenopsis Korshunova et al., 2017 .
Remarks: Bergh (1904) described a species ‘ Coryphella ’ californica , which is characterized by ringed (although in a preserved state) rhinophores, c. 10 ceratal groups on lateral parts of the back, and a triserial radula with numerous short lateral denticles of the central teeth. The latter character especially is contrary to any radular pattern in any genera of the proper family Coryphellidae (see: Korshunova et al. 2017a, present study Synopsis below). The shape of the radular teeth and number of small numerous denticles ( c. 17) of ‘ Coryphella ’ californica , however, closely resemble Flabellinopsis iodinea (Cooper, 1862) , which inhabits essentially the same geographic region. External characters of ‘ Coryphella ’ californica , taking into consideration that Bergh described a preserved specimen, do not contradict the features described by MacFarland (1966) in the original description of the genus Flabellinopsis and its type species F. iodinea . We propose, therefore, to consider ‘ Coryphella ’ californica as a junior synonym of Flabellinopsis iodinea with a question mark. It is not a contradiction of our methodology consistently presented here, because ‘ Coryphella ’ californica is an old, semi-obscure taxon that obviously possesses a radula, which otherwise is not similar to Coryphellidae , but instead is similar to the distantly related family Flabellinopsidae . Therefore, the continuous usage of ‘ Coryphella ’ californica as a member of the family Coryphellidae will confuse real phylogeographic and taxonomic patterns of coryphellids.
