Taxonomy
edit.JPG)
Cottocomephorus was first proposed as a monospecific genus in 1900 by the French ichthyologist Jacques Pellegrin when he described Cottocomephorus megalops as a new species.[1] The genus was classified in the family Cottocomephoridae; however, the 5th edition of Fishes of the World classifies the genus within the subfamily Cottinae of the family Cottidae, studies having found that the genera formerly included in the Cottocomephoridae were a clade arising from the genus Cottus.[4]
Species
editThere are currently three recognized species in this genus:[2]
- Cottocomephorus alexandrae Taliev, 1935
- Cottocomephorus grewingkii (Dybowski, 1874) (Baikal yellowfin)
- Cottocomephorus inermis (Yakovlev, 1890) (Longfin Baikal sculpin)
