Zaniolepis was first proposed as a
monospecific genus in 1858 by the French
zoologist Charles Frédéric Girard when he
described Z. longispinis from
Fort Steilacoom on
Puget Sound in
Washington. Zaniolepididae was first proposed as a family in 1883 by the American ichthyologists David Starr Jordan and Charles Henry Gilbert. this taxon was previously classified as the subfamily Zaniolepinae within the
Hexagrammidae. This family is classified within its own
superfamily, the Zaniolepidoidea, within the
suborder Cottoidei of the
Scorpaeniformes. Other workers have found that if the Scorpaeniformes, as delimited in
Fishes of the World, is not included in the
Perciformes it renders the Perciformes
paraphyletic. These workers retain the Cottoidei as a suborder within the
Perciformes while reclassifying Zaniolepidoidea as the
infraorder Zaniolepidoales. Presently, ''
Eschmeyer's Catalog of Fishes'' keeps the Zaniolepididae as a family of the Cottoidei in Perciformes. Previously, the painted greenlings in
Oxylebius were also classified in the family Zaniolepididae. However, such a placement is paraphyletic with respect to Hexagrammidae, and so the
Catalog of Fishes retains
Oxylebius in the Hexagrammidae. ==Etymology==
