Etymology: Radulinopsis: Latin, radula, radere = to scrape (1877) (Ref. 45335); taranetzi: Named after the late Anatoly Yakovlevich Taranetz, in recognition of the understanding of boreal fishes and especially cottoid classification (Ref. 45337).
Eponymy: Anatoly Yakovlevich Taranetz (1910–1941) was a Russian marine biologist and ichthyologist who was an eminent expert on Far Eastern fishes. [...] (Ref. 128868), visit book page.
