 Maisch & Matzke, 2000 considered both Russian taxa to be synonyms of each other, and referred the new combination "B. pseudoscythica" to "Brachypterygius", although they misspelt this as "B. pseudoscythius".Thus, "Grendelius" and "Otschevia" are considered to be junior synonyms of "Brachypterygius".Arkhangelsky named "Otschevia alekseevi" in 2001, also from the Late Jurassic of Russia.
