Studies of material of Betlllaphis brevipilosa Börner, 1940, collected by Börner in 1939 and believed to be syntypes, have shown that the species called brevipilosa by Börner is the same taxon as B. quadrituberculata subsp. helvetica Hille Ris Lambers, 1947, later given species rank as B. helvetica. The latter name is a junior synonym of brevipilosa. A lectotype has been selected. The other specimens have been labelled paralectotypes.
