Notes on the Species of Aspidaphium Börner, 1939 (Homoptera: Aphididae).

Abstract

The author examines the morphological characters of the European species of Aspidaphium, with special reference to the Börner type specimens and to more recent British material. The name Aspidaphium jeschkei G. B. becomes a synonym of A. escherichi G. B. The author further offers a key for the identification of the British species of the genus Aspidaphium G. B.
