Abstract
Sitobion (Metobion) graminearum (Mordvilko, 1919) is redescribed based on type material, earlier published data and new material. A lectotype is designated and data provided on the distribution and biology of the species. Sitobion (Metobion) graminearum (Mordvilko, 1919) was described as Acyrthosiphon (Metopolophium) graminearum from a few oviparous females and males taken near Petrograd (now St. Petersburg), Russia, at Razdel'naya (now Lisiy Nos) railway station. The aphids were collected by Mordvilko from leaves of an unidentified grass on 23.ix. 1913. Hille Ris Lambers (1947) recognised Metopolophium as a full genus, and Metopolophium graminearum was subsequently recorded from the Eastern Alps by Borner (1952), and from Hohe Tauern by Borner & Franz (1961).
