Euceraphis sp.

Material. NDU: 3.vii.2017, Betula nana , sweeping, al. ( AS) . NUO: near to Talnakh, 24.vii.2017, Alnus alnobetula subsp. fruticosa , on lower side of leaves, al. ( AS) .

Comments. These aphids are not identifiable to specific level with the existing keys to the genus Euceraphis ( Blackman & De Boise 2002; Blackman & Eastop 2019) because several features are intermediate and are located between the values specified in the key couplets. The small number of specimens prevents deciding whether these characteristics represent intraspecific variation or the collected specimens belong to a previously unknown taxon.
