Betulaphis pelei Hille Ris Lambers
Material. NNV: 14.viii.1977, sweeping, al. ( AB).
Boernerina alni Takahashi
Published information. Ivanovskaya (1977) indicates that an alate viviparous female was found in Talnakh ( NUO) in July. She identified this specimen as Boernerina depressa Bramstedt. However, the study of the corresponding slide from her collection showed that in fact this alatae belongs to the species Boernerina alni Takahashi. Thus, Boernerina depressa should be excluded from the list of species found on Taymyr.
Material. NNV: 14.viii.1977, sweeping on Salix sp., ovip. ( AB). NDU: 1.vii.2017, Alnus alnobetula subsp. fruticosa (Rupr.) Raus, on lower side of leaves, imm. [ 5–8.vii.2017, apt. and al.] ( AS). NUO: near to Talnakh, 20.vii.1964, Alnus sp., al. ( EI).
Comments. The collected specimens are similar to Boernerina alni insularia Pashtshenko with regards to the ratio of the length and width of the 1st antennal segment and the number of setae on the ultimate rostral segment, as well as the absence of sclerotized bands on the abdomen of the alatae. At the same time, they have, in common with Boernerina alni alni Takahashi, a short ultimate rostral segment and the length of the posterior femora is almost equal to or greater than the width of the head through the eyes.
Calaphis flava Mordvilko
Material. NDU: 7.vii.2017, Betula nana L., on lower side of leaves, imm. [ 10.vii.2017, apt. and al.] ( AS). NUO: near to Valyok Vill., 19.vii.2017, Betula sp., on lower side of leaf, al. ( AS).
Euceraphis betulae (Koch)
Material. MEB: 17–22.vii.2002, biotopes with various tundra vegetation, pitfall traps, al. ( MB). NDU: 3.vii.2017, Betula nana, sweeping, al. ( AS). NUO: near to Valyok Vill., 19.vii.2017, Betula sp., on lower side of leaves, al. ( AS).
Comments. In northwestern Taymyr ( MEB), the aphids were apparently transported by wind, as there are no host plants (birches) in this area ( Matveyeva & Zanokha 1997).
Euceraphis betulijaponicae (Matsumura)
Material. NDU: 1.vii.2017, Alnus alnobetula subsp. fruticosa, on lower side of leaf, al. ( AS).
Euceraphis punctipennis (Zetterstedt)
Published information. Near to Norilsk (Talnakh), on Betula sp. ( Ivanovskaya 1977).
Material. MEB: 17–22.vii.2002, biotopes with various tundra vegetation, pitfall traps, al. ( MB). TAM: 21.vii.2010, wet depression with thickets of willow and birch bushes, sweeping, al. (OKh). NDU: 3.vii.2017, Betula nana, sweeping, al. ( AS). NUO: near to Talnakh, 24.vii.1964, Betula nana or sweeping, al. ( ЕI); near to Valyok Vill., 19.vii.2017, Betula sp., on lower side of leaves, al. ( AS).
Comments. In northwestern Taymyr ( MEB), the aphids were apparently transported by wind, as there are no host plants (birches) in this area ( Matveyeva & Zanokha 1997).
