桦树和赤杨属Euceraphis饲养蚜虫的样品进行了测量和分析，使用多重判别分析（典型变量），以找出是否形态变化与以前报道的核型和主机协会的差异。该数据集由仅按地点和采集日期定义的标本组组成。前两个典型变量的平均得分聚类样品完全按照其核型和宿主植物，确认存在一些形态相似，但不同的主机特定类群内的E。桦木群描述了三个新种：北方真针蚁Euceraphis borealis Blackman，sp. n.腺桦和B. nana，纸蚜Euceraphis papyrifericola Blackman，sp.n.在B。papyrifera和QuednauiBlackman，sp.n.在B。[咒语]提供了该属有翅胎生动物检索表。
Samples of birch- and alder-feeding aphids of genus Euceraphis were measured and analysed using multiple discriminant analysis (canonical variates) to find out if morphological variation correlated with previously reported differences of karyotype and host association. The dataset comprised groups of specimens defined solely by locality and collection date. Mean scores on the first two canonical variates clustered the samples fully in accordance with their karyotypes and host plants, confirming the existence of a number of morphologically similar but distinct host-specific taxa within the E. betulae group. Three new species are described: Euceraphis borealis Blackman, sp.n. on Betula glandulosa and B. nana, Euceraphis papyrifericola Blackman, sp.n. on B. papyrifera, and Euceraphis quednaui Blackman, sp.n. on B. occidentalis. A key is provided to alate viviparae of the genus.
