Karyotype variation within the genus Glyphina in Europe is described and correlated with morphological differences. G.pseudoschrankiana sp.nov., on Betula pubescens in Europe and Japan, is separated form G.schrankiana Börner, on Alnus spp. in northern and central Europe, on the basis of differences in karyotype and morphology. G.jacutensis Mordvilko is synonymized with G.schrankiana. A key is provided to palaearctic members of the genus.
