. Multivariate morphometric analysis (canonical variates) was used to discriminate between closely related taxa within the Myzus persicae group. It is demonstrated that dark green, anholocyclic populations with a 2n=13 or 2n=14 karyotype in Europe, hitherto treated as a form or biotype of M.persicae, all conform to a discrete morphometric grouping and should therefore be treated as a separate taxonomic entity, permanently isolated from the M.persicae gene pool. It is suggested that this taxon was first described as Siphonophora antirrhinii by Macchiati in 1883. A discriminant function is provided to separate most individual apterae of antirrhinii from those of persicae. Myzus icelandicus Blackman sp.n., on Caryophyllaceae and other plants in Iceland, is distinguished from M.polaris H.R.L. and M.certus (Walker), and a key is given to apterous virginoparae of the species of the M.persicae group in Europe.
