A new species of uroleucon (hom. aphididae) on andryala spp: a multivariate analysis

Abstract

A study of different biometrie data of populations of Uroleucon (U.) picridis (F., 1775) sensu lato using canonical discriminant analysis resulted in the separation of two morphological groups. Exchange of host plants allowed us to conclude that the two groups correspond to two different species: Uroleucon (U.) picridis and Uroleucon (U.) mierae sp.nov. This latter species was described and a key to the identification of both species was given.
