Morphological discrimination of six species of the genus Anuraphis (Hemiptera: Aphididae) including description of a new species

The most relevant morphometric characteristics of six species of the genus Anuraphis Del Guercio were compared. Anuraphis shaposhnikovi sp. nov. is described and its morphological differences from the closely related species Anuraphis subterranea are presented. The new species was collected in Sicily and in the central area of the Italian peninsula on Magydaris pastinacea (Lam.) Paol. (Apiaceae) and Opopanax chironium (L.) Koch (Apiaceae), which are its secondary host plants. A key to the viviparous morphs (apterae and alatae) of the seven western Palaearctic species living on secondary hosts is provided. Discriminant functions have been derived to separate both apterae and alatae of A. shaposhnikovi and A. subterranea.
