Abstract

The most relevant morphometric characteristics of six species of the genus Anuraphis Del Guercio were compared. Anuraphis shaposhnikovisp. 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.

Résumé

On trouvera ici une comparaison des caractères morphométriques les plus pertinents de six espèces d'Anuraphis Del Guercio, ainsi que la description d'Anuraphis shaposhnikovisp. nov. et des caractéristiques morphologiques qui le distinguent d'Anuraphis subterranea, une espèce très apparentée. La nouvelle espèce a été récolté en Sicile et dans la région centrale de la péninsule italienne sur Magydaris pastinacea (Lam.) Paol. (Apiaceae) et sur Opopanax chironium (L.) Koch (Apiaceae) qui sont ses hôtes secondaires. Un clé permet l'identification des formes vivipares (aptères et ailées) des sept espèces de la région paléarctique occidentale qui vivent sur des hôtes secondaires. Des fonctions discrimantes facilitent la séparation des formes aptères et ailées d'A. shaposhnikovi et d'A. subterranea.
