The whiteflies (Hemiptera : Aleyrodidae) of Europe and the Mediterranean Basin

The whitefly fauna of Europe and the Mediterranean Basin comprises 56 speci es that are considered to be native or naturalized, accommodated within 25 genera. Presented here are a check-list, an identification key to puparia, and a brief account of each species including its distribution and host-pla nt range. The puparium of each species is illustrated. One new nomenclatura l combination (Aleuroclava similis, from Aleurotuberculatus) and two new sy nonymies (Parudamoselis kesselyaki with Ceraleurodicus varus, Asterobemisia nigrini with A. paveli) are proposed. Three nominal species (Aleurodes cap reae, A. fraxini, and Aleyrodes campanulae) are here treated as nomina dubi a. Species which, in the study area, have only been recorded from glasshous es are discussed. Four additional species, not yet recorded from the region , are included in the discussion, two of them because a particular quaranti ne risk is perceived and two because they are notifiable pests in European Union quarantine legislation.
