The Japanese Cinara shinjii Inouye, was occasionally collected in a private garden in Raddusch-Spreewald (Brandenburg), Germany, on an ornamental Japanese white pine, Pinus parviflora Siebold & Zucc. The species is redescribed providing morphological data of apterae, alatae virginoparae and oviparae females, in order to facilitate morphological identification. This finding, that represents the first record of C. shinjii in Europe, is evaluated in the context of the emerging issue represented by biological invasions. A brief overview of Cinara species alien to Europe is presented with a short critical analysis of their distribution as well as of their ecological and economic impact
