Eryngiofaga perrara sp. nov. (Hemiptera, Psylloidea) from Mount Pilatus (Obwalden), a new species of a genus previously unknown from Switzerland or the Alps

Eryngiofaga perrara sp. nov. is described, diagnosed and illustrated from two adult specimens found on Mount Pilatus (Switzerland, Obwalden). The new species is morphologically most similar to E. matura (Loginova, 1972), a species from Mongolia, from which it differs in the light genal processes and in details of the terminalia. Eryngiofaga consists of 13 previously described species of which five occur in Central and Western Europe. Up to now, the genus was not known from Switzerland or the Alps. The host plant of E. perrara remains unknown, but Bupleurum ranunculoides L. (Apiaceae) is a likely candidate.
