A revised description of Psyllopsis repens Loginova, 1963 (Hemiptera: Psylloidea: Psyllidae), with first records from Europe

Abstract

Psyllopsis repens Loginova, 1963 (Hemiptera: Psylloidea: Psyllidae: Diaphorininae) is recorded for the first time from Europe from two localities within the city of Belgrade in Serbia. This jumping plant-louse species is narrowly oligophagous on several ash-tree species (Fraxinus angustifolia, F. excelsior, and F. ornus) and induces galls on leaves and buds. Previously, it was known only from the Caucasus and the Middle East. We provide detailed morphological descriptions and illustrations of adults and the fifth instar larva, and summarize available information on the biology, distribution, and economic importance of P. repens.
