The Psylloidea (Hemiptera) of Portugal (mainland, Azores and Madeira): checklist and new distributional and host records

The occurrence of 71 species of Psylloidea in Portugal (mainland and islands) is documented based on a critical review of literature sources and the examination of recently collected and museum material. The following 17 species are reported from Portugal for the first time: Acizzia acaciaebaileyanae, Aphalara polygoni, Arytaina genistae, Arytainilla delarbrei, Bactericera nigricornis, B. substriola, B. trisignata, Cacopsylla alaterni, C. perrieri, Colposcenia tamaricis, Livia mediterranea, Livilla maculipennis, Macrohomotoma gladiata, Psylla foersteri, Psyllopsis fraxinicola, Trioza centranthi and T. eugeniae. Among the literature records reviewed, four are questionably assigned to particular psyllid genera or species, two probably refer to psyllids and six probably do not concern psyllids. Five species records in the literature are erroneous even though some of the species may occur in Portugal. The following synonymies are proposed: Bactericera Puton, 1876, = Phylloplecta Riley, 1884, syn. nov., = Sinitrioza Yang & Li, in Li & Yang, 1984, syn. nov. These synonymies entail following new or revived combinations: Bactericera chunghsingica Lauterer, Yang & Fang, 1988, comb. rev.; B. occidentalis (Tuthill, 1939) comb. nov.; B. rubicola (Tuthill, 1943) comb. nov.; B. rubisuga (Yang & Li, in Li & Yang, 1984) comb. nov.; B. stylifera (Patch, 1912) comb. nov.; B. tripunctata (Fitch, 1851) comb. nov. and B. trisignata (Lw, 1886) comb. rev. While the fauna of Madeira is relatively well documented, this is not the case for that of the Azores and particularly of the mainland.
