Abstract

Eight exotic species of Cicadellidae apparently recently established in Hawaii are newly recorded. Four species belonging to subfamily Typhlocybinae, tribe Dikraneurini: Idona minuenda (Ball), native to Mexico and the Caribbean; Typhlocybella minima Baker, native to the Caribbean Basin from the southeastern United States to northern South America; Dikraneura absenta DeLong & Caldwell, is widespread in temperate North America west of the Rocky Mountains where it is reported to injure grasses, clover, and alfalfa; and Parallaxis yeeae n. sp. (Dikraneurini), representing the first record of the genus from Hawaii. Other new Hawaiian genus and species records are: Eupteryx decemnotata Rey (Typhlocybinae: Typhlocybini), native to Europe but recently established in Florida and California, which feeds on various species of Lamiaceae including several economically important herbs; Empoasca fabalis DeLong (Typhlocybinae: Empoascini), a pest of sweet potato and various legumes (Fabaceae) with a native range extending from the southern continental United States to Argentina but also established in Madeira and the Canary Islands; Anoscopus albifrons albifrons (L.) (Aphrodinae: Aphrodini), native to Europe but also established on the east and west coasts of temperate continental North America; and Ollarianus strictus (Ball) (Deltocephalinae: Athysanini), native to the southwestern United States and Mexico but recently introduced into Florida.
