Guineapsaltria, a new genus from the Australian — New Guinean region (Homoptera, Tibicinidae), with notes on its taxonomy and biogeography

The genus Guineapsaltria is erected for eight species, distributed in New Guinea and northeastern Queensland. Five species are transferred from the genus Baeturia Stål, 1866 and redescribed, viz. G. chinai (Blöte, 1960), G. flava (Goding & Froggatt, 1904), G. pallida (Blöte, 1960), G. stylata (Blöte, 1960), and G. viridula (Blöte, 1960), while three species are described as new to science (G. flaveola n. sp., G. pallidula n. sp., and G. pennyi n.sp.). G. flava is designated as the type species of the genus. Baeturia minuta Blöte, 1960 is synonymized with Guineapsaltria flava. The phylogeny of Guineapsaltria is discussed and some remarks are made on its phylogenetic relationships with other New Guinean and Australian tibicinid genera. A key to the males and maps of distribution are presented.
