Abstract
- Two new extinct fossil cicadellid taxa from Eocene Baltic amber, representing the subfamily Eurymelinae (sensu lato), are described and illustrated, and their relationships to modern leafhoppers are discussed. Eoidiocerus emarginatus gen. and sp. n. is the oldest known representative of the tribe Idiocerini. The new genus resembles some modern Afrotropical and Indomalayan idiocerine genera but differs in having the gena relatively narrow. Archipedionis obscurus gen. and sp. n., is the first well-preserved fossil representative of Macropsini to be described in detail. Previous reports of this tribe from Baltic amber, while credible, included too little morphological information to assess their relationships. Additional comparative notes are provided for previously described fossil taxa belonging to Idiocerini and Macropsini from the Oligocene of Germany. The new combinations Oncopsis sepultus sepultus (Statz, 1950), comb. n. and Oncopsis sepultus austerus (Statz, 1950), comb. n. are proposed for taxa previously included in Bythoscopus Germar. The previously unplaced cicadellid fossil taxon Priscacutius denticulatus Poinar & Brown, 2018 from mid-Cretaceous Myanmar amber is newly placed in subfamily Signoretiinae, tribe Phlogisini, and represents the oldest known member of this subfamily, the only one known from the fossil record and only the second modern cicadellid subfamily confirmed by direct fossil evidence to have been present during the Cretaceous period.
