Introduction The fossil record of leafboppers (Cicadellidae), as reported in the literature, is very sparse, consisting of a few reports of rock fossils from the lower Cretaceous of Brazil and Australia (Hamilton 1990, 1992), a single wing impression from the upper Cretaceous of western North America (Oman 1937), several genera and species from Eocene Baltic amber (Szwedo 2002) and several genera and species from Oligo-Miocene Dominican amber.Known Cretaceous leafhopper fossils are mostly either too poorly preserved to facilitate placing them to subfamily or, with the exception of two Brazilian fossils placed in Ledrinae, have generalized morphology indicating that they do not belong to modem groups.
