LEAFHOPPERS (HOMOPTERA, CICADELLIDAE) FROM DOMINICAN AMBER

Three species of Cicadellidae from Dominican amber-Krisna garciamarque zi, new species (Krisnini), Krocarites reflexa, new genus, new species (Nirvanini), and Jassoqualus hispaniolensis, new species (Nirvanini)- are described and illustrated, and represent the first known fossil re presentatives of these two tribes. Nirvanini and Krisnini are not know n to occur presently on Hispaniola. Descriptive notes are given for fo ssil species in the subfamilies Agalliinae, Cicadellinae, Typhlocybina e, and Xestocephalinae. Comparison of fossil leafhoppers from the Tert iary period to those known from the Cretaceous suggests that much subf amily-through genus-level diversification occurred between the late Cr etaceous and middle Tertiary, and that modern genera existed as early as 55 million years ago.
