Gabriel Mejdalani, Alexandre C. Domahovski, Diana I. Rendón-Mera, Rodney R. Cavichioli


Two new Brazilian sharpshooter species of the genus Tretogonia Melichar, 1926 are described and illustrated: Tretogonia diminuta sp. nov. and T. elegantula sp. nov., both from the State of Paraná. A redescription of T. dentalis Emmrich, 1988 is provided based on a male from the State of Mato Grosso do Sul. This is the first Brazilian record of T. dentalis, a species originally described from Paraguay. Photographs and line drawings are provided for the three species, as well as notes on the taxonomy and biology of the genus.
