Abstract

new pygmy unicorn genus, Brazitettix Silva, new genus, and two new species, Brazitettix roraimae Silva, new species and Brazitettix paulista Silva, new species (Orthoptera: Caelifera: Tetrigidae) are described in Brazil. This new genus is a unique tetrigid taxon in the American continent due a notched-long and elevated head projection. The morphology of this taxon resembles Rostella Hancock, 1913 and Dravidac¬ris Bhaskar and Kasalo, 2022 that are currently comprised into Cleostratini, an artificial group that contains biogeographic distant taxa with distinct morphological head projection.

Resumen

Un nuevo género de tetrígidos, Brazitettix Silva, nuevo género, y dos nuevas especies, Brazitettix roraimae Silva, nueva especie y Brazitettix paulista Silva, nueva especie (Orthoptera: Caelifera: Tetrigidae) se describen de Brasil. Este nuevo género es único en el continente Americano debido a la presencia de una proyección larga y elevada en la cabeza. La morfología de este taxón se asemeja a Rostella Hancock, 1913 y Dravidacris Bhaskar and Kasalo, 2022, que actualmente forman parte de Cleostratini, un grupo artificial que contiene grupos biogeográficos distantes y con distintas proyecciones morfológicas en la cabeza.
