A new genus of horn-like tetrigids (Orthoptera: Caelifera: Tetrigidae) from South America

A 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 Dravidacris Bhaskar and Kasalo, 2022 that are currently comprised into Cleostratini, an artificial group that contains biogeographic distant taxa with distinct morphological head projection.
