Katydids (Orthoptera: Tettigoniidae) from the Iguaçu National Park, Brazil

A comprehensive survey of katydids (Orthoptera: Tettigoniidae) in Iguaçu National Park, Brazil—the largest preserve of the Interior Atlantic Forest—revealed a remarkable diversity of 89 species across five subfamilies. Phaneropterinae emerged as the most speciose group with 57 species, followed by Conocephalinae (22), Meconematinae and Pseudophyllinae (four each), and Pterochrozinae (two). Notably, several species were recorded for the first time in Paraná State, southern Brazil, or even the country. The study also documented calling songs for 34 species, including 29 previously unknown to science, providing new insights into the acoustic behavior of these insects. These findings underscore Iguaçu National Park's critical role in maintaining biodiversity but also highlight the potential catastrophic impacts of ongoing threats on its unique ecosystems.
