Katydids (Orthoptera: Tettigoniidae) from Guartelá State Park, State of Paraná, Southern Brazil: diversity, bioacoustics and description of five new species.

Tettigoniidae is the most diverse family within Orthoptera; its species inhabit forests all over the world, with the tropical and subtropical forests hosting the greatest number of species. Brazil is the country with the largest remnants of preserved forests, and is the country with the most recorded species of katydids. Even so, only two faunistic inventories have been carried out, both in the Atlantic Forest. The main objective of this work was to provide a faunistic inventory of Tettigoniidae in the Guartelá State Park, Paraná State, Southern Brazil, a park that preserves both the Atlantic Forest and Cerrado biomes. In this contribution 57 species of Tettigoniidae were recorded, with Phaneropterinae being the most diverse subfamily, represented by 36 species; Conocephalinae was represented by 19 species, whereas Meconematinae and Pseudophyllinae had only one species each. Among these species, five are new and are herein described: Conocephalus (Anisoptera) guartela sp. nov. (Conocephalinae: Conocephalini), Anaulacomera (Cervicercora) melloi sp. nov., Anaulacomera (Anaulacomera) szinwelskii sp. nov. (Phaneropterinae: Phaneropterini), Anisophya hemanuelae sp. nov., and Xenicola nunoi sp. nov. (Phaneropterinae: Odonturini). The calling songs of three of the new species were also recorded and are herein described and discussed, as well as the sounds of all species of the subgenus Conocephalus (Anisoptera). The relationship of some katydid species to plants is also described and discussed, as well as the feeding habits and other aspects of natural history, and the presence of some species in the driest areas of the park, representing the Cerrado, the biome with the lowest number of tetigonids recorded so far.
