A New Species of Tympanoterpes Stål, 1861 (Hemiptera: Cicadidae: Fidicinini) from Brazil Including Notes on Bioacoustics, Natural History, and Adult Behavior

Tympanoterpes merganota sp. nov. is described and illustrated. Notes on natural history and adult behavior are presented including the description of the acoustic repertoire. This new species is currently endemic to Brazil, occurring in shrublands in the Atlantic Forest and Pampa regions.

Adults have been observed in association with Asteraceae shrubs, using these plants as calling, copula, and oviposition sites. These results were achieved with the contribution of citizen science, proving its importance as an auxiliary tool for researchers.
