03A287C10D26FFC4FF1AACABFD58FA75.taxon	discussion	Comments. The new species was found mainly in areas corresponding to the Serra do Mar coastal forests ecoregion and with one record in the Alto Paraná Atlantic forest ecoregion. The distribution in the Serra do Mar is a feature shared by both species of Megatympanon, but M. austroraptorum sp. nov. occurs in a southernmost portion than M. speculatum. Despite the near distribution, we did not find evidence of sympatry between both species. The Serra do Mar coastal forests are characterized by the coastal plains and chain of mountains, ranging from 20 m up to 2000 m of elevation. These differences in altitudes provide differences in climate and vegetation, which allows for great biological diversity in this ecoregion (Carlucci et al. 2021). The Serra do Mar is characterized by a great diversity of large tree species such as Copaifera trapezifolia, Pouteria spp., Chrysophyllum spp., epiphytes, and also species of Myrtaceae and Melastomataceae (Schipper, 2023). That habitat unfortunately has been highly fragmented by anthropic influence, with lowland forests depleted to the construction of urban areas and to slash-and-burn agriculture (Carlucci et al. 2021; Schipper, 2023).	en	Mendes, Diego Matheus De Mello, Sobral, Rafael, Neto, Alberto Moreira Da Silva (2023): The Austral Predator Katydid-new species of Megatympanon Piza, 1958 (Orthoptera: Tettigoniidae: Listroscelidinae: Terpandrini) from the Brazilian Atlantic Rainforest.
