A New Genus of Phlugidini (insecta, Orthoptera, Tettigoniidae, Meconematinae) from the Atlantic Forest

In the Neotropical Region, Phlugidini is the most diverse tribe of Meconematinae, with 62 valid species in 10 genera, six of them recorded from Brazil. Brachyphlugis gen. nov. is described herein based on two new species, Brachyphlugis longicercalis sp. nov. (type species) and Brachyphlugis curvata sp. nov., collected in Parque Nacional do Itatiaia and Reserva Biológica do Tinguá, both in the Atlantic Forest of Rio de Janeiro State. The new genus is most similar to Neophlugis, but it can be distinguished from the latter and other neotropical Phlugidini by the following combination of characteristics: (1) mandibles symmetrical; (2) tegmen extending beyond metanotum; (3) pronotal disk posterior margin convex; (4) tenth tergite strongly projected and downcurved; (5) male cercus pronounced with a larger base and acuminate apex; (6) paraproct modified with developed spine; (7) male subgenital plate with two distolateral projections connected to a pair of styles; and (8) female subgenital plate wider than long, posterior margin with two projections. An up-to-date key to neotropical Phlugidini genera is also provided.
