The Black-winged Spiny Katydid-new species of Pemba Walker, 1870 (Orthoptera: Tettigoniidae: Pseudophyllinae: Teleutiini) from the Brazilian Floodplain Paleo-Várzea Forest

Pemba Walker, 1870 (Pseudophyllinae: Tettigoniidae) is a genus of large katydids characterized by a dark brown coloration, endemic to the Amazon region. It currently includes four species: Pemba armata Walker, 1870 (type species); Pemba brunnea Beier, 1960; Pemba cochleata Beier, 1960; and Pemba peruana Beier, 1960. The group has a distribution restricted to the northwestern Amazon biome, in Ecuador and Colombia.

In this study, a new species, Pemba paleovarzeana sp. nov., from the municipality of Maraã, Amazonas, is described, representing the first record of the genus in Brazil. Additionally, a dichotomous key to the species of the genus is provided, along with male calling song data, natural history information, a map, and comments on its distribution in the Brazilian Amazon.
