Checklist of Gripopterygidae (Insecta : Plecoptera) and a new species, Tupiperla nessimiani, from Reserva Biológica de Araras, Rio de Janeiro State, Brazil

Gripopterygidae comprises about 60 species in Brazil, most of which inhabit mountainous streams along the Atlantic coast. The genus Tupiperla includes 26 species, mainly occurring in mountainous streams of the Atlantic Forest. We present a checklist of Gripopterygidae from the Araras Biological Reserve (REBIO Araras), Rio de Janeiro State, Brazil. We documented 15 species representing four genera. Three species are reported from Rio de Janeiro for the first time: Paragripopteryx blanda, P. delicata and P. intervalensis. Additionally, a new species, Tupiperla nessimiani, is described and illustrated based on male specimens collected in REBIO Araras. Tupiperla nessimiani is distinguished by the narrow extension of tergum 10 with divergent margins and a shallow apical incision, and by the elongate, rod-like paraprocts, bearing a dark, thorn-like subapical spine. This study contributes to reducing Linnean and Wallacean shortfalls in Brazilian Gripopterygidae.
