First survey of the Passalidae (Coleoptera, Scarabaeoidea) species from Reserva Ecológica de Guapiaçu (REGUA), Cachoeiras de Macacu, RJ, Brazil

We present the details of a survey with species of passalid conducted in the Reserva Ecológica de Guapiaçu (Cachoeiras de Macacu, Rio de Janeiro State) together with illustrations for each species and an identification key. The study includes material collected between May 2010 and October 2013. We identified 11 species in three genera and two tribes (Passalini and Proculini). Passalini comprised two genera, Passalus with six species, and Spasalus with one species, representing 71.42% of all the species encountered. Proculini was represented by only one genus Veturius, with four species, representing 28.57% of the species surveyed. Nine species were recorded for the first time from Cachoeiras de Macacu municipality
