Abstract

We present data on a new record of Toromys grandis, a species not sampled for almost 60 years. The species is known from the newly-collected specimen and 206 specimens housed in museums worldwide. The gut morphology, consisting of very long intestines and well-developed caecum, suggest that T. grandis is a potential herbivore also adapted to omnivory. Our record at the Reserva de Desenvolvimento Sustentável (RDS) Piagaçu-Purus extends the range of T. grandis approximately 150 km southwestward and represents the second record of the species within a protected area.

Acknowledgments

We are grateful for the financial support provided by the American Society of Mammalogists through the Latin American Student Field Research Award and by the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) through the PhD fellowship, both to E.F. Abreu-Júnior; to Cristiano Neves de Oliveira and Maria do Carmo for logistical and bureaucratic support at RDS Piagaçu-Purus; to people who hosted us and helped us during the field work: Padre, Noca, Barbozinha and Bengala; to our field work assistants: Faris, Berge, Prefeito, and Bengala; to Eduardo Von Mühlen and Heloisa Brum to introducing the region to us and for the logistical support in the field; to Jeronymo Dalapicolla and Ana Carolina Pavan for checking specimens housed at the MPEG and AMNH, respectively. We are also thankful to Gilson E. Iack Ximenes for sharing with us valuable information on this species and to Louise H. Emmons for critically reviewing the manuscript and providing important suggestions, both on the English language and scientific contents.
