José Daniel Ramírez-Fernández, Jim Córdoba-Alfaro, Diego Salas-Solano, Francisco J. Durán A., Bernal Rodríguez-Herrera


The Rufous Tree Rat, Diplomys labilis, is known to range geographically from Central Panamá to Colombia and probably Ecuador. It occurs in a variety of habitat types where it moves by the branches in the high canopy at night. We report the Rufous Tree Rat for Costa Rica, ranging outside its geographical distribution about 490 km west from its type locality.
