New records of the red-rumped mouse Juliomys pictipes (Osgood, 1933) (Rodentia: Sigmodontinae) in coastal Atlantic forest of Paraná, southern Brazil

Juliomys pictipes is an Atlantic Forest endemic Sigmodontinae rodent. Herein we report the first records of the species in the coast of the state of Paraná, filling a gap in the species distribution. Records at low altitudes at the eastern part of the Serra do Mar confirms that the coastal mountains are not a barrier to the species distribution.
