Geographic Range [top]

Range Description:This poorly-known species occurs in Ecuador and Peru east of the Andes (Woods and Kilpatrick, 2005). The type locality is Gualea, at 1,300 m, Mount Pichincha, in the western slopes of the Andes, but this seems erroneous since all others known records are from the lowlands of the eastern side (Emmons and Feer, 1997).
