The only precisely known record is from the eastern slopes of the Andes in the Amboró National Park, in the Santa Cruz Department.
Preserved specimens have dull grayish brown (tan) dorsal coloration with dark brown markings consisting of small, irregular spots (the female) or larger spots (the male).
The venter is creamy white with dark brown flecks along lip margins and laterally on the chest and belly.
The other specimen was collected in a cloud forest at an elevation of 2,286 m (7,500 ft) above sea level in 1996.
Management of the Amboró National Park to ensure survival of this species is crucial.
