The snout is rounded. The eyes are moderately large. The tympanum is indistinct and rather small. The fingers have small discs, those of the toes are slightly larger. No webbing is present. The head and dorsum are uniform dark chocolate brown. The upper flanks are noticeably lighter brown, and the coloration gradually turns to light gray-brown towards the venter.

The iris is dark brown.<ref name="Kraus and Allison 2009"/>
The male advertisement call consists of 6–10 barking notes.<ref name="Kraus and Allison 2009"/>
==Habitat and conservation== The type series was collected from the floor of alluvial wet forest at {{convert|120|m|abbr=on}} above sea level.
