Identification. This large treefrog has a uniform brown dorsum. The iris is plain brown without reticulations. The tympanum is about ¼ the length of the head and males have abundant keratinized tubercles covering the dorsum.

Habitat. This species occurs in both primary and secondary forests and has also been recorded in disturbed areas near buildings.

Remarks. Newly metamorphosed Osteocephalus verruciger from WWS have orange and yellow mottling on the limbs which is not present in other populations of this species; however, the adults exhibit the typical color for the species ( Ron et al. 2010).
