The canthus rostralis is moderately sharp and tympanum is distinct; supratympanic fold is moderately developed. Dorsal skin is rugose with scattered large tubercles. The coloration of the dorsum varies: various shades of brown, yellow-brown, reddish brown, or live-brown are all recorded. Some females show a whitish or pale yellow vertebral line or stripe. Most individuals have a black interorbital line. Some individuals have dark limb bars. The iris is gold or copper-colored.Naming
The specific name "rupinius" is from Latin "rupina", meaning "rocky chasm", in reference to the rocky stream environments this species inhabits.Habitat
Its natural habitats are steep, rocky streams, primarily in premontane wet forests, but also in lowland and lower montane wet forests, between 400 and 2,000 m above sea level. It also occurs secondary forests and shade coffee plantations. While a common species, it is threatened by habitat loss, and potentially, chytridiomycosis.References:
