[3][4] The specific name cavernibardus is derived from the Latin caverna for "cave" and bardus for "singer".

Dorsal coloration is variable but usually including green, and usually with a dark, vague X-like pattern.

[2] The species' natural habitats are montane forests[1] at elevations of 930–1,200 m (3,050–3,940 ft) above sea level.

[4] Individuals have been found in small caves under granite boulders, in the roots of aroids on the tops of boulders, perched on leaves some 1 metre above the ground,[1] and on the ground in forest bordering a river.

[4] Based on calling males, it seems to be one of the most common frogs in its type locality.
