[4][5] Following the description of this species, specimens labelled as Rana doriae andamanensis collected by Nelson Annandale were found from the Zoological Survey of India.

The tympanum is distinct and exposed; the supra-tympanic fold is well-developed and forms a thick, fleshy ridge.

The finger and toe tips bear swollen discs, without circum-marginal grooves.

Colouration is variable with three different morphs: Minervarya charlesdarwini have been found in primary evergreen and secondary forests at elevations below 500 m (1,600 ft).
