Conraua beccarii (Boulenger, 1911)
This species was originally described as Rana beccarii (Boulenger 1911).
This species is very large and, while it is not exclusively aquatic, it tends to stay very close to rivers, streams, and occasionally the large pools associated with them. Its most distinctive feature is its large head, the width of which commonly exceeds half of the snout-vent length, and which is marked with two prominent muscular bumps, one on either side, separated by a distinct groove. Adult coloration is very dark with indistinct mottling that may include hues of black, purple, or brown; the underside of the frog is lighter but may be heavily mottled with gray or brown, especially anteriorly and laterally. Juveniles may be lighter dorsally and have distinct dark crossbars on the limbs. The tympanum is not visible externally, and the toes are fully webbed with distinct terminal discs (Boulenger 1911, Scortecci 1931, Spanò 1971, Largen and Spawls 2010).
