Description

Adult males measure and adult females in snout–urostyle length. The snout is short. The tympanum is distinct. The limbs are slender. The

parotoid gland The parotoid gland (alternatively, paratoid gland) is an external skin gland on the back, neck, and shoulder of toads and some frogs and salamanders. It can secrete a number of milky alkaloid substances (depending on the species) known collective ...

s are present as a discrete raised elongated ridge. The fingers and toe tips are rounded. The fingers have traces of webbing while the toes have some basal webbing. Preserved specimens have light brown dorsal ground colour and are conspicuously darker laterally. Most individuals have a fine dark mid-dorsal vertebral line from snout to urostyle. The underside has a slightly translucent pale cream colour. The presence of a small number (18) of large, developed embryos in females suggests that this species is
