Description

Adult males measure and females in snout–vent length. The body is sturdy with muscular arms and legs (these frogs are powerful jumpers). The toes are partially webbed and thinner than the fingers which are short, thick, and unwebbed. The head is wider than long, with a broad, rounded snout. The eyes are large, and tympanum is visible but not large. The back is reddish brown with some whitish granulations. The hind legs have transverse, darker bands. The throat is pinkish yellow, and the stomach is pale. Skin is dorsally quite granular or warty. Also ventral region is also very granular, apart from the throat that is fairly smooth.


Habitat and conservation

''Insuetophrynus acarpicus'' inhabits coastal streams in temperate forest. Adults hide under stones during the day, emerging at night to feed along the stream margins. Tadpoles can be found under stones in muddy areas with slow current. The species has a small area of distribution (its known range extends only 33 km along the coast) and its habitat is threatened by clear cutting and afforestation.
