Golden-capped boulder frog

The specific epithet pakayakulangun has the approximate meaning of ‘belonging among the boulders’, from a local term in Kuuku Ya’u, a language of the Pakadji, or Sandbeach People, of eastern Cape York.[1]

The species grows up to about 55 mm in length (SVL). Colouration is grey or brown on the back; the belly is pale grey; there is often a yellow patch over the snout and eyelids. There are dark stripes from the snout to behind the eyes; the groin and backs of the thighs are pale orange-pink. The fingers and toes are unwebbed.[2]

The frogs feed primarily on ants.[1]

The species is only known from the type locality, just south of Stanley Hill and north of the Pascoe River, on the Cape York Peninsula of tropical Far North Queensland.[2] There the frogs inhabit deeply piled granite boulder fields festooned with tropical rainforest vegetation.[1]
