A new species of bufonid frog of the genus Ansonia is described from Sabah, northern Borneo. The new species is distinguished from others in the genus by absence of a tympanum. The tadpole assigned to this species is also distinguished from other known larvae of Ansonia by its possession of a distinct abdominal sucker behind the oral disc and by the absence of an upper jaw sheath. This species is the twelfth Ansonia known from Borneo.
