An alternative common name is Oyacachi jambato toad. Adult males measure and adult females, based on two specimens only, in snout–vent length. The snout is acuminate. The tympanic membrane is absent. The fingers have no webbing whereas the toes are webbed. The dorsum is covered by widely scattered or dense well-defined, rounded warts.

Its upper border fuses laterally with the back of the postglenoid process, while medially it bounds the petrotympanic fissure. The medial part of the lower border is thin and sharp; its lateral part splits to enclose the root of the styloid process, and is therefore named the "vaginal process". The central portion of the tympanic part is thin, as it gives rise to the bony inner two-thirds of the ear canal, and in 5 - 20% of skulls the lower surface is perforated by a hole, the
