Description of holotype Head short, wide and very depressed. Loreal region sloping and concave. Snout 'ery short, not projecting (hardly visible from the ventral side), but prominent. Rostrum nearly vertical. Nostrils elongate and oblique. Cephalic crests well developed, with smooth or somewhat rippled borders. Canthal crests with smooth borders. Subnasal crests distinct. Suborbital crests well separated from the lower border of the eye, fonning a small projecting arch, expanded laterally and prolonged beyond postorbitals. Preorbital crests marked. Postorbital crests marked and somewhat separated from the tympanum. Maxillary crests very much expanded laterally; seen from above, the maxillaries project laterally; ventrally, the maxillaries appear as an expanded rim. Supraorbital crests projecting, with short divergent crests in the parietal region; interorbital space concave and veiy wide, granular and with short divergent crests on the canthal apex. Parietal crests marked. Orbitotympanic crests with thick border. Tympanum visible, gently sloping. Parotoids not prominent, length 7 mm; dorsally with flat granules. Granules on the dorsum rather smooth. The row of granules on the inner tarsal edge indistinct. A vertebral light line, thin and irregular; dorsal coloration generally dark gray or brown, with scattered, small darker spots. Belly with dark spots. Measurements of holotype ( in mm ) . Head and body 50. Head length 11. Head width 15.5. Head height 5. Eye 3.5. Interorbital space 7. Upper eyelid width 3. Elbow to third finger 17. Femur 14. Tibia length 14. Tibia width 5.

Vertebral light line generally absent or only indicated. Ventrally sometimes without spots.
