Description

Adult males measure 22–24 mm (0.9–0.9 in) and adult females, based on just one specimen, 26 mm (1.0 in) in snout–vent length. The snout is pointed in dorsal view and acuminate in lateral view; in males, the snout tip has a well-developed, shovel-like fleshy ridge. The tympanum and supratympanic fold are present. The finger tips are rounded but not expanded, without webbing or fringing. The toe tips are unexpanded and unflattened; no webbing is present. Dorsal coloration consists of 4–6 symmetrically arranged rows of longitudinal dark-colored spots on moss green (male) or grayish brown (female) background. Cream-colored vertebral stripe is present. The belly is uniformly yellow. Males have an internal, subgular vocal sac.^[3]

The male advertisement call is long (63–151 ms) with 15–21 pulses; it is audibly pulsed even to the human ear.^[3]
