Males measure 18–21 mm (0.71–0.83 in) and females 24–30 mm (0.94–1.18 in) in snout–vent length. The coloration is variable; the dorsal ground color is light or dark brown, grayish brown, or orangish brown. Dorsal color patterns include dark chevrons, longitudinal dark lines, and sharply bicolor middorsum from the sides. The ventral surfaces are grayish, sometimes pale grayish yellow. The dorsal skin is finely granular to nearly smooth with scattered warts; ventral skin is areolate. The tympanum is absent. The snout is rounded, sometimes truncate in lateral profile. The upper eyelids have small flat tubercles. The fingers lack webbing but the toes have basal webbing; both fingers and toes have broad discs.[2]
