In an adult male the SVL measured to be 23.4 millimeters. SVL in adult females ranges from 26 to 37.4 millimeters. Cranial crest are well-developed above small eyes that contain a horizontally elliptical pupil. Head is more broad than long. The skin on the surface of the upper head is co-ossified to the skull. The parotoid glands are smooth egg shapes that are marginally smaller than area of the upper eyelid. There are no vocal slits or sacs. There are pointed warts on the upper surface of the thighs. On both hands and feet the first digit is shortened and surrounded by an extensive amount of webbing that forms ample padding. Finger I is shorter than finger II. In adult males finger I has a light-colored nuptial pad. Webbing is also extensively present on the toes, where toe I and II have no distinction from one another.

General color present on upper surfaces is gray to orange. A dark lateral stripe runs down from the parotroid to the groin. Occasionally a specimen will have an orange mark posterior to the parotoid glands. Ventor is light brown with bluish complexion.
