Description of holotype General aspect robust, bufonoid. Head broader than long; head width approximately 33% of snout-vent length; head lacking cranial crests; snout short, slightly projecting beyond the anterior margin of mouth, rounded in dorsal and lateral views; a prominent, rounded protuberance above snout, extending between the eyes to a point near the mid length of upper eyelid; in lateral view, snout protuberance is raised slightly above the level of upper eyelid; an inconspicuous longitudinal sulcus bisects the snout protuberance; canthus rostralis rounded due to snout protuberance; loreal region slightly concave, vertical; nostrils very small, at tip of snout, directed anteriorly; internarinal distance slightly smaller than upper eyelid width and approximately 60% of interorbital distance; upper eyelid width approximately 70% of interorbital distance; eye diameter greater than internarinal distance, eye to nostril distance, and interorbital distance, and slightly smaller than interorbital distance; tympanum concealed; vocal slits present; tongue rounded, much longer than wide, with posterior margin free; choanae small, rounded, largely separated. Arms slender, lacking ulnar folds; axillary membrane absent. Hand with fingers short; length of fingers from shortest to largest, IVariation The color pattern is highly variable in dorsal and ventral views, primarily in the amount and shape of pale yellow irregular stripes on dorsum, and in the relation of the size of dark brown and pale yellow areas on venter.
