Description: Atelopus patazensis has a robust body. The SVL of males is 37.8-39.8 mm and of females is 42.7-48.8 mm. The head length is about equal to the head width. A. patazensis has neither tympanic membrane nor tympanic annulus. The snout is truncated when viewed from the dorsal side and extends past the lower jaw. The forearms are short. The fingers have rounded pads and lack a circum-marginal groove. Relative length of fingers in increasing order are as follows: I,II,IV,III. The front foot is not webbed but the hind foot is webbed. The body’s dorsal surface on both males and females has warts. Females have pointed projections in the skin present in the postorbital area, dorsolaterally, and on the sides. Males have a row of large warts dorsolaterally and spiculae posteriorly on the throat and under the jaw (Venegas et al. 2008).
Coloration: Colors vary dorsally from almost entirely black with orange patterning to almost entirely orange with black patterning. The pupil is black and fully encircled by a ring of dark gold. Preserved specimens lose their orange color and appear yellow. Colors vary dorsally from almost entirely black with orange patterning to almost entirely orange with black patterning (Venegas et al. 2008).
Tadpole Morphology: A. patazensis belongs to the family Bufonidae, all of which have type IV tadpole morphology (Venegas et al. 2008).
