Snout-vent lengths for females are between 27.3 and 37.2 mm and for males are between 25.1 and 30.8 mm. The ventrum has a brown background with smooth edged, white spots generally separated from each other by at least their shortest diameter. There is no dark inguinal spot. The ventral and dorsal colorations are separated by a broad, dark brown, lateral band which passes from the tip of the snout, above the nostril, through the middle of the eyes and above the shoulder, to the groin and anterior face of the thigh. It is bordered dorsally by an indistinct light stripe above which the brown dorsal coloration is lighter than that of the venter. The dorsum has a faint, darker brown, irregular inverted V or is unmarked. The thighs each have two parallel dark bands. The hind foot has a single metatarsal tubercle, rudimentary webs which extend roughly to the proximal joint of the fourth toe, and tips of the outer toes which are flattened dorsoventrally and slightly dilated laterally. Males have a dark throat, larger webs, and pustules on the chin, and females have perianal pustules.
