Male Tonkin frogs measure 36–55 mm (1.4–2.2 in) (based on just two specimens) and females 78–105 mm (3.1–4.1 in) in snout–vent length. Skin on the dorsum is shagreened with heavy granulations. The dorsum, flanks, and loreal region are brown with small black spots that get larger on the flanks. The upper and lower lips are creamy yellow with vertical black bars. The venter is creamy white, sometimes with light spotting. The iris is golden, and the margin of pupil has a striking yellow and red border.
