Choerophryne darlingtoni grows to a maximum snout–vent length of 27 mm (1.1 in). The snout is blunt, similar in length to the eye. The fifth toe is longer than the third.[4] Coloration is highly variable. A thin vertebral line or a broad light vertebral stripe may be present. The dorsal ground color varies from deep plumbeous to pale yellowish tan. Various darker markings are present. A pale, golden interocular line is almost always present but is sometimes indistinct. The venter is pale and nearly immaculate to grey.[5]
Its natural habitats are montane forests[1] at elevations above 2,000 m (6,600 ft).[2] It is a locally abundant species but can be locally threatened by habitat loss caused by selective logging and forest clearance.[1]
