Aphantophryne sabini

Males can grow to 17 mm (0.7 in) and females to 24 mm (0.9 in) in snout–vent length. The overall appearance is squat, and the head is notably narrower than the rotund body. The snout is rounded. The tympanum is poorly visible. The fingers and toes have rounded tips and no webbing. The hind legs are short. The holotype has orange-tan dorsal ground color, dark brown dorsal markings, and a white vertebral stripe bordered with black. However, most specimens lack the vertebral stripe. The darker dorsal pattern ranges from reddish brown to dark gray-brown. The flanks range from yellowish tan through duller tan to orange; the abdomen has a paler shade of orange^[2]

Aphantophryne sabini is similar to Aphantophryne pansa but slightly smaller. The most distinctive feature is the male advertisement call, which is a prolonged series of soft "clicks" in A. sabini; that of A. pansa is shorter but uttered at a higher click rate.^[2]

Aphantophryne sabini is known from montane grassy meadows, montane forest edges, and treefern-dominated grasslands at elevations of 2,080–2,600 m (6,820–8,530 ft) above sea level.^[1][2] Breeding is presumably by direct development (i.e., there is no free-living larval stage). It is a common species. There are no known threats to this species because habitats in the area where it occurs are probably reasonably secure.^[1]
