Adelophryne patamona

Adelophryne patamona is a species of frogs in the family Eleutherodactylidae. It is endemic to the Pacaraima Mountains of southwestern Guyana,[3][4] although it is likely to also occur in the adjacent Roraima state, Brazil.[1][3] It is most closely related to A. gutturosa.[5]

Description

Adult males measure 17–18 mm (0.67–0.71 in) (based on just two individuals) and adult females 21–23 mm (0.83–0.91 in) in snout–vent length—it is the largest species of its genus. The snout is rounded. The tympanum is small and covered by a fold posterodorsally. Skin of dorsum, venter, and limbs is smooth but has scattered small tubercles. The flanks and rear of thighs are areolate. The fingers are flattened, unwebbed, and have small pointed discs at their tips. The toes are also flattened, unwebbed, and have small narrow discs at their tips. Colouration is variable; the ground colour of dorsum, flanks and dorsal surfaces of limbs is medium brown, and there are black marking. Some specimens are darker and have more pale blue spots and more conspicuous tubercles on dorsum.[2]

The male advertisement call is a group of three soft, unpulsed, whistle-like notes. The first two are short and third longer one long, all produced in rapid succession.[2]

Habitat and conservation

Adelophryne patamona is known from medium-cover forests at elevations of 678–1,414 m (2,224–4,639 ft) above sea level (the highest of all Adelophryne species[2]). Specimens have been found amidst leaf litter, among rootlets near the base of trees, and in ground holes covered by leaves. Males call in the afternoon and night, mostly from concealed sites.[1][2]

This species is locally common. No threats to it are known, and it occurs in an area with sparse human population.[1]
