Adelophryne gutturosa (common name: Guiana Shield frog) is a species of frogs in the family Eleutherodactylidae.[2] It is found on the Guiana Shield from eastern Venezuela through Guyana[3] to French Guiana and adjacent Brazil (Amapá), possibly extending to Suriname. Its type locality is Mount Roraima.[2][4] Its local Spanish name is ranita guturosa.[1]
Taxonomy
Recent molecular research suggests that A. gutturosa consists of more than one species.[5]
Description
Adult males measure 12.4–14.7 mm (0.49–0.58 in) and females 12.6–16 mm (0.50–0.63 in) in snout–vent length.[6][3][7] The snout is truncate. The head is slightly wider than the body. The tympanum is small but distinct. The canthus rostralis is indistinct. Females have a horizontal supra-tympanic fold. The fingers have asymmetrically pointed tips but no discs, whereas the toe tips have grooved, asymmetrically pointed discs. Skin is smooth.[6] The dorsum is light brown and flanks are black.[7] Males have large subgular vocal sac.[6]
Habitat and conservation
Adelophryne gutturosa occurs in the leaf-litter on the forest floor of rainforests near streams at elevations of 40–2,200 m (130–7,220 ft) above sea level. Males call from the base of plants (often formations of Monotagma spicatum), hidden among rootlets and dead leaves.[1]
This species is not common, although its secretive habits also make it difficult to find. No significant threats to it have been identified, and its range includes several national parks.[1]
