Ansonia mcgregori

Adult males measure 32–39 mm (1.3–1.5 in) and adult females 43–50 mm (1.7–2.0 in) in snout–vent length. The tympanum is not visible. All the finger tips are rounded and have small discs, not wider than rest of the phalanges. The toes are almost fully webbed. The hind legs have crossbars. The adult males have a subgular vocal sac.[4]

Ansonia mcgregori is a terrestrial toad associated with cool mountain streams and rivers in lower montane and lowland forests at elevations of 300–1,700 m (980–5,580 ft) above sea level. Individuals have been found above rocks covered with mosses, on rock crevices, and on leaf litter near streams. Although it is generally restricted to undisturbed or minimally disturbed habitats, a few individuals have been found in secondary forest, plantations, small-scale agroecosystems, and in the floor of a cave surrounded by farmland–disturbed lowland dipterocarp forest mosaic. Breeding takes place in streams.[1]

This species is common in suitable habitat. It is threatened by habitat loss caused by small-scale agricultural activities, large-scale oil palm plantations, wood collection for charcoal production, and expanding human settlements. Furthermore, agricultural effluents, soil erosion, and mine tailings can impact its stream habitat. It is known to occur in several protected areas.[1]
