Nyctixalus pictus, also known as cinnamon frog, cinnamon treefrog, cinnamon bush frog, painted Indonesian treefrog, and white-spotted treefrog, etc., is a species of frog in the family Rhacophoridae. [1] [2] [3] [4] It is found in the Malay Peninsula (including southernmost Thailand), the Philippines, and parts of the Greater Sunda Islands (northern Borneo and northern Sumatra). [1] [2]

Distribution

This species is found in the Malay Peninsula (from extreme southern Thailand through Peninsular Malaysia to Singapore), Sumatra (Indonesia), Borneo (Brunei, Malaysia, and Indonesia), and the Philippines. [1] [2]

Description

Nyctixalus pictus grows to about 35 mm (1.4 in) in snout–vent length; [3] [4] males are slightly smaller than females. The snout is pointed. The tympanum is distinct. [5] The limbs are long and the finger and toe tips are dilated into large discs. [4] [5] The fingers have no webbing whereas the toes are partly webbed. [5] Coloration is brown or reddish brown with white to yellow spots on the body. [4]

Habitat and conservation

Nyctixalus pictus occurs in the shrub and lower tree layers of primary and secondary forests at elevations below 700 m (2,300 ft) [1] (up to 1,650 m (5,410 ft) in Borneo [3] ). The tadpoles develop in arboreal water-filled cavities (including phytotelms) and in rotting logs. [1] [3]

Nyctixalus pictus is widespread but uncommon. Populations are threatened by habitat loss due to clearing of forests for agriculture and logging. Its range includes several protected areas. [1] In Singapore, it is only found in the Bukit Timah and Central Catchment Nature Reserves. [4]
