Distribution
editThis 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
editNyctixalus 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
editNyctixalus 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]
