Wall's bronzeback

Dendrelaphis cyanochloris

(Frank Wall, 1921)

In Thai: งูสายม่านฟ้าเขียว (ngu sai man fa khieow)

Dendrelaphis cyanochloris, commonly known as Wall's bronzeback or the blue bronzeback, is a species of snake found in Southeast Asia.


The species occurs in India (Assam, Arunachal Pradesh (Namdapha - Changlang district); Andaman Islands, northern parts of West Bengal), Bangladesh, Myanmar, southern Thailand, and western Malaysia (Pulau Pinang, Pahang, Pulau Tioman), possibly also in Bhutan. It is predominantly arboreal and inhabits primary and mature secondary lowland rainforest, at altitudes of up to 1, 000 m.


Like other bronzebacks, this snake is diurnal and fully arboreal.


Common and widespread, Wall's bronzeback is currently classified as Least Concern by the IUCN, although it is likely impacted by localized habitat loss and degradation from agricultural expansion and logging.
