Dendrelaphis caudolineolatus, commonly known as Gunther's bronzeback tree snake, is a species of snake of the family Colubridae.
It was described and named, as Dendrophis caudolineolata, by Albert Günther of the British Museum in 1869.[1]
The snake is found in Sri Lanka, where the type specimen, now in the Natural History Museum, London, was collected by Richard Hawksworth Barnes.
