Coelognathus radiatus
Range
Bangladesh, north-east India, southern China and Southeast Asia
The radiated rat snake, also called the copperhead rat snake or copper-headed trinket snake, is a non-venomous colubrid. These snakes are usually defensive in nature, which makes them hard to catch or control. The account opened lists local names in Bengali and Vietnamese and gives its range as Indonesia, Malaysia and Brunei, north-east India (Assam, Arunachal Pradesh) and southern China (Wikipedia, general species account).
That range list, as shown, does not include Nepal and the Reptile Database summary starts with Indonesia, so the Nepal record is flagged for checking. No size, colour, habitat, diet or breeding information was found in the sources opened, so none is stated.
