Population Information

It is a very rare species, with few specimens recorded.


Habitat loss is extensive in this area due to agriculture (including corn and rice) and logging for timber. A major suspected threat is either ongoing or future unsustainable exploitation for commercial use as a result of increasing interest in the international pet trade (Ngo et al. 2016).
