Brown-speckled whipsnake or brown vine snake (Ahaetulla pulverulenta) is a species of tree snake endemic to Sri Lanka.[3] Populations in the Western Ghats of India are now considered a separate species, Ahaetulla sahyadrensis.[4] It is known as හෙනකදයා (henakadaya) in Sinhala; this name provided the name anaconda.[5][6][7]
