Ahaetulla, commonly referred to as Asian vine snakes or Asian whip snakes, is a genus of colubrid snakes distributed throughout tropical Asia. 

The genus name Ahaetulla comes from the Sri Lankan Sinhalese words ahaetulla/ahata gulla/as gulla, meaning “eye plucker” or “eye picker”, because of the belief that they pluck out the eyes of humans.

Asian vine snake, or Oriental whipsnake (Ahaetulla prasina) is an arboreal, moderately venomous species of opisthoglyphous vine snake in the family Colubridae, found in Southern and Southeast Asia.

Colubridae (/kəˈluːbrɪdiː/, commonly known as colubrids /ˈkɒljʊbrɪdz/, from Latin: coluber, 'snake') is a family of snakes.

Elaphe is a genus of snakes in the family Colubridae. Elaphe is one of the main genera of the rat snakes, which are found in many regions of the northern hemisphere.

Elaphe moellendorffi, commonly called the flower snake or Moellendorf's rat snake, is a species of snake in the family Colubridae. 

Rhabdophis is a genus of snakes in the subfamily Natricinae of the family Colubridae. Species in the genus Rhabdophis are generally called keelback snakes, and are found primarily in Southeast Asia.

The name Rhabdophis comes from the Greek words rhabdos (meaning "rod" or "wand") and ophis (meaning "snake"), referring to the snake's appearance or structure. 
Together, Rhabdophis literally means "rod snake" or "wand snake," which likely describes a particular anatomical feature or the overall slender form of the snakes in this genus.
