Liophidium pattoni is a species of snake in the subfamily Pseudoxyrhophiinae of the family Pseudoxyrhophiidae.

Little is known about the snake as it was recently described in 2010, although its existence had been known for some decades (one was pictured in a 1996 guidebook[3]) before a specimen could be caught for detailed study.

[5] L. pattoni can easily be distinguished from other members of the genus Liophidium by its unique color pattern.

It is a thin-bodied snake with a black dorsum with discontinuous pink stripes that fade to blue-gray and white towards the posterior.

[5] L. pattoni is a terrestrial hunter, and while its diet is largely unknown, the holotype was collected with a Malagasy ground skink (Madascincus melanopleura) in its stomach, suggesting that it feeds on small terrestrial rainforest fauna.
