Madagascar Night Snake (Madagascarophis colubrinus)
Another common name used for this species is the Malagasy Cat-eyed Snake, which is confusing, since that is also the name of its genus, which contains 4 different species. Some even refer to it as the Malagasy Common Snake, even more confusing.

Madgascarophis is a genus of small, mildly venomous colubrid snakes native to the island of Madagascar. They are commonly referred to as Malagasy cat-eyed snakes. Four species are in the genus.
