Newly discovered: Trimeresurus cyanolabris, the blue-lipped green viper

A newly identified species of venomous snake, Trimeresurus cyanolabris, has been discovered in the dry tropical forests of central Vietnam. This multicoloured snake has a bright grass-green body, yellow eyes, brick red tail, and blue lips, chin, and throat, earning it the nickname blue-lipped green pitviper.

T. cyanolabris is most active at dusk and after nightfall, feeding on small frogs and lizards. During the day, it can be found perched on branches or in tree hollows near streams. This species is one of 50 closely related Asian snakes and can be distinguished by its unique colors and smaller size.

Researchers at Lomonosov Moscow State University in Russia, led by Sabira Idiiatullina, confirmed the distinctiveness of T. cyanolabris using genetic analysis. They also discovered that its closest known relative is the red-eyed T. rubeus. Genetic methods are expected to identify more Trimeresurus species in the future, as this group of venomous snakes is known to be highly diverse.

Unfortunately, the habitats of many Trimeresurus species are at risk of deforestation, threatening their survival. More research and conservation efforts are needed to protect these unique and fascinating snakes and their ecosystems.
