根据2条雌性标本描述了产于中国西南部的亚洲绿色蝰蛇一新属新种。一个新的DNA同源性恢复的两个标本的新物种作为一个支持良好的分支，是姐妹组的所有采样的代表属Viridovipera和Cryptelytrops。新属与其他pitviper属的区别在于形态特征的组合，包括没有侧条纹，大型身体尺寸，以及成年雌性的深红色眼睛。在形态上，新物种在身体尺寸和比例上与Popeia物种表面上最相似，但在遗传上非常不同。该新属/种目前仅见于四川南部海拔约1000 m的万年青雨林中。
A new genus and species of Asian green pitviper is described from Southwest China based on two female specimens. A new DNA phylogeny recovers the two specimens of the new species as a well-supported clade that is sister group to all sampled representatives of the genera Viridovipera and Cryptelytrops. The new genus is distinguished from other pitviper genera by a combination of morphological characters, including the absence of a lateral stripe, large body size, and deep red eye in adult females. Morphologically the new species is superficially most similar to species of Popeia in body dimension and scalation, but is genetically extremely distinct. The new genus/species is currently known only from south Sichuan, where it was found at about 1000 m above sea level in less disturbed evergreen rainforest.
