Abstract

We describe a new dipsadine snake species, of the genus Oxyrhopus Wagler, 1830, from the highlands of Bolivia. Oxyrhopus emberti sp. n. is diagnosed from its congeners based on external and hemipenial morphology. The new species inhabits the humid forests of Yungas and Tucumano-Bolivian Forest highlands, between 1.200 - 1.800 meters above sea level, and is likely to be a Bolivian endemic. We also discuss the relationships of the new species with Andean congeners and provide a key to the identification of the Oxyrhopus species from the Central Andes of Bolivia and Peru.

摘要

我们描述了一种来自玻利维亚高地的新的游蛇科蛇类物种，隶属于1830年瓦格勒所命名的尖吻蛇属。基于外部形态和半阴茎形态，新物种恩氏尖吻蛇（Oxyrhopus emberti sp. n.）得以与同属其他物种区分开来。该新物种栖息于海拔1200 - 1800米之间的永加斯潮湿森林和图库马诺-玻利维亚森林高地，很可能是玻利维亚特有的物种。我们还讨论了该新物种与安第斯同属物种的关系，并提供了一份用于鉴定来自玻利维亚和秘鲁安第斯中部地区尖吻蛇属物种的鉴别指南。
