Abstract
Oligodon hamptoni is a rare species of Kukri Snake known from only two specimens, both collected nearly a century ago in northern Myanmar. Here, we report the third record of this species based on a photograph taken in Mt. Gaoligongshan, Tengchong City, Yunnan Province, China, approximately 235 km northeast of the nearest record in Bhamo District, Kachin State, Myanmar. We also provide a detailed redescription of the holotype, showing that the photo record from Mt. Gaoligongshan can be unambiguously identified to this species. This rediscovery represents the first observation of O. hamptoni in China and is the first report of this species in almost 100 years.
