Myanmar, a biodiversity hotspot, harbors a striking diversity and endemism of species. Despite this, its herpetofauna remains one of the least explored in continental Asia due to restrictions of crossing political boundaries and infrastructure in remote regions. Many species in adjacent China and India are hypothesized to occur in Myanmar but records are wanting. Recent fieldwork found the frogs Polypedates braueri, Nasutixalus jerdonii and Oreolalax jingdongensis there, and the latter two species represent new generic records for Myanmar. All major morphological characters of these populations match the original descriptions. In addition, our matrilineal genealogy based on DNA barcoding confirms their identities. Overall, these findings confirm that the amphibian diversity is underestimated and this has important implications for conservation. Analyses indicate that northern Myanmar is a biogeographic corridor for the Himalayas, southern China, and northeastern India.
缅甸是一个生物多样性热点地区,拥有显著的物种多样性和特有性。尽管如此,由于跨越政治边界的限制以及偏远地区基础设施的匮乏,其爬行动物区系仍然是亚洲大陆探索最少的地区之一。据推测,相邻的中国和印度的许多物种在缅甸也有分布,但相关记录却很少。最近的野外调查在那里发现了布氏泛树蛙、杰氏鼻蛙和景东齿蟾,后两个物种代表了缅甸新的属记录。这些种群的所有主要形态特征都与原始描述相符。此外,我们基于DNA条形码的母系谱系确认了它们的身份。总体而言,这些发现证实了两栖动物的多样性被低估了,这对保护工作具有重要意义。分析表明,缅甸北部是喜马拉雅山脉、中国南部和印度东北部的生物地理走廊。
