A new species of the endemic Himalayan genus Liurana (Anura, Ceratobatrachidae) from southeastern Tibet, China, with comments on the distribution, reproductive biology, and conservation of the genus

  • 摘要: 依据DNA分子及形态数据,依据西藏墨脱县标本描述舌突蛙属Liurana一新种。该新种具备以下形态鉴别特征,区别于同属近缘种:1)头宽大于头长;2)鼓膜较大且裸露;3)后肢较长,后肢贴体前伸时,胫跗关节超过吻端;4)腹部具扁平疣粒,泄殖腔附近具细小颗粒;5)四肢背面具数条明显横纹,其中大腿4条,小腿3条;6)腹部白色,具深棕色云纹或大块斑点。同时,本研究讨论了舌突蛙属在东喜马拉雅地区的分布格局、雅鲁藏布江在该属物种形成及基因隔离上所起的作用、该属直接发育的特殊繁殖方式以及该属物种的两种生态型。最后,依据调查研究结果,对该属物种在西藏的保护提供了意见。

     

    Abstract: A new species of the genus Liurana Dubois, 1986 is described from Medog County, Tibet, China, based on morphological and molecular data. The new species can be differentiated from all other congeners by the following combination of characters: (1) head wider than long; (2) tympanum distinct and large; (3) hindlimb long, tibiotarsal articulation beyond tip of snout when adpressed; (4) belly with flat tubercles, cloacal region with small tubercles; (5) transverse bands distinctly on dorsal limbs, four bands on thigh and three on tibia; and, (6) dark brown marbled patterns or speckles on white belly. Here, we also discuss the distribution pattern of Liurana in the East Himalaya region, the role of the Yarlung Tsangpo River in the speciation and genetic isolation of congeners, the direct developmental mode of reproduction, and the two different ecotypes of the genus. Lastly, we provide conservation recommendations for the genus in southeastern Tibet.
