Abstract：
The genus Nanorana contains three subgenera, namely Nanorana, Paa, and Chaparana, and currently, there are four species known to science in Nanorana (Nanorana). In this study, we describe a new species belonging to the subgenus Nanorana from northwestern Yunnan, China. Phylogenetically, the new species, Nanorana laojunshanensissp. nov., is the sister to the clade of N. pleskei and N. ventripunctata. Morphologically, the new species can be distinguished from known congeners by the combination of following characters: present tympanum, equal fingers I and II, small body size, yellow ventral surface of limbs, distinct vomerine teeth, indistinct subarticular tubercles, head width greater than head length, slender supratympanic fold, absent dorsolateral fold, nuptial spines present on fingers I and II in adult males, absent vocal sac, and paired brown spines on the chest. Moreover, we suggest moving the genus Allopaa into Nanorana (Chaparana) and consider that N. arunachalensis is neither an Odorrana species nor a member of the subfamily Dicroglossinae (therefore Nanorana), but probably represents a distinct genus closely related to Ingerana or belongs to Ingerana, pending more data. Additionally, we consider that Nanorana minica deserves the rank of an independent subgenus, and we suggest assigning N. arnoldi, N. blanfordii, N. ercepeae, N. polunini, N. rarica, N. rostandi, N. vicina, N. xuelinensis, and N. zhaoermii into the subgenus Paa and placing N. kangxianensis, N. phrynoides, and N. sichuanensis in the subgenus Chaparana.
摘要：
Nanorana属包含三个亚属，即Nanorana,Paa,还有Chaparana,目前,在Nanorana（Nanorana）中，科学已知有四个物种。在这项研究中,我们描述了一个属于云南西北部Nanorana亚属的新物种，中国。系统发育,新物种,Nanoranalaojunshanensissp。11月。,是N.pleskei和N.ventripunctata进化枝的妹妹。形态学上,新物种可以通过以下特征的组合与已知的同源物区分开来:目前的鼓室，手指I和II相等,身体尺寸小，四肢的黄色腹面，不同的vomerine牙齿，关节下结节，头部宽度大于头部长度，细长的鼓室上褶皱,背外侧褶皱缺失，成年男性手指I和II上存在的新刺，不存在声囊，并在胸部配对棕色的刺。此外，我们建议将Allopaa属移至Nanorana（Chaparana），并认为N.arunachalensis既不是Odorrana物种，也不是Dicroglossinae亚科（因此Nanorana）的成员，但可能代表与Ingerana密切相关或属于Ingerana的独特属，等待更多数据。此外,我们认为Nanoranaminica值得一个独立的亚属，我们建议指派N.Arnoldi,N.blanfordii,大头蛇,波卢尼尼,N.Rarica,N.rostati,N.Vicina,N.xuelinensis,和赵尔米进入Paa亚属，并放置康仙草，N.Phrynoides,和Chaparana亚属的四川N.
