中文摘要:
      安徽树蛙(Zhangixalus zhoukaiyae)与丽水树蛙(Z. lishuiensis)自发表以来一直存在分类争议。为进一步探讨这两个物种的分类问题,本研究在浙江省和安徽省交界处(浙江淳安-安徽黄山)开展了长期的野外监测,采集到张树蛙属标本5号,并将该5号标本与安徽树蛙及丽水树蛙模式产地标本进行形态学比较和系统发育分析。结果表明,上述5号标本形态差异小,与安徽树蛙及丽水树蛙模式标本进行比较后,未发现显著形态学差异。基于16S rRNA基因的系统发育分析表明,本研究样本与安徽树蛙和丽水树蛙模式标本序列聚成一单系支;本研究样本与安徽树蛙模式标本遗传距离1.3%,与丽水树蛙模式标本遗传距离0.8%。基于本研究的分析结果,进一步厘清了丽水树蛙和安徽树蛙的分类争议,丽水树蛙可能是安徽树蛙的同物异名,它们应为不同的地理种群,彼此之间尚未达到种间差异水平。
英文摘要:
      [Objectives] The long-standing issue of classification controversy between Zhangixalus zhoukaiyae and Z. lishuiensis has existed since their first publication. To further explore and resolve this controversy, an extensive field monitoring study was conducted at the border of Zhejiang and Anhui Provinces, specifically (Huangshan, Anhui and Chun’an, Zhejiang). Five specimens of the Zhangixalus genus were collected. Morphological comparisons and phylogenetic analysis were performed on these five specimens alongside specimens of Z. zhoukaiyae and Z. lishuiensis obtainedfrom their respective type localities. [Methods] Morphological characteristics of the five specimens including 12 morphological data indicators were measured by a vernier caliper, and analyzed together with the holotype of Z. zhoukaiyae and Z. lishuiensis (Table 2). The 16S rRNA gene fragments were amplified for these five specimens, combined with NCBI GenBank data (Table 1), a Bayesian tree was constructed using Mrbayes 3.1.2 and p-distance model in MEGA 6 was used to calculate the genetic distance between individuals of Zhangixalus. [Results] Our results show no significant morphological differences between the five specimens and the type specimens of Z. zhoukaiyae and Z. lishuiensis. Based on the phylogenetic analysis of the 16S rRNA gene, the five samples clustered into a monophyletic group with the sequences of the type specimen of Z. zhoukaiyae and Z. lishuiensis (Fig. 2). The genetic distance between our five samples and the type specimen of Z. zhoukaiyae is 1.3%, and that of the type specimen of Z. lishuiensis is 0.8%. The genetic distance between the type specimens of Z. zhoukaiyae and Z. lishuiensis is 1.6% (Appendix 1). [Conclusion] Our analysis inferred that Z. lishuiensis is a synonym of Z. zhoukaiyae, our results resolved the existing classification controversy between them. We therefore recommend that Z. lishuiensis and Z. zhoukaiyae should be treated as different geographical populations, as they have not reached the level of interspecific divergence.
