在前往曼德勒的道路上:对缅甸姬蛙属(两栖类:无尾目:姬蛙科)物种区系进行厘定并描述2个新种

On the road to Mandalay: contribution to the Microhyla Tschudi, 1838 (Amphibia: Anura: Microhylidae) fauna of Myanmar with description of two new species

  • 摘要: 我们根据对缅甸中部(马圭)和北部(克钦邦)姬蛙属(Microhyla)样本的收集情况,使用分子和形态学方法对缅甸的姬蛙属多样性进行了评估。本研究总共发现姬蛙属6个物种,分别是缅甸姬蛙(M. berdmorei)、小弧斑姬蛙(M. heymonsi)、粗皮姬蛙(M. butleri)、穆氏姬蛙(M. mukhlesuri)和采集于伊洛瓦底江河谷中部的半干旱草原状平原的两个新种。为了探究姬蛙属系统进化关系,本研究测定了线粒体12S–16S rRNA基因片段,长度为2481 bp。同时结合分子、形态和声音等整合分类学方法评估缅甸姬蛙属的多样性。我们的研究表明,采集于马圭的姬蛙属物种是两个未被描述的新种。这两个同域分布的物种属于M. achatina种组,均分布于伊洛瓦底江谷的季节性干燥环境。其中Microhyla fodiens sp. nov. 体型粗壮并带有显著膨大的、呈铲状的外蹠突,用于挖掘,同时在分子上与同属其他已知物种具有较大分歧,遗传距离超过8.8%。Microhyla irrawaddy sp. nov. 是体型纤细的小型蛙类,与印度南部M. kodial是姊妹种(P-distance=5.3%)。然而Microhyla irrawaddy sp. nov. 在外部形态和声音等方面也与后者存在明显差异。穆氏姬蛙也是首次在缅甸被报道。我们进一步讨论了缅甸记录的姬蛙属物种的形态学特征和生物地理研究。

     

    Abstract: We present a morphological and molecular assessment of the Microhyla fauna of Myanmar based on new collections from central (Magway Division) and northern (Kachin State) parts of the country. In total, six species of Microhyla are documented, including M. berdmorei, M. heymonsi, M. butleri, M. mukhlesuri and two new species described from the semi-arid savanna-like plains of the middle part of the Irrawaddy (Ayeyarwady) River Valley. We used a 2 481 bp long 12S rRNA–16S rRNA fragment of mtDNA to hypothesize genealogical relationships within Microhyla. We applied an integrative taxonomic approach combining molecular, morphological, and acoustic lines of evidence to evaluate the taxonomic status of Myanmar Microhyla. We demonstrated that the newly discovered populations of Microhyla sp. from the Magway Division represent two yet undescribed species. These two new sympatric species are assigned to the M. achatina species group, with both adapted to the seasonally dry environments of the Irrawaddy Valley. Microhyla fodiens sp.nov. is a stout-bodied species with a remarkably enlarged shovel-like outer metatarsal tubercle used for burrowing and is highly divergent from other known congeners (P-distance≥8.8%). Microhyla irrawaddy sp. nov. is a small-bodied slender frog reconstructed as a sister species to M. kodial from southern India (P-distance=5.3%); however, it clearly differs from the latter both in external morphology and advertisement call parameters. Microhyla mukhlesuri is reported from Myanmar for the first time. We further discuss the morphological diagnostics and biogeography of Microhyla species recorded in Myanmar.
