ABSTRACT An integrative taxonomic analysis recovered the new miniaturised species Microhyla tetrix sp. nov. of the M. superciliaris group as the sister species to M. superciliaris. The new species inhabits low-elevation to mid-elevation evergreen tropical forests of Ratchaburi, Phetchaburi, Prachuap Khiri Khan, Chumphon, Surat Thani and Krabi provinces of south-western Thailand. Additionally, our analysis supports the occurrence of M. superciliaris in Songkhla Province of southern Thailand. Our results underscore the important role of the Isthmus of Kra – a well-known biogeographic region of cladogenic turnover – in differentiation of the M. superciliaris species group. The description of Microhyla tetrix sp. nov. and the record of M. superciliaris brings the total number of species of Microhyla in Thailand to nine. Our work underlines the physiographic complexity of the Thai–Malay Peninsula and the need for intensified field surveys and integrative taxonomic studies for further exploration of its poorly understood herpetofauna. http://www.zoobank.org/urn:lsid:zoobank.org:pub:BDEAEAE3-D7C3-463C-B184-4F23C09252FA

1838 年，来自泰国泰纳塞林北部的 Microhyla Tschudi 属小型化窄口蛙的新种（两栖类：无尾目蛙科）

摘要 综合分类学分析恢复了新的小型化物种 Microhyla tetrix sp。十一月 M. superciliaris 群作为 M. superciliaris 的姊妹种。这种新物种栖息在泰国西南部的叻丕府、佛丕府、巴蜀府、春蓬府、素叻府和甲米府的低海拔至中海拔常绿热带森林中。此外，我们的分析支持在泰国南部宋卡省发生 M. superciliaris。我们的研究结果强调了克拉地峡——一个著名的生物地理区域的进化枝周转——在 M. superciliaris 物种群的分化中的重要作用。Microhyla tetrix sp. 的描述。十一月 M. superciliaris 的记录使泰国的小手足类动物总数达到九个。我们的工作强调了泰国 - 马来半岛的地形复杂性，以及需要加强实地调查和综合分类学研究，以进一步探索其知之甚少的疱疹动物群。http://www.zoobank.org/urn:lsid:zoobank.org:pub:BDEAEAE3-D7C3-463C-B184-4F23C09252FA
