Background The taxonomic status of the Thai populations belonging to the Limnonectes kuhlii species complex is controversial, due to phenotypic similarity in the cryptic species complex. Recently, some studies on this group in Thailand have discovered four new species: L. taylori, L. megastomias, L. jarujini and L. isanensis. Even so, the diversity of this group is still incomplete. New information Based on an integrative approach encompassing genetic and morphological analyses, we conclude that the Limnonectes populations from Nan Province (northern) and Yala Province (southern) of Thailand are conspecific with L. bannaensis Ye, Fei & Jiang, 2007 and L. utara Matsui, Belabut & Ahmad, 2014, respectively. These are the first records of these species in Thailand. Our study highlights the importance of using DNA sequence data in combination with morphological data to accurately document species identity and diversity. This is especially important for morphologically cryptic species complexes and sympatrically occurring congeners.

泰国有牙蛙 Limnonectes bannaensis Ye, Fei & Jiang, 2007 和 L. utara Matsui, Belabut & Ahmad, 2014 (Amphibia: Anura: Dicroglossidae) 的首次记录

背景 由于神秘物种复合体的表型相似性，属于 Limnonectes kuhlii 物种复合体的泰国种群的分类地位是有争议的。最近，在泰国对该群体的一些研究发现了四个新种：L. taylori、L. megastomias、L. jarujini 和 L. isanensis。即便如此，这个群体的多样性仍然是不完整的。新信息 基于包含遗传和形态分析的综合方法，我们得出结论，泰国南省（北部）和也拉省（南部）的 Limnonectes 种群与 L. bannaensis Ye、Fei & Jiang, 2007 和 L. utara 同种Matsui、Belabut 和 Ahmad，分别于 2014 年。这些是这些物种在泰国的首次记录。我们的研究强调了将 DNA 序列数据与形态数据结合使用以准确记录物种身份和多样性的重要性。这对于形态上神秘的物种复合体和同域出现的同源物尤其重要。
