The genus Ultragryllacris is mainly distributed in China and Thailand, and the type species Ultragryllacris pulchra Gorochov & Dawwrueng, 2015 includes four subspecies. Up to now, these subspecies were identified mainly based on their morphological characteristics, and no study on the molecular identification of subspecies and phylogenetic analyses has been reported. Here we obtained three mitogenomes of U. pulchra rubricapitis and one mitogenome of Homogryllacris yunnana and reconstructed the relationship of Ultragryllacris among genera. Species identification was performed with ABGD, jMOTU, and NJ tree based on cox1 (658 bp) and cob (550 bp) genes. The mitogenomes of U. pulchra rubricapitis and H. yunnana were 15558-16625 bp and 16209 bp in length, respectively. Most of the PCGs started with the typical ATN codons and terminated with complete TAA/TAG. Four mitogenomes showed positive AT skews and negative GC skews. Besides, the phylogenetic tree of BI and ML revealed that Ultragryllacris was a monophyletic group. One geographical population of Ultragryllacris pulchra rubricapitis was described and illustrated.
该属主要分布于中国和泰国，模式种艳蟋 Ultragryllacris pulchra Gorochov & Dawwrueng, 2015 包括 4 个亚种。迄今为止，这些亚种主要是根据形态特征来鉴定的，尚未有亚种的分子鉴定和系统发育分析的研究报道。本研究获得了艳蟋红头亚种 U. pulchra rubricapitis 的 3 条线粒体基因组和 1 条云褐蟋 Homogryllacris yunnana 的线粒体基因组，重建了 Ultragryllacris 属内的亲缘关系。采用 ABGD、jMOTU 和基于 cox1（658 bp）和 cob（550 bp）基因的 NJ 树对物种进行了鉴定。U. pulchra rubricapitis 和 H. yunnana 的线粒体基因组长度分别为 15558-16625 bp 和 16209 bp。大多数 PCGs 以典型的 ATN 密码子起始，以完整的 TAA/TAG 终止。4 条线粒体基因组均表现出正的 AT 偏斜和负的 GC 偏斜。此外，BI 和 ML 的系统发育树表明，艳蟋是一个单系群。描述并绘制了艳蟋红头亚种的一个地理种群。
