This paper reported on new species from China which differs from other species of Homogryllacris in being without styli of male subgenital plate. The nearly complete mitochondrial genome (mitogenome), except control region, of the new species Homogryllacris parcibrevipenna was sequenced and analyzed. This partial mitogenome was 15509 bp in length and encoded 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and 2 ribosomal RNA unit genes. The gene arrangement and contents were consistent with other members of the Gryllacrididae. All the PCGs were started with the standard ATN codons except ND1 with TTG; and most of PCGs were terminated with a complete stop codon (TAA/TAG). Most tRNAs could be folded into the typical cloverleaf secondary structures, while tRNASer1 lacked a DHU stem. This data could enrich the genome information available for Gryllacrididae and facilitate phylogenetic studies of related insects. All the material were deposited in the Museum of Guangxi Normal University.
本文报道了来自中国的新种，与其他 Homogryllacris 物种不同，它的雄性外生殖器板没有 Stylus。新种 Parcibrevipenna 的近乎完整的线粒体基因组（mitogenome），除了控制区，已被测序并分析。这个部分的线粒体基因组长 15509bp，编码 13 个蛋白质编码基因（PCGs）、22 个转移 RNA 基因（tRNAs）和 2 个核糖体 RNA 单位基因。基因排列和含量与 Gryllacrididae 的其他成员一致。除了 ND1 用 TTG 外，所有的 PCGs 都以标准的 ATN 密码子开始；并且大多数 PCGs 都以完整的终止密码子（TAA/TAG）结束。大多数 tRNAs 可以折叠成典型的三叶草二级结构，而 tRNASer1 缺乏 DHU 茎。该数据可以丰富 Gryllacrididae 的基因组信息，并促进相关昆虫的系统发育研究。所有的标本都存放在广西师范大学博物馆。
