To enrich the genomic database of Catantopinae (Orthoptera: Acrididae), mitogenomes of three species from different genera, Traulia nigritibialis (15,701 bp), Choroedocus capensis (16,293 bp) and Stenocatantops splendens (15,574 bp), were characterized and compared with those of other grasshoppers in the subfamily. All 13 protein-coding genes (PCGs) were initiated by ATN codons except COI with ACC (C. capensis and S.splendens) and ND6 with TTG (S. splendens). All transfer RNA (tRNA) genes had a typical clover-leaf structure, except tRNA in which the base pairs of the dihydrouridine (DHU) arm were reduced. The phylogenetic relationships were constructed among 22 species from four subfamiles of Acrididae by classical classifications based on two datasets of their mitogenomes using both Bayesian Inference (BI) and Maximum Likelihood (ML). The phylogenetic analysis confirmed the monophyly of the three other subfamilies, but did not provided support of the monophyly of Catantopinae.
为了丰富 Catantopinae （直翅目：蝗总科）的基因组数据库，对来自不同属的三种物种的线粒体基因组进行了研究，分别是 Traulia nigritibialis（15701 bp）、Choroedocus capensis（16293 bp）和 Stenocatantops splendens（15574 bp），并与该亚科的其他蝗虫的线粒体基因组进行了比较。所有 13 个蛋白质编码基因（PCGs）均以 ATN 密码子起始，除 COI 基因以 ACC（C.capensis 和 S.splendens）和 ND6 基因以 TTG（S.splendens）起始。所有转移 RNA（tRNA）基因均具有典型的三叶草结构，除 tRNA 外，其双氢尿嘧啶（DHU）臂的碱基对减少。基于两种数据集，通过贝叶斯推断（BI）和最大似然法（ML），对来自蝗总科四个亚科的 22 种物种进行了经典分类，构建了系统发育关系。系统发育分析证实了其他三个亚科的单系性，但不支持 Catantopinae 的单系性。
