Here, the complete mitochondrial genome (mitogenome) of Drawida gisti was sequenced and compared with the mitogenomes of other Metagynophora species. The circular mitogenome was 14,648 bp in length and contained two ribosomal RNA genes (rRNAs), 13 protein-coding genes (PCGs), and 22 transfer RNA genes (tRNAs). The types of constitutive genes and the direction of the coding strand that appeared in Drawida mitogenome were identical to those observed in other Metagynophora species, except for a missing lengthy non-coding region. The conservative relationships between Drawida species were supported by the overall analyses of 13 PCGs, two rRNAs, and 22 tRNAs. A comparison of the Metagynophora mitogenomes revealed that the ATP8 gene possessed the highest polymorphism among the 13 PCGs and two rRNAs. Phylogenetic analysis suggested that the Moniligastridae contained Drawida, which is a primitive Metagynophora group. Our study provides a step forward toward elucidating the evolutionary linkages within Drawida and even Metagynophora.

在这里，对Drawida gisti的完整线粒体基因组（有丝分裂基因组）进行了测序，并与其他 Metagynophora 物种的有丝分裂基因组进行了比较。环状有丝分裂基因组的长度为 14,648 bp，包含两个核糖体 RNA 基因 (rRNA)、13 个蛋白质编码基因 (PCG) 和 22 个转移 RNA 基因 (tRNA)。Drawida 有丝分裂基因组中出现的组成基因类型和编码链方向与在其他 Metagynophora 物种中观察到的相同，除了缺少长的非编码区。Drawida之间的保守关系13 个 PCG、2 个 rRNA 和 22 个 tRNA 的总体分析支持了物种。Metagynophora mitogenomes 的比较显示 ATP8 基因在 13 个 PCG 和两个 rRNA 中具有最高的多态性。系统发育分析表明，念珠蚧科包含Drawida，这是一个原始的Metagynophora 组。我们的研究为阐明Drawida甚至 Metagynophora内部的进化联系迈出了一步。
