The complete mitochondrial genome of Neuroctenus taiwanicus (Hemiptera: Aradidae)

Neuroctenus taiwanicus Kormilev, 1955 is a flat-bodied and enigmatic bug that was first discovered on the island of Taiwan, China. In this study, the whole mitochondrial genome of N. taiwanicus was sequenced and annotated for the first time, and its genomic data were uploaded to Genbank feedback number OR675057. The mitochondrial genome of N. taiwanicus is 15,340 bp in length, a typical circular DNA encoding 37 genes and a control region with 68.4% A + T content. The phylogeny reveals the taxonomic status of N. taiwanicus, which is most closely related to N. yunnanensis, and demonstrates the sister relationship among Neuroctenus, Mezira, and Brachyrhynchus. In addition, the results also confirm that Aradinae and Calisiinae are the earliest branching and more primitive in the family Aradidae, which is consistent with the analysis of the traditional classification.台湾扁蝽（Neuroctenus taiwanicus）Kormilev, 1955是一种体躯扁平、形态隐秘的蝽类昆虫，最初于中国台湾岛被发现。本研究首次完成了台湾扁蝽完整线粒体基因组的测序与注释工作，并将其基因组数据上传至GenBank（基因库），登录号为OR675057。该线粒体基因组全长15340 bp，为典型的环状DNA分子，共编码37个基因及一段控制区，A+T碱基含量为68.4%。系统发育分析明确了台湾扁蝽的分类地位：其与云南扁蝽（N. yunnanensis）的亲缘关系最为密切；同时揭示了扁蝽属（Neuroctenus）、肩扁蝽属（Mezira）与短喙扁蝽属（Brachyrhynchus）之间的姊妹群关系。此外，本研究结果还证实，扁蝽科（Aradidae）内的扁蝽亚科（Aradinae）与卡利扁蝽亚科（Calisiinae）为最早分化的类群，演化地位更为原始，这与传统分类学的分析结果一致。
