The red-necked longhorn beetle is a major pest of peach orchards. In this study, we sequenced and analyzed the complete mitochondrial genome (mitogenome) of . This mitogenome was 15,760 bp long and encoded 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs) and two ribosomal RNA unit genes (rRNAs). Gene order was conserved and identical to most other previously sequenced Cerambycidae. Most PCGs of have the conventional start codons ATN (six ATT, five ATG and one ATC), with the exception of (TTG). Except for three genes (, and ) end with the incomplete stop codon T-, all other PCGs terminated with the stop codon TAA or TAG. The whole mitogenome exhibited heavy AT nucleotide bias (74.3%). Phylogenetic analysis positioned in a well-supported clade within the subfamily Cerambycinae with (tribe Xystrocerini). These results support the currently accepted taxonomy and provide a better understanding of the phylogenetic analysis of the Cerambycidae.
红颈天牛是桃园的主要害虫。在本研究中，我们对……的完整线粒体基因组（线粒体基因组）进行了测序和分析。该线粒体基因组长度为15760 bp，编码13个蛋白质编码基因（PCGs）、22个转运RNA基因（tRNAs）和两个核糖体RNA单位基因（rRNAs）。基因顺序保守，与大多数其他先前测序的天牛科相同。……的大多数PCGs具有传统的起始密码子ATN（六个ATT、五个ATG和一个ATC），……（TTG）除外。除了三个基因（……、……和……）以不完整的终止密码子T - 结尾外，所有其他PCGs均以终止密码子TAA或TAG结束。整个线粒体基因组表现出强烈的AT核苷酸偏向性（74.3%）。系统发育分析将……置于天牛亚科内一个得到充分支持的分支中，与……（Xystrocerini族）在一起。这些结果支持了目前被接受的分类法，并为更好地理解天牛科的系统发育分析提供了依据。
