The bamboo snout beetle (Coleoptera: Curculionidae) is a destructive forest pest and distributed widely in Southeast Asia. The 15,035 bp complete mitochondrial genome of the species consists of 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 21 transfer RNA genes (tRNAs) and a control region (GenBank accession no. MG674390). The gene was not found in the mitogenome. The gene order and the orientation of were similar to those found in other Coleoptera species. The nucleotide composition was significantly biased (A, G, C, and T was 38.18%, 10.10%, 16.16%, and 35.56%, respectively) with A + T contents of 73.74%. ATG, ATA, ATT, AAT, and TTG were initiation codons and TAA, TAG, and T were termination codons. All the 21 tRNAs displayed a typical cloverleaf secondary structure, except for which lacked the dihydrouridine arm. Phylogenetic analysis was performed using 13 PCGs with 14 other beetles showed that is closely related to , which agree with the traditional classification.
竹象甲（鞘翅目：象甲科）是一种具有破坏性的森林害虫，广泛分布于东南亚地区。该物种15035bp的线粒体基因组全长由13个蛋白质编码基因（PCGs）、两个核糖体RNA基因（rRNAs）、21个转运RNA基因（tRNAs）和一个控制区组成（GenBank登录号：MG674390）。在该线粒体基因组中未发现该基因。其基因排列顺序和方向与其他鞘翅目物种相似。核苷酸组成存在显著偏倚（A、G、C和T分别为38.18%、10.10%、16.16%和35.56%），A+T含量为73.74%。ATG、ATA、ATT、AAT和TTG为起始密码子，TAA、TAG和T为终止密码子。除缺少二氢尿嘧啶臂外，所有21个tRNA均呈现典型的三叶草二级结构。使用13个PCGs与其他14种甲虫进行系统发育分析表明，该竹象甲与该物种关系密切，这与传统分类一致。
