The family Buprestidae is one of the largest families in Coleoptera; however, the number of reported mitochondrial genomes for this family is limited.
In this study, mitogenomes of , , and were sequenced, assembled, and annotated. The mitogenomes of , and are reported for the first time.
The mitogenomes of , , and are complete, while the mitogenome of is partial, lacking trnV and 12S genes. The AT-skew of these four mitogenomes is positive (0.02-0.09). Among the protein-coding genes, the Ka/Ks ratio for cox1 is the lowest (0.05), and the nucleotide diversity for nd6 is the highest.
The phylogenetic trees based on mitogenome sequences suggest that the target genus is sister to , and the target genus is sister to ( + ( + )) clade. The results of this study will provide mitogenomic data for further research on the mitogenome and phylogeny of Buprestidae.
吉丁虫科是鞘翅目中最大的科之一；然而，该科已报道的线粒体基因组数量有限。
在本研究中，对[物种名称1]、[物种名称2]、[物种名称3]和[物种名称4]的线粒体基因组进行了测序、组装和注释。[物种名称2]、[物种名称3]和[物种名称4]的线粒体基因组首次被报道。
[物种名称1]、[物种名称2]和[物种名称3]的线粒体基因组是完整的，而[物种名称4]的线粒体基因组是部分的，缺少trnV和12S基因。这四个线粒体基因组的AT偏斜为正（0.02 - 0.09）。在蛋白质编码基因中，cox1的Ka/Ks比值最低（0.05），nd6的核苷酸多样性最高。
基于线粒体基因组序列的系统发育树表明，目标属[属名1]是[属名2]的姐妹群，目标属[属名3]是（[属名4] + （[属名5] + [属名6]））分支的姐妹群。本研究结果将为吉丁虫科线粒体基因组和系统发育的进一步研究提供线粒体基因组数据。
