Figulus binodulus Waterhouse is a small stag beetle distributed in East Asia. We determined the first mitochondrial genome of F. binodulus of which is 16,261-bp long including 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and a single large noncoding region of 1,717 bp. Gene order of F. binodulus is identical to the ancestral insect mitochondrial gene order as in most other stag beetle species. All of 22 tRNAs could be shaped into typical clover-leaf structure except trnSer1. Comparative analyses of 21 Lucanidae mitochondrial genomes was conducted in aspect of their length and AT-GC ratio. Nucleotide diversities analyses provide that cox1 and cox2 in Lucanidae are less diverse than those of Scarabaeoidea. Fifty simple sequence repeats (SSRs) were identified on F. binodulus mitochondrial genome. Comparative analysis of SSRs among five mitochondrial genomes displayed similar trend along with SSR types. Figulus binodulus was sister to all other available family Lucanidae species in the phylogenetic tree.

无花果完整线粒体基因组的综合分析（鞘翅目：Lucanidae）


Figulus binodulus Waterhouse 是一种分布于东亚的小型锹虫。我们确定了F. binodulus的第一个线粒体基因组，其长度为 16,261 bp，包括 13 个蛋白质编码基因、2 个核糖体 RNA 基因、22 个转移 RNA 和一个 1,717 bp 的大非编码区。与大多数其他锹虫物种一样， F. binodulus的基因顺序与祖先昆虫线粒体基因顺序相同。除trnSer1外，22个tRNA均可形成典型的三叶草结构。对21个Lucanidae线粒体基因组的长度和AT-GC比进行了比较分析。核苷酸多样性分析表明，Lucanidae 中的cox1和cox2 的多样性低于 Scarabaeoidea 中的多样性。在F. binodulus线粒体基因组上鉴定出 50 个简单序列重复 (SSR)。对五个线粒体基因组之间的 SSR 的比较分析显示出与 SSR 类型相似的趋势。 Figulus binodulus是系统发育树中所有其他可用的 Lucanidae 科物种的姐妹。
