The complete mitochondrial genome of <i>Glischrochilus (Librodor) japonius</i> (Coleoptera: Nitidulidae)

<i>Glischrochilus japonius</i> is a type of forestry pest that causes damage to various garden plants. In this study, the complete mitogenome of <i>G. japonius</i> was sequenced for the first time., The circular mitogenome comprises of 15,357 bp with an AT content of 77.51%, including 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes and one control region. The genera of the analyzed beetles from Nitidulidae in phylogenetic relationships are monophyletic. The mitochondrial genome structure of <i>G. japonius</i> is stable and conformed, and resolving the phylogenetic relationships amongst the sap beetles requires continued accumulation and improvement of mitogenome data.
