Abstract
The complete mitochondrial genome of Xya japonica (Haan, 1842), which was collected from Hebei province of China, is reported here. It is 15,352 bp in length and contains 71.2% AT. All X. japonica protein-coding sequences start with a typical ATN codon except for the cytochrome oxidase subunit I (cox1), which start with CCG. The usual termination codon TAA and TAG were found from 13 protein-coding genes. All tRNA genes have the typical clover leaf structure, excluding trnS(AGN) that lacks the dihydrouracil arm. The sizes of the large and small ribosomal RNA genes are 1289 and 747 bp, respectively. The AT content of the A + T-rich region is 75.0%. The orientation and gene order of the X. japonica mitogenome is identical to Ellipes minuta and Gryllotalpa orientalis, there is no phenomenon of “DK rearrangement” which has been wide reported in Caelifera.
