Abstract
The complete mitochondrial genome of Gryllotalpa unispina was 15,513 bp in length and contained 70.9% AT. All G. unispina protein-coding sequences except for the nad2 started with a typical ATN codon. The usual termination codons (TAA) and incomplete stop codons (T) were found from 13 protein-coding genes. All tRNA genes were folded into the typical cloverleaf secondary structure, except trnS(AGN) lacking the dihydrouridine arm. The sizes of the large and small ribosomal RNA genes were 1245 and 725 bp, respectively. The A + T-rich region was 917 bp in length with 76.8%. The orientation and gene order of the G. unispina mitogenome were identical to the G. orientalis and G. pluvialis, there was no phenomenon of “DK rearrangement” which has been widely reported in Caelifera.
