We have determined the mitochondrial genome of Reticulitermes speratus kyushuensis Morimoto, 1968. The total length of the R. speratus kyushuensis is 15,898 bp with 65.3% A + T content. It consists of 13 protein–coding, 22 tRNA, 2 rRNA genes and an A+T–rich control region. All the protein–coding genes used ATN as start codon. But the stop codons were TAA, TAG, and an incomplete termination codon (T) abutting an adjacent tRNA gene. The A+T–rich control region was 1,105 bp in length with 67.8% A + T content
