Abstract
In this study, we reported the complete mitochondrial genome of the dragonfly Brachythemis contaminate (Odonata: Libellulidae). The entire circular genome is 15,056 bp in length and represents the smallest in presently known odonatan mitogenomes. The DNA molecule contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a non-coding control region of 323 bp. There were a total of 137 bp short intergenic spacers and 89 bp overlaps in the genome. The gene arrangement is similar to other dragonflies. The base composition of the genome is A (40.2%), T (32.8%), C (15.6%) and G (11.4%) with an AT content of 73.0%. Four start codons (ATA, ATT, ATC and ATG) and two stop codons (TAG and TAA/TA) were found in 13 protein-coding genes. The length of 22 tRNA genes ranged from 63 (trnP) to 72 bp (trnK).
