Abstract
We sequenced and assembled the complete mitochondrial genome of Mnais tenuis from Darshi, Taoyuan County, Taiwan. The complete mitogenome of M. tenuis is 15,131 bp long, and contains 13 protein-coding, 22 tRNA, and two rDNA genes. Nucleotide compositions of the mitogenome of the M. tenuis are A: 40.08%, T: 25.47%, C: 20.38%, and G: 14.07%. The AT and GC skewness of the mitogenome sequence was 0.2228 and -0.183, showing the A-skew and C-skew. The clade including M. tenuis and all the other Odonata species received absolute support (100%). The phylogenetic position of Anisozygoptera is sister to Anisoptera. Mnais is phylogenetically close to Psolodesmus. Mitogenomic data from this study will provide useful information for further studies for the population genetics, speciation and conservation of M. tenuis in the future.
