The complete mitochondrial genome of (Odonata: Zygoptera: Coenagrionidae) and phylogenetic analysis.

is ubiquitous in south China and is particularly easy be found in some rice fields. In this study, we sequenced and analyzed the complete mitochondrial genome (mitogenome) of . This mitogenome was 15,350 bp long and encoded 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs) and two ribosomal RNA unit genes (rRNAs). The nucleotide composition of the mitogenome was biased toward A and T, with 74.0% of A + T content (A 42.1%, T 31.9%, C 14.6%, G 11.4%). Gene order was conserved and identical to most other previously sequenced Zygoptera dragonflies. Most PCGs of have the conventional start codons ATN (seven ATG, two ATT, and two ATC), with the exception of and (TTG). Except for four PCGs (, , , and ) end with the incomplete stop codon T--, all other PCGs terminated with the stop codon TAA. Phylogenetic analysis showed that got together with the same family species (, , , ) with high support value. The relationships (Megapodagrionidae + ((Calopterygidae + (Euphaeidae + Pseudolestidae)) + (Coenagrionidae + Platycnemididae))) were supported within Zygoptera.
