The complete mitochondrial genome of a stonefly species, Etrocorema hochii (Plecoptera: Pelidae)

The mitochondrial genome of Etrocorema hochii (Wu, 1938), the first representative of Etrocorema, was sequenced and annotated in this study. The complete circular mitochondrial genome (mitogenome) was 15,854 bp in length using Illumina sequencing and harboured 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), two ribosomal RNA genes (rRNA), and one control region in the typical stonefly gene order. The nucleotide composition of this genome is A (36.0%), T (31.4%), C (20.9%), and G (11.7%). All PCGs use the typical start codon ATN, except ND1, ND2, and COI, which start with TTG, GTG, and ACC, respectively. Only the ND5 genes terminated with single T––, and the rest use the stop codon TAA/TAG. We used this new nucleotide information under Bayesian and maximum-likelihood analyses to explore the relationships of Pelidae. Phylogenetic analyses showed that E. hochii is closely related to the clade (Togoperla + Kamimuria), which is widely accepted view.
