This study determined the first complete mitochondrial genome (mitogenome) of a stonefly, Scopura longa (Plecoptera: Scopuridae), and reconstructed a phylogeny based on two datasets of mitogenomes in eighteen available stoneflies to examine the relationships among Plecoptera. The complete mitogenome of S. longa is a circular molecule of 15,798 bp in size. It contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and a control region (CR). Most PCGs used standard ATN start codons and TAN stop codons. All tRNAs could be folded as typical cloverleaf secondary structures except tRNA(Ser(AGN)), with the dihydrouridine (DHU) arm missing. Tandem repeat regions, two potential stem-loop (SL) structures, Poly T structures and G + C-rich regions are detected in the control region. Finally, the phylogenetic relationships among the families within the Arctoperlaria were reconstructed. The topological structures of the two trees were almost identical. The present phylogenetic analysis shows that S. longa belongs to the infraorder Euholognatha. The monophyly of each family is generally well supported based on nucleotide sequences. The Pteronarcyidae is sister to ((Peltoperlidae + Styloperlidae) + (Perlidae + (Perlodidae + Chloroperlidae))). (C) 2018 Elsevier B.V. All rights reserved.
