The mitochondrial genome of a stonefly species, Cerconychia sapa (Plecoptera: Styloperlidae)
The nearly complete sequence of the mitochondrial DNA (mtDNA) of the stonefly, Cerconychia sapa, has been completed and annotated in this study. The circular genome is 15,188 bp in length with an A+T content of 71.2%, and contains 13 PCGs, 22 tRNA genes and 2 rRNA subunit genes. The control region can only be assembled partially. All PCGs use normal start codon ATN, while ND1 and ND5 use TTG and GTG as start codon, respectively. Meanwhile, 12 PCGs use the typical termination codons TAN, except ND5, which stopped with the incomplete terminaton signal T. Phylogenetic analysis suggests that C. sapa is closely related to Styloperla sp. and S. spinicercia. Our results provide basic data for further study of phylogeny in Plecoptera.
