The complete mitochondrial genome of Schizoneuraphis gallarum van der Goot, 1917 (Hemiptera: Aphididae: Hormaphidinae)

In this study, the complete mitochondrial genome of Schizoneuraphis gallarum was sequenced and annotated. The mitogenome is 14,990 bp in length with an A + T content of 82.6%, including 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and a control region. This is the shortest aphid mitogenome reported so far. All the protein-coding genes are initiated with ATN codon and terminated with TAA codon except cox1 and nad4 which are terminated with T. All the transfer RNA genes can form the typical clover-leaf secondary structure except trnS (AGN). The maximum-likelihood phylogenetic tree based on mitogenome sequences of 25 aphid species shows that S. gallarum is sister to Hormaphis betulae.
