Abstract
We sequenced the first complete mitochondrial genome for the aphid subfamily, Eriosomatinae, from a Rhus gall aphid, Schlechtendalia chinensis. The mitogenome of S. chinensis is 16,047 bp in length with a high A + T content of 84.2% and consists of 13 protein-coding genes, 24 tRNA genes including two extra tRNAPhe, two rRNA genes, a repeat region, and a control region. All protein-coding genes have a typical ATN initiation codon and TAA termination codon except COI and ND4, which terminate with a single T. All 24 tRNAs have the expected clover-leaf secondary structure and range in size from 62 to 73 bp. The lengths of rrnL and rrnS genes are 1274 and 772 bp, respectively. The repeat region is 335 bp and is uncommon among known aphid sequences for starting with a tRNAPhe. The control region is 705 bp in length and is located between rrnS and tRNAIle. We present a phylogeny of mitogenomes showing that S. chinensis is sister to Aphidinae.
