Complete mitochondrial genome and phylogenetic position of the gall aphid <i>Chaetogeoica ulmidrupa</i> (Hemiptera: Aphididae)

We sequenced two complete mitochondrial genomes of Chaetogeoica ulmidrupa, a gall-forming aphid on Pistacia chinensis. Each genome consists of 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a control region, with a strong A+T bias (∼85%). All protein-coding genes initiate with ATN codon and terminate with TAA, except for ND4 and COX1 ending with a single T. Phylogenetic analysis strongly supported that C. ulmidrupa was sister to C. yunlongensis and together they formed a clade with Slavum lentiscoides, all three species of which feed on the primary host plant P. chinensis to form galls.
