Angaracris barabensis Pallas (Orthoptera: Acridoidea) is one of important pests in the grasslands in northern China. The complete mitochondrial genome of this insect was sequenced. This genome is 15,930 bp long, with an AT content of 75.5%, containing 37 typical animal mitochondrial genes and a AT-rich region. All genes were arranged in the same order as most of other Acridoidea. All 13 mitochondrial PCGs share the start codon ATN, and the usual termination codons (TAA) are found from 13 protein-coding genes, except for ND2, COII, ND3 (T). All of the 22 typical animal tRNA genes were found in A. barabensis mt-genome, and most of the tRNAs could be folded into the classic cloverleaf secondary structure except for tRNA-Ser (AGN), which lacks the dihydrouracil (DHU) stem. The sizes of the large and small ribosomal RNA genes are 1319 and 830 bp, respectively. The AT content of the AT-rich region is 85.6%.
