The mitochondrial genome of the Pristaulacus compressus (Spinola, 1808) (Hymenoptera: Aulacidae) (GenBank accession No. KF500406) is reported in this study. This is the first sequenced mitochondrial genome from the family Aulacidae of the order Hymenoptera. The length of this mitochondrial genome is 15,563 bp with an A + T content of 84%, including 13 protein-coding, 2 rRNA and 22 tRNA gene, and an A + T-rich region (Table 1). Three tRNA and one protein-coding genes were rearranged in the P. compressus mitochondrial genome, in which, the trnY was inverted, while the trnQ was shuffled to the downstream of tRNA cluster trnI-trnQ-trnM. The trnS1 was translocated to the downstream of the A + T-rich region together with the protein-coding gene nad1. The gene arrangement pattern of this mitochondrial genome is new to the Hymenoptera. All protein-coding genes start with ATN start codon. Ten protein-coding genes stop with termination codon TAA, whereas one protein-coding gene uses incomplete stop codon TA and two use T. The A + T-region is located between rrnS and trnS1 with a length of 780 bp.
