The complete sequence of the mitochondrial genome of Podagrion sp. (Hymenoptera: Torymidae) is described. The mitogenome was 15,845 bp in size, and contained typical sets of mitochondrial genes. The base composition of the Podagrion sp. mitogenome was also biased toward A + T bases (81.8%). The mitochondrial genome of Podagrion sp. has a weak AT skew (0.07) and a strong GC skew (-0.26). Podagrion sp. exhibits a novel rearrangement compared with the ancestral order, including six protein-coding genes (nad3, cox3, atp6, atp8, cox2 and cox1), which have inverted to the minor strand from the major strand. The A + T-rich region of Podagrion sp., which is located between trnN and trnI, have five tandem repeats. The apomorphic rearrangements, including the conserved block "cox3-atp6-atp8-cox2-cox1-nad5-nad4-nad4l-nad6-cob" and the special locations of trnV and trnA, were mapped onto the phylogeny of Proctotrupomorpha.
描述了 Podagrion sp.（膜翅目：Torymidae）线粒体基因组的完整序列。该线粒体基因组大小为 15845bp，包含典型的线粒体基因。Podagrion sp. 的碱基组成也偏向 A+T 碱基（81.8%）。Podagrion sp. 的线粒体基因组具有较弱的 AT 倾斜（0.07）和较强的 GC 倾斜（-0.26）。与祖先顺序相比，Podagrion sp. 表现出一种新的重排，包括六个蛋白编码基因（nad3、cox3、atp6、atp8、cox2 和 cox1），它们从主链倒转为小链。Podagrion sp. 的 A+T 丰富区位于 trnN 和 trnI 之间，有五个串联重复。拟态重排，包括保守块“cox3-atp6-atp8-cox2-cox1-nad5-nad4-nad4l-nad6-cob”和 trnV 和 trnA 的特殊位置，被映射到 Proctotrupomorpha 的系统发育上。
