We describe the complete mitochondrial genomes of the green lacewing species Chrysoperla nipponensis (Okamoto, 1914) and Apochrysa matsumurae Okamoto 1912 (Neuroptera: Chrysopidae). The genomes were 16,057 and 16,214 bp in size, respectively, and comprised 37 genes (13 protein coding genes, 22 tRNA genes and two rRNA genes). A major noncoding (control) region was 1,244 bp in C. nipponensis and 1,407 in A. matsumurae, and the structure was simpler than that reported in other Neuroptera, lacking conserved blocks or long tandem repeats. The overall arrangement of genes was almost the same as that found in most arthropod mitochondrial genomes, with the one exception of a tRNA rearrangement to tRNA-Cys-tRNA-Trp-tRNA-Tyr, rather than the plesiomorphic tRNA-Trp-tRNA-Cys-tRNA-Tyr. A high A + T content (78.89 and 79.02%, respectively), A + T-rich codon bias, and a mismatch between the most-used codon and its corresponding tRNA anticodon were observed as a typical feature of the insect mitochondrial genome.
我们描述了绿尾大蚕蛾（Chrysoperla nipponensis）（Okamoto，1914）和 Apochrysa matsumurae Okamoto 1912（Neuroptera：Chrysopidae）的完整线粒体基因组。基因组大小分别为 16057 和 16214bp，包含 37 个基因（13 个蛋白编码基因、22 个 tRNA 基因和 2 个 rRNA 基因）。一个主要的非编码（控制）区在 C. nipponensis 中为 1244bp，在 A. matsumurae 中为 1407bp，其结构比其他神经翅目报道的更为简单，缺乏保守块或长串联重复。基因的总体排列几乎与大多数节肢动物的线粒体基因组相同，只有一个例外，即 tRNA 重排为 tRNA-Cys-tRNA-Trp-tRNA-Tyr，而不是原始的 tRNA-Trp-tRNA-Cys-tRNA-Tyr。高 A + T 含量（分别为 78.89%和 79.02%）、A + T 丰富的密码子偏好性以及最常用密码子与其相应 tRNA 反密码子之间的不匹配是昆虫线粒体基因组的一个典型特征。
