The complete mitochondrial genome of <i>Leptomastidea bifasciata</i> (Hymenoptera: Chalcidoidea: Encyrtidae) and phylogenetic analysis

<i>Leptomastidea</i> (Hymenoptera, Encyrtidae) are parasitoids of agricultural/forestry mealybug pests. This study first sequences and annotates <i>L. bifasciata</i>’s complete mitochondrial genome (15,768 bp), which contains 13 PCGs, 22 tRNAs, 2 rRNAs. All 13 PCGs start with ATN (ATT, ATG, ATA); most end with TAA, except ND1 (TAG). Phylogenetic analysis shows <i>L. bifasciata</i> is sister to <i>Anagyrus</i> spp.

<i>细索跳小蜂属（Leptomastidea）</i>隶属于膜翅目（Hymenoptera）跳小蜂科（Encyrtidae），为农林粉蚧类害虫的寄生性天敌。本研究首次完成了<i>双带细索跳小蜂（L. bifasciata）</i>完整线粒体基因组的测定与注释，该基因组全长15768 bp，包含13个蛋白编码基因（protein-coding genes, PCGs）、22个转运RNA（transfer RNA, tRNA）及2个核糖体RNA（ribosomal RNA, rRNA）。13个蛋白编码基因均以ATN（ATT、ATG、ATA）作为起始密码子；绝大多数以TAA作为终止密码子，仅NADH脱氢酶亚基1（ND1）以TAG作为终止密码子。系统发育分析结果表明，双带细索跳小蜂与长角跳小蜂属（Anagyrus）物种互为姊妹群。
