超目虱科在两个目：虱目（棘虱和书虱）和虱目（寄生虱）中有大约10,000个已描述的物种。已对一种书虫、bostrychophila Liposcelis和六种寄生虱进行了线粒体（mt）全基因组测序；这7个物种的mt基因组是昆虫中重组最多的。鳞翅目虱（lepidopsocid sp.）的mt基因组也已被测序，其重排程度远低于书虱和寄生虱。为了进一步了解psococodea中mt基因的重排，我们对psococerasttis albimaculata和Longivalvus hyalospilus这两种棘螈的mt基因组进行了测序，这两种棘螈是psocoorpha亚目的第一个代表，也是psocoorpha亚目中物种最丰富的亚目。我们发现，这两种巴棘的mt基因组是迄今为止在Psocodea中发现的重排最少的：一个蛋白质编码基因（nad3）和五个trna （trnN、trnS1、trnE、trnM和trnC）发生了移位。mt基因的重排可以用串联复制和随机缺失的两个事件来解释。mt基因组序列的系统发育分析支持Psocoptera是副系，而Phthiraptera是单系的观点。书虱（Troctomorpha亚目）与寄生虱关系最为密切。竹节子（原形亚目和原形亚目）关系密切，是一个单系类群。我们得出的结论是，在导致书虱和寄生虱的谱系中，mt基因重排要比导致竹节虱的谱系快得多。生活方式的改变似乎与两种Psocodea谱系之间mt基因重排的对比率有关。
The superorder Psocodea has ∼10,000 described species in two orders: Psocoptera (barklice and booklice) and Phthiraptera (parasitic lice). One booklouse, Liposcelis bostrychophila and six species of parasitic lice have been sequenced for complete mitochondrial (mt) genomes; these seven species have the most rearranged mt genomes seen in insects. The mt genome of a barklouse, lepidopsocid sp., has also been sequenced and is much less rearranged than those of the booklouse and the parasitic lice. To further understand mt gene rearrangements in the Psocodea, we sequenced the mt genomes of two barklice, Psococerastis albimaculata and Longivalvus hyalospilus, the first representatives from the suborder Psocomorpha, which is the most species-rich suborder of the Psocodea. We found that these two barklice have the least rearranged mt genomes seen in the Psocodea to date: a protein-coding gene (nad3) and five tRNAs (trnN, trnS1, trnE, trnM and trnC) have translocated. Rearrangements of mt genes in these two barklice can be accounted for by two events of tandem duplication followed by random deletions. Phylogenetic analyses of the mt genome sequences support the view that Psocoptera is paraphyletic whereas Phthiraptera is monophyletic. The booklouse, L. bostrychophila (suborder Troctomorpha) is most closely related to the parasitic lice. The barklice (suborders Trogiomorpha and Psocomorpha) are closely related and form a monophyletic group. We conclude that mt gene rearrangement has been substantially faster in the lineage leading to the booklice and the parasitic lice than in the lineage leading to the barklice. Lifestyle change appears to be associated with the contrasting rates in mt gene rearrangements between the two lineages of the Psocodea.
