过去对啮虫目昆虫的分类依赖于形态特征。啮虫目通常分为三个亚目：Trogiomorpha、Troctomorpha和Psychomorpha。传统的分类将扁头亚目分为四个下目（Homilopsocidea，Caeciliusetae，Psocetae和Epipsocetae），但最近的形态学分支研究从Homilopsocidea中删除了Archipsodae，从Psocetae中删除了Hemipsodae。我们调查了系统发育的关系，在亚目Padorpha使用的DNA序列从核18S和线粒体16S，12S和细胞色素氧化酶I基因。这些基因序列的系统发育分析支持单系的果蝇。此外，单系的传统亚组Caeciliusetae和Psocetae的普遍支持。Homilopsocidea的单系性不被支持，而Archipsocus从这个组中删除。虽然分子系统发育与最近的形态学特征的分支研究基本一致，但我们没有发现任何证据表明半啮虫科应该从Psocetae中删除。
Previous classification of the insect order Psocoptera has relied on morphological characters. Psocoptera are generally divided into three suborders: Trogiomorpha, Troctomorpha, and Psocomorpha. Traditional classification divides the Psocomorpha into four infraorders (Homilopsocidea, Caeciliusetae, Psocetae and Epipsocetae), but a recent morphological cladistic study removed Archipsocidae from Homilopsocidea and Hemipsocidae from Psocetae. We investigated the phylogenetic relationships within the suborder Psocomorpha using DNA sequences from the nuclear 18S and mitochondrial 16S, 12S and cytochrome oxidase I genes. Phylogenetic analyses of these gene sequences supported monophyly for Psocomorpha. In addition, monophyly of the traditional subgroups Caeciliusetae and Psocetae was generally supported. Monophyly of Homilopsocidea was not supported, and Archipsocus is removed from this group. Although the molecular phylogeny is generally consistent with recent cladistic studies of morphological characters, we found no evidence that Hemipsocidae should be removed from Psocetae.
