我们评估了更高级别的分类家庭Psocidae（昆虫纲：Psocodea：'Psocoptera'）的基础上，核18 S，组蛋白3，无翅和线粒体12 S，16 S和COI基因序列的组合分析。各种分析（包括/排除不完整的类群和/或快速进化的基因，数据分区，分析方法的选择）都提供了类似的结果，这通常是一致的关系推断使用形态观察。估计Psocidae的系统发育树的基础上，我们提出了一个修订后的更高层次的这个家庭的分类，虽然不确定性仍然存在关于这个分类的某些方面。这个分类包括一个基本的分裂成两个亚科，“Amphigerontiinae”（可能是并系的）和Psocinae。Amphigerontiinae分为Kaindipsocini（新部落），Blastini，Amphigerontini和Stylatopsocini。Psocinae分为Ptyctini（可能是并系），Psocini，Atrichadenotecnini（新族），Sigmatoneurini，Metylophorini和Thyrsophorini（后者包括以前被认为是Cerastipsocini的分类单元）。我们研究了对称/不对称的男性生殖器在这棵树的进化，发现这个字符是相当homoplasious。
We evaluated the higher level classification within the family Psocidae (Insecta: Psocodea: ‘Psocoptera’) based on combined analyses of nuclear 18S, Histone 3, wingless and mitochondrial 12S, 16S and COI gene sequences. Various analyses (inclusion/exclusion of incomplete taxa and/or rapidly evolving genes, data partitioning, and analytical method selection) all provided similar results, which were generally concordant with relationships inferred using morphological observations. Based on the phylogenetic trees estimated for Psocidae, we propose a revised higher level classification of this family, although uncertainty still exists regarding some aspects of this classification. This classification includes a basal division into two subfamilies, ‘Amphigerontiinae’ (possibly paraphyletic) and Psocinae. The Amphigerontiinae is divided into the tribes Kaindipsocini (new tribe), Blastini, Amphigerontini, and Stylatopsocini. Psocinae is divided into the tribes ‘Ptyctini’ (probably paraphyletic), Psocini, Atrichadenotecnini (new tribe), Sigmatoneurini, Metylophorini, and Thyrsophorini (the latter includes the taxon previously recognized as Cerastipsocini). We examined the evolution of symmetric/asymmetric male genitalia over this tree and found this character to be quite homoplasious.
