隐翅虫属Priochirus Sharp(鞘翅目：隐翅虫科)是一类游动甲虫，其头部结构特别是头部前缘的牙齿有很大的变异。本文分析了灵长类Priochirus Sensu Lato属10个亚属之间的系统发育关系，以及Priochirus与Leptochirini族其他属的系统发育关系。对62个成虫形态性状进行了支序分析。结果表明，该属不是一个单系群，它分为两个谱系(这里分别称为谱系I和谱系II)。亚属Euleptarthus Jakobson包括日本亚属、长角亚属和马来亚属3个种组，为多系种。系统I对应于Leiochirus+(Exochirus+Syncampsochirus)+(Eutriacantus+(Plastus+(Plaonicus-group of Euleptarthus+(Barychirus+Stigmatochirus)分支，与Thoracochirus Bernhauer属形成姊妹群。谱系II对应于Priochirus、S、Str.+(Cephalmerus+(Euleptarthus的长角类和马来亚类))支系。此外，分析还揭示了谱系I和Thoracochirus属的代表之间的姐妹关系。在系统发育分析的基础上，对该属进行了系统发育分析。11月亚属和一新亚属亚属--亚属亚属。Nov.，这是为以前的Euleptarthus亚属的日本群而建立的。重新定义了尖头潜蝇属Priochirus Sharp Sensu novo，包括谱系II的亚属。中国记述了7个新种：Plastus(SinumandiBulus)Curvaticornis，sp.11月产于四川；直角类Plastus(Sinumandibulus)，sp.11月产于湖北；新种Priochirus(Euleptarthus)amblyodontus，sp.11月产于湖南；宝兴普氏线虫Priochirus(Euleptarthus)baingingensis，sp.11月产于四川的细毛虫Priochirus(Euleptarthus)拉长，sp.11月产于贵州的细角隐翅虫Priochirus(Euleptarthus)parvicornis，sp.11月产于福建和尖顶新种Priochirus(Euleptarthus)oxgonus，sp.11月来自海南。
The genus Priochirus Sharp (Coleoptera: Staphylinidae) is a rove beetle group with great variation in cephalic structures, especially the teeth on the frontal margin of head. In this paper, phylogenetic relationships among ten subgenera of the genus Priochirus sensu lato, and of Priochirus and other genera of the tribe Leptochirini are analysed. A cladistic analysis was conducted based on 62 characters of adult morphology. Results indicate that the genus Priochirus is not a monophyletic group and is divided into two lineages ( called here Lineages I and II respectively). The subgenus Euleptarthrus Jakobson, which included three species-groups (japonicus, longicornis and malayanus), is shown to be polyphyletic. Lineage I corresponds with the Leiochirus + (Exochirus + Syncampsochirus) + (Eutriacanthus + (Plastus + (japonicus- group of Euleptarthrus + (Barychirus + Stigmatochirus)))) clade and forms a sister group to the genus Thoracochirus Bernhauer. Lineage II corresponds with the Priochirus, s. str. + (Cephalomerus + (longicornis- and malayanus-group of the Euleptarthrus)) clade. In addition, the analysis reveals sister relationships between representatives of Lineage I and the genus Thoracochirus. On the basis of phylogenetic inference, the genus Plastus Bernhauer, stat. nov. is proposed to include the subgenera of Lineage I and a new subgenus Sinumandibulus, subgen. nov., which is erected for the japonicus- group of the former subgenus Euleptarthrus. The genus Priochirus Sharp sensu novo is redefined to include the subgenera of Lineage II. Seven new species are described from China: Plastus (Sinumandibulus) curvaticornis, sp. nov. from Sichuan; Plastus (Sinumandibulus) recticornis, sp. nov. from Hubei; Priochirus (Euleptarthrus) amblyodontus, sp. nov. from Hunan; Priochirus (Euleptarthrus) baoxingensis, sp. nov. from Sichuan, Priochirus (Euleptarthrus) elongates, sp. nov. from Guizhou, Priochirus (Euleptarthrus) parvicornis, sp. nov. from Fujian and Priochirus (Euleptarthrus) oxygonus, sp. nov. from Hainan.
