梨须隐翅虫属Oedichirus Erichson,1839与环腹隐翅虫属Procirrus Latreille,1829均隶属于鞘翅目Coleoptera,隐翅虫科Staphylinidae,毒隐翅虫亚科Paederinae,切须隐翅虫族Pinophilini,环腹隐翅虫亚族Procirrina。它们是一类中至大型隐翅虫,捕食小型节肢动物,喜潮湿环境,常生活在溪水边或森林里的落叶层中,与人类关系密切,是生态系统中不可或缺的一部分。梨须隐翅虫属广布于古北区、东洋区、大洋区、新热带区和古热带区,目前全世界共记载395种,中国记载13种;环腹隐翅虫属29种,广布于古北区、东洋区、大洋区和古热带区,中国仅记载原产于孟加拉的1个种,分布于香港和台湾。中国梨须隐翅虫属和环腹隐翅虫属的相关报道多为外国学者发表,国内研究基础比较薄弱,尚无系统性的研究总结。本研究通过检视采自全国9个省份的标本,用传统形态分类学方法,对中国梨须隐翅虫属和环腹隐翅虫属进行了系统性的整理与总结,结果如下:一、共记录中国梨须隐翅虫属16种,其中包括新种11种,即:勐仑梨须隐翅虫O.menglunensis sp.nov.、七娘梨须隐翅虫O.qiniangensis sp.nov.、那邦梨须隐翅虫O.nabangensis sp.nov.、刘氏梨须隐翅虫O.liushengnanae sp.nov.、伪黑梨须隐翅虫O.falsinigellus sp.nov.、倒钩梨须隐翅虫O.hamus sp.nov.、胡氏梨须隐翅虫O.hujiayaoi sp.nov.、勐龙梨须隐翅虫O.menglongensis sp.nov.、茂兰梨须隐翅虫O.maolanensis sp.nov.、金秀梨须隐翅虫O.jinxiuensis sp.nov.。已知种5种:阿氏梨须隐翅虫O.astoni Rougemont,2017、长翅梨须隐翅虫O.longipennis Kraatz,1859、赤焰梨须隐翅虫O.flammeus Koch,1939、彭中梨须隐翅虫O.pengzhongi Li,Xie&Li,2015、大明梨须隐翅虫O.damingensis Li,Xie&Li,2015。环腹隐翅虫属3种,其中包括新种1种:海南环腹隐翅虫P.hainanensis sp.nov.;中国新记录种1种:孟加拉环腹隐翅虫P.fusculus Sharp,1889;已知种1种:莱氏环腹隐翅虫P.lewisii Sharp,1889。二、详细描述了所有物种,讨论了它们与近缘种的区分要点,并配有相应的整体图和解剖图。三、构建了世界梨须隐翅虫属和环腹隐翅虫属数据库。四、编制了中国梨须隐翅虫属和环腹隐翅虫属名录。五、编写了中国梨须隐翅虫属和环腹隐翅虫属分种检索表。六、分析了梨须隐翅虫属和环腹隐翅虫属的地理分布特征。

Members of the staphylinid genera Oedichirus Erichson,1839 and Procirrus Latreille,1829(Coleoptera: Staphylinidae: Paederinae: Pinophilini: Procirrina)can be commonly found in leaf litter layer of forest or surroundings near stream.The body size of them are medium to large.All the species are predators feeding on small invertebrates in damp environment.They play important roles in ecosystem and have a close relationship with human beings.They are also regarded as an entomological indicator of environment and an important part of natural resources.At present,395 species of Oedichirus have been known worldwide including Palaearctic region,the Oriental region,the Australian region,the Neotropic region and the Paleotropical region.Among them,13 species are recorded from China.There are29 species of Procirrus have been known worldwide,widely scattered in the Palaearctic region,the Oriental region,the Australian region,and the Paleotropical region.One species originally described from Bangladesh are also recorded from Hongkong and Taiwan.Relevant reports on Oedichirus and Procirrus in China are mostly published by foreign scholars.The domestic research foundation is relatively weak,and there is no systematic research on these groups.By examining specimens collected from 9provinces of China,using traditional morphological taxonomic methods,a taxonomic study on Chinese species of Oedichirus and Procirrus is treated here.The results of the study can be summarized as follows:1.Sixteen species of Oedichirus were recognized,of which eleven species are new species: O.menglunensis sp.nov.,O.qiniangensis sp.nov.,O.nabangensis sp.nov.,O.liushengnanae sp.nov.,O.falsinigellus sp.nov.,O.hamus sp.nov.,O.hujiayaoi sp.nov.,O.menglongensis sp.nov.,O.maolanensis sp.nov.,O.jinxiuensis sp.nov.;of which five species are known species: O.astoni Rougemont,2017,O.longipennis Kraatz,1859,O.flammeus Koch,1939,O.pengzhongi Li,Xie & Li,2015,O.damingensis Li,Xie & Li,2015.Three species of Procirrus were recognized,of whichone new species: P.hainanensis sp.nov.;one new record of China species: P.fusculus;one known species: P.lewisii.2.All species treated in this paper were described in detail and compared with related species.Habitus and major diagnostic characters for all species were illustrated.3.Databases of the genera Oedichirus and Procirrus were built.4.Lists for Chinese species of Oedichirus and Procirrus were provided.5.Keys to Chinese species of Oedichirus and Procirrus were separately presented.6.The distributions of Oedichirus and Procirrus in china were mapped,and their distributional pattern were analyzed.
