A Systematic Taxonomic Study On The Species Group Of C. Lepidopteran And C. Lepidopteran In China

The intricatus-group and multipunctatus-group belong to Coleoptera,Staphylinidae,Staphylininae,Quediina,genus Quedius,and subgenus Raphirus.Both of the two groups have unique metallic luster,and the head and pronotum have additional punctures,so they can be quickly distinguished by the others.Their main habitat is on damp stones in streams in forests,or on damp moss near waterfalls.They are widely distributed and have a relatively fixed ecological environment.They are predatory insects and feed on other smaller arthropods,which can effectively promote the material cycle of the ecosystem and maintain the dynamic balance of the ecosystem.Previously,there were 21 species of intricatus-group species recorded in the world,distributed in the Palaearctic and Oriental regions,of which 18 species were recorded in China,mainly in the southern provinces of China.There were 16 species of multipunctatus-group,also distributed in the Palaearctic and Oriental regions.Among them,13 species have been recorded in China,and also mainly distributed in the southern provinces of China.However,due to the fact that domestic scholars have little research on intricatus group and multipunctatus-group,there are still many areas lacking research,and still many undiscovered species need to be described.It is necessary to carry out a systematic investigation and research to improve the information gap of these two species groups in our country.In this study,by examining some types and specimens from 14 provinces(Zhejiang,Fujian,Jiangxi,Henan,Hubei,Hunan,Guangxi,Hainan,Chongqing,Sichuan,Guizhou,Yunnan,Shaanxi,Taiwan)and comparing them with relevant literature,Chinese species of intricatus-group and multipunctatus-group were systematically studied as follows:1.A total of 23 species were recorded in this study,including 18 species of intricatus-group: Q.(R.)maoxingi Hu et al.,2012,Q.(R.)nigror Smetana,2014,Q.(R.)kurosawai Shibata,1986,Q.(R.)jindrai Smetana,1998,Q.(R.)rubor Smetana,2014,Q.(R.)caesar Smetana,2014,Q.(R.)taiwanensis Shibata,1986,Q.(R.)barbarossa Smetana,2002,Q.(R.)nesonaster Smetana,2014,Q.(R.)bisignatus Smetana,2002,Q.(R.)zhoui Zheng,2003,Q.(R.)cupreogutta Smetana,2014,Q.(R.)xiaobini sp.nov.,Q.(R.)cupreonotus Smetana,2014,Q.(R.)distigma Smetana,2014,Q.(R.)cupreostigma Smetana,2014,Q.(R.)pengi sp.nov.,Q.(R.)torrentum Smetana,2002,including 2new species;and 5 species of multipunctatus-group: Q.(R.)leigongshanensis Li et al.,2007,Q.(R.)viridimicans Smetana,2009,Q.(R.)collinsi Smetana,2009,Q.(R.)nabanhensis Hu et al.,2012,Q.(R.)puetzi Smetana,1998.2.All the species were described in detail;their main differences between similar species were discussed;their habitus and major diagnostic features were illustrated.3.Database of the world's intricatus-group and multipunctatus-group species were built.4.Keys to the world's intricatus-group and multipunctatus-group were separately presented.5.Lists of the world's intricatus-group and multipunctatus-group species were provided.6.Geographic distribution maps of world's intricatus-group and multipunctatus-group species were made.
