Taxonomy Of The Liocranidae From China (Arachnida:Araneae)

Liocranidae is member of Dionycha,belongs to Order Araneae of Class Arachnida,currently,which has been reported 275 species in 32 genera all over the world.At present,there are 46 species belong to 8 genera,including 16 species in seven genera reported from China before this research.This dissertation deals with a comprehensive systematics research of Chinese Liocranidae,briefly studies the research history,taxonomic system,distribution patterns and biology,also detailed describes the diagnostic characteristics and morphological characteristics,and with a more comprehensive summary and supplement about the Chinese species of the Liocranidae.We initially solve the problem of the extremely small number of species of the Liocranidae in China,and expand the record of the geographical distribution of it,laying a foundation for the following study in China.In total,there are 61 figures in the paper,50 figures of photographs and 11 figures of illustrations included.In the taxonomic part,46 species of 8 genera are described in this dissertation,including one newly recorded genus(Koppe Deeleman-Reinhold,2001),four newly recorded species of two genera(Agroeca brunnea(Blackwall,1833),Agroeca coreana Namkung,1989,Agroeca dentigera Kulczy?ski,1913,Sphingius punctatus Deeleman-Reinhold,2001),and 26 new species(Agroeca mainlingensis sp.n.,Agroeca lata sp.n.,Agroeca nigra sp.n.,Agroeca tumida sp.n.,Agroeca batangensis sp.n.;Jacaena sp.1,Jacaena bannaensis sp.n.,Jacaena sp.3,Jacaena sp.5,Jacaena sp.7;Oedignatha sp.2,Oedignatha sp.3,Oedignatha sp.4,Oedignatha sp.5,Oedignatha sp.6,Oedignatha sp.7,Oedignatha sp.8,Oedignatha sp.9;Paratus hamatus Mu & Zhang,2018,Paratus kentingensis Mu & Zhang,2018,Paratus sp.1,Paratus sp.2,Paratus sp.3;Koppe jinghongensis sp.n.;Sphingius sp.1,Sphingius sp.2).Compared to works before this study,there are 16 species of 7 genera in China,a total of one genus and 30 species have been added.Additionally,we examined two species Agroeca debilis and Agroeca flavens from Xinjiang of China described by O.Pickard-Cambridge and checked the original description in literature carefully,we ensure that these two species should belong to Gnaphosidae.But we do not examine the holytype of these two species because the original specimen can't be found,we decide to treat them as nomina dubia.We would not count then in this research finally...
