Taxonomy Of Hahniidae Spiders From Mt. Gaoligong, Yunnan Province, China (Araneae: Hahniidae)

Mt.Gaoligong is famous for its particular physiognomy and abundant resources of animals and plants.It has an integrated ecosystem, and being one of the international key regions of biologic resources and biodiversity.The present dissertation firstly gives comprehensive and systemic taxonomic research on 204 adult individual(♀133,(?)71) of Hahniidae (belongs to Arachinida,Araneae,Suborder Opisthothelae,Infraorder Araneomorphae) from Mt.Gaoligong.A total of 19 species of the genus Hahnia are reported,including 13 new species(Hahnia renaria sp.nov., H.yakouensis sp.nov.,H.aviformis sp.nov.,H.nujiangensis sp.nov.;H. applanata sp.nov.,H.heishanensis sp.nov.,H.pseudoapplanata sp. nov.,H.biglobulosa sp.nov.,H.concava sp.nov.,H.aurita sp.nov.,H. digitata sp.nov.,H.furcata sp.nov.,H.datangensis sp.nov.) and 1 interrogative species(Hahnia bivoluta).Detailed Chinese descriptions have been given to all species.2 chromophotograph were used,14 plates including 34 figs were drawn,and 5 plates including 15 figs were cited.Meanwhile,this paper introduced the research history and configuration characters of Hahniidae,and also the natural physiognomy and biodiversity state of the collection region.Statistical analysis of the vertical distribution of this family in Mt.Gaoligong and biodiversity research are provided:the number of the species belong to this family in these mountains occupied 57.78%of the total amount of species in this family in China(including 13 new species 1 interrogative species in this dissertation).The amount of the species and individuals live between altitude 2000m and 2500m is maximum,and above 3000m andbelow 1500m is minimum.In conclusion,most of Hahniidae spiders from Mt. Gaoligong distribute among high and mid altitude area.
