A Study On The Taxonomy Of Spiders Of Clubionidae, Corinnidae And Liocranidae From China (Arachnida: Araneae)

The present paper deals with the Chinese species of families of spiders, namely, Clubionidae, Corinnidae and Liocranidae. The members of the families Corinnidae and Liocranidae were under the family of Clubionidae in the past and only became independent as separated families later. In the world these three families comprise 527 species of 5 genera, 831 species of 75 genera and 239 species of 32 genera, respectively. Totally, 78 species of 1 genera, 18 species of 7 genera and 19 species 4 genera were recorded in our fauna. In the paper 137 species of 13 genera belong to the three family from China are reported including 1 newly recorded genus from China, 1 new species group, 22 new species, 3 new records of species in China and 1 new discovery of the male. The study indicates that Geodrassus diguitusiformis Hu, 2001 should be transferred to the genus Trachelas; Clubiona heteroducta Zhang et Yin, 1998 and Clubiona xiningensis Hu, 2001 are synonymized with Clubiona gongi Zhang et al., 1997 and Clubiona neglecta O.P.-Cambridge, 1862 respectively.A review on classification and the species' distribution of the three families of spiders in China are also presented in the paper. Scanning electroscopy is used for study of the morphology of silk spigots and trichobothrial base in 32 species. The result indicates that the number of piriform gland spigot and aciniform gland spigot, with or without nubbin and cylindrical gland spigot, the number of cylindrical gland spigots, etc. are different in the three families. The trichobothrial sockets of species are different in the shape of the depression and the number of wrinkles on their surface.
