【Abstract】 The present paper deals with five species of spiders collected from Guangx- i,China.They are Araneus tubabdorninus sp.nov.;Larinia phthisica(L.Koch,1871); Neoscona elliptica Tikader et Bal,1981;Zygiella guangxiensis sp.nov.;Zygiella nadleri Heimer,1984=Zygiella melanocrania Yin et al.,1990(nec Zygiella melanocrania (Thorell,1881).All type specimens are deposited in Hebei Educational College. 1.Araneus tubabdominus Zhu et Zhang,sp.nov.(Figs.1—7) Holotype ♀,allotype ♂,paratypes 2♀♀,Longzhou County(25°1′N,115°0′E), August,1980;paratype 1 ♀,Luzhai County(24°24′N,109°42′E),August,1981. Total length of female(Holotype)12.1mm.Cephalothorax 4.1mm long,2.8mm wide;abdomen 9.1mm long,4.5mm wide.Diameters of eyes(in mm):AME 0.20,ALE 0.13,PME 0.13,PLE 0.13.Female total length varies from 10.5 to 12.1mm.Total length of male(allotype)3.9mm.Cephalothorax 4.4mm long,3.9mm wide;abdomen 5.0mm long,2.9mm wide.The dorsal pattern of female abdomen,the shape of epigynum and palp are shown in figs.1—7. This new species resembles Araneus elongatus,but may be distingushed from the lat- ter by having a long scape of epigynum. 2.Larinia phthisica(L.Koch,1871)(figs.8—13) Larinia phthisica(L.Koch,1871)(Tanikawa, 1983:36—40,figs.15—21). Total length of female 7.4—11.8mm.Total length of male 5.38—6.02mm. Specimens examined:1 ♂,Hepu County,August,1980;1♂,Bama County, November,1981;3♀♀、1♂,Tiandong County,August,1980. 3.Neoscona elliptica Tikader et Bal,1981(figs.14—20) Neoscona elliptica Tikader et Bal,1981:24—25,figs.45—49. Total length of female 5.2—6.0mm.Total length of male 3.0—4.2mm. Specimens examined:1♀,Hepu County,July,1980;3♀♀,Gulping County,Au- gust,1980;6♀♀,Tiandong County,August,1980;2♀♀、2♂♂,Bobai County,Au- gust,1980;2♀♀,Liucheng County,July,1980;1♀、1♂,Pingnan County,August, 1981. 4.Zygiella guangxiensis Zhu et Zhang,sp.nov.(figs.21—27) Holotype ♀,allotype ♂,paratypes 2♀♀,Shanglin County(23°24′N,108°30′E), August,1981;paratypes 7♀♀,Bose County (23°54′N,106°36′E),August,1986;1♀, Mt.Ningming(23°24′N, 108°30′E),August,1980. Total length of female(Holotype)4.9mm.Cephalothorax 2.0mm long,1.6mm wide;abdomen 3.1mm long,2.5mm wide.Diameters of eyes(in mm):AME 0.13,ALE 0.10,PME 0.10,PLE 0.08.Female total length varies from 3.4 to 4.9mm.Total length of male(allotype)4.1mm.Cephalothorax 1.8mm long,1.7mm wide;abdomen 2.4mm long,1.9mm wide.The dorsal pattern of female abdomen,the shapes of epigynum and palp are shown in figs.21—27. The epigynal shape of this species is similar to Zygiella calyptrata(Workman,1894), the differences are as followings:(1)the copulatory bubes is shorter than those of the latter’s,(2)the fourth coxa has not a posterior distal spine as the latter has. 5.Zygiella nadleri Heimer,1984(figs.28—31) Zygiella nadleri Heimer,1984:95—97,figs.1—6. Zygiella melanocrania-Yin et al.,1990:138—139,figs.344—346,(nec Zygiella melanocrania(Thorell,1887). Total length of female 4.2—7.3mm.Total length of male 5.2—5.8mm. Specimens examined:1♀、1♂,Luchuan County,August,1981;1♂.Bose County, 20 August,1980;1♀,Tianyang County,August,1981;2♀♀,Jinxiu County,March, 1987;3♀♀,Fusui County,August,1980;1♀,Guiping County,August,1980.更多还原
