The present paper deals with eight new species belonging to the family Araneidae collected from Wuling Mountains Area, Southwestern China. The diagnoses of these species are given below. Type specimens are deposited in the Institute of Zoology,Beijing. 1 Araneus auriculatus sp. nov. (fig. 1) Holotype,paratype 1,Badong(31. 0°N, 110. 3°E) ,Hubei Province,June 1,1989;allotype ,Badong,May 22,1989. Total length of females 4. 92-5. 48mm. Holotype 5. 48mm:cephalothorax1. 98mm long, 1.67mm wide;abdomen 3. 65mm long, 2. 94mm wide. Allotype 3. 36mm;cephalothorax 1. 61mm long,1. 52mm wide;andomen 1. 84mm long,1. 29mm wide. The new species resembles A. veperifer ,but may readily be distinguished from the latter by the epig-ynun with an ear-shaped lateral margin and the shape of abdomen. 2 Araneus badongensis sp. nov. (fig. 2) Holotype,paratypes 2,Badong,May 22,1989 Total length of males 3. 90-3. 94mm. Holotype 3. 90mm. cephalothorax 1. 94mm long, 1. 80mm wide;abdomen 2. 42mm long, 1. 57mm wide. This species appears to be related to A. guandisha-nensis Zhu et al, but differs from the latter in having a pair of projections on the shoulders of abdomen, and the shape of median apophysis of male palp different. 3 Araneus circellus sp. nov. (fig..3) Holotype ,Badong,May 22,1989. Total length of holotype 4. 68mm:cephalothorax 1. 98mm long. 1. 59mm wide; abdomen 2. 86mm long,2. 30mm wide. This new species is somewhat resemblance to A. dumetorum(Fourcroy) ,but differs from the latter in the different shape of epigynum. 4 Araneus colubrinus sp. nov. (fig. 4 ) Holotype,Badong,May 22,1989. Total length of holotype 5.16mm:cephalothorax 1. 75mm long,1.75mm wide;abdomen 3. 97mm long,3.41mm wide. This new species may be distinguished from other species of the genus Araneus by the shape of scape of epigynum. 5 Araneus octodentalis sp. nov. (fig. 5) Holotype,Badong,May 22,1989. Total length of male 4.30mm:cephalothorax 1. 94mm long, 1. 77mm wide;abdomen 2. 36mm long, 1. 94mm wide. This species is somewhat allide to A. bispinosus (Keyserling) ,but differs from the latter in the shape of median apophysis of male palp. 6 Araneus wulongensis sp. nov. (fig. 6) . Holotype,Wulong (29. 3°N,107. 7°E). Sichuan Province,June 14,1989. Total length of holotype 3. 88mm:cephalothorax 1. 45mm long , 1. 39mm wide; abdomen , 2. 58mm long,1. 94mm wide. This new species resembles A. auriculatvs,but differs from the latter in the shape of scape of eoigy-num. 7 Araneus xianfengensis sp. nov. (fig. 7) Holotype Xianfeng (29. 6°N,109. l°E),Hubei Province,June 4 ,1989,paratype 1,Badong May 21,1989. Total length of females 8. 89-10.32mm. Holotype 10. 32mm: cephalothorax 4. 13mm long, 133mm wide;abdomen 7. 14mm long,6. 11mm wide. The new species may be readily distinguished from its related species A. ancurus Zhu et al by its dorsal patch of the abdomen and the structure of epigynum. 8 Singa alpigenoides sp. nov. (fig. 8) Holotype,Hefeng(29. 8°N,110. 0°E) , Hubei Province,June 1,1989. Total length of holotype 5. 62mm:cephalothorax 2. 70mm long,2. 70mm,wide;abdomen 3.02mm long,2.07mm wide. This new species can be distinguished from S. alpigena Yin et al by male palp.
