Type. Holotype ♀ (HNU, Lyco- Alop -0004-001): China, Gansu Province, Lanzhou City, Yuzhong County, Temple Majiamiao, 13.VII.1981, leg. Yingqiu Tang. Temple Majiamiao: 35°51'N , 104°7.12'E (information supplied by present authors). Diagnosis. Epigyne of this species is similar to that of A. chagyabensis Hu & Li, 1987, a species known from Xizang Autonomous Region of China. Both species are lacking anterior hood, have base of septum width much longer than septal stem length, both have distinct copulatory opening, but can be separated by septum width/length ratio 2.5 in A. disca and 1.8 in A. chagyabensis . Two species well differ by the shape of the endogyne (compare Fig. 1F-I and fig. 64-2 in Hu 2001 ). Figure 1. Alopecosa disca Peng, Yin, Zhang & Kim, 1997, female. A Habitus, dorsal view B eyes, front view C chelicera, ventral view D sternum, ventral view E epigyne F vulva G vulva, showing the detailed left half H vulva, moved slightly from the normal ventral view I vulva, showing the detailed right half. Abbreviations: Ag accessorial gland, Cd copulatory duct, Sb septal base, Sp spermatheca, Ss septal stalk. Scale bars: 1 mm ( A, B, D ); 0.5 mm ( C ); 0.1 mm ( E-I ). Description. Body (Fig. 1A ) length 16.0, carapace 7.9 long, 5.0 wide, abdomen 8.8 long, 5.8 wide (data from original description by Yin et al. 1997 : 64). Carapace dark reddish brown. Cervical and radial grooves distinct, darker than body color. Fovea linear, short, but a little thick. Head region wide, with anterior margin almost 4/5 width of thorax region. Anterior eye row straight, almost as wide as median one, posterior row widest. Eye sizes and inter-distances (Fig. 1A, B ): AME 0.30, ALE 0.27, PME 0.49, PLE 0.47; AME-AME 0.19, AME-ALE 0.2, PME-PME 0.49, PME-PLE 0.67. Clypeus height 0.23. Chelicerae black-brown, with three promarginal and two retromarginal teeth (Fig. 1C ). Both labium and endites black brown, with reddish brown distal parts. Sternum (Fig. 1D ) brown, with metallic luster. STL 3.52, STW 2.82 (Fig. 1D ). Palp and legs reddish brown, robust, without any distinct annuli. Leg measurements: I 18.30 (5.00, 6.60, 3.80, 2.90); II 16.70 (4.80, 5.80, 3.60, 2.50); III 15.00 (4.50, 5.00, 3.60, 1.90); IV 20.40 (6.10, 7.00, 5.00, 2.30) (data from original description by Yin et al. 1997 : 64), leg formula 4123. Dorsum of abdomen (Fig. 1A ) dark brown mixed yellowish brown. Cardiac mark distinct, dark brown and large. Posterior half of abdomen with 4 or 5 chevrons (because the type specimen has been wrinkled, chevron patterns showed in color photos of the present paper are not clearer than those showed in line drawings of the original paper). Venter of abdomen grey yellowish in the middle and dark grey laterally. Epigyne (Figs 1E-I , 2 ) wider than long. Atrium and anterior hood absent. Septum weakly sclerotized, with short stem ( Ss ) and broad base ( Sb ); stem shorter than base height. Spermathecae with clavate head, slender and curved stalk, and accessorial gland ( Ag ) situated at the place near copulatory duct. Copulatory ducts short, slightly twisted. Figure 2.
