Type.
Holotype ♀ (HNU, Lyco- Alop -0003-001): China, Qinghai Province, Xining City, 36°36'N, 101°48'E, 1978.
Diagnosis.
The female of this species is similar to that of Alopecosa zyuzini Logunov & Marusik, 1995 in having a pair of separate anterior hoods and similar shape of septum. Alopecosa orbisaca can be separated from similar species by having large size (carapace 4.0 vs 2.85-3.58 in A. zyuzini ), and wider stem of septum (septum wider than hood vs narrower than hood) (compare Fig. 3E View Figure 3 and fig. 64-2 in Hu 2001).
Description.
Holotype female. Body (Fig. 3A View Figure 3 ) length 9.20, carapace 4.00 long, 3.50 wide, abdomen 5.2 long, 3.20 wide (data from original description in Peng et al., 1997: 41). Carapace brown, with median pattern orange brown, short and about 1/4 width of thorax region. Cervical and radial grooves black brown, distinct. Pair of paraxial longitudinal bands brown, each band about 1/4 width of thorax region. Pair of lateral longitudinal bands also brown, however each band half of width of paraxial longitudinal band. Fovea long, linear, black. Cephalic region wide, with anterior margin about 3/4 width of thorax region. Anterior eye row straight, as wide as median one, posterior row widest. Eye sizes and interdistances (Fig. 3A, B View Figure 3 ): AME 0.14, ALE 0.16, PME 0.3, PLE 0.18; AME-AME 0.13, AME-ALE 0.11, PME-PME 0.35, PME-PLE 0.51. Clypeus height 0.19. Chelicerae black, with 3 promarginal (the first one largest and the third one smallest) and 2 retromarginal teeth (Fig. 3C View Figure 3 ). Labium with the base black and the distal part yellow and endites black-brown. Sternum yellow-brown, STL 1.94, STW 1.81 (Fig. 3D View Figure 3 ). Palps and legs reddish brown, robust, no distinct annulus except for femur of palp with dark stripes dorsally. Leg measurements: I 9.80 (2.90, 3.20, 2.00, 1.70); II 8.70 (2.80, 2.70, 1.90, 1.30); III 8.70 (2.80, 2.70, 1.90, 1.30); IV 11.30 (3.10, 3.50, 2.80, 1.90) (data from original description by Peng et al. 1997: 41). Abdomen yellow-brown, with large, pale cardiac and 5 brown chevron patterns dorsally (Fig. 3A View Figure 3 ). Venter of abdomen grey brown.
Epigyne (Figs 3E, F View Figure 3 , 4 View Figure 4 ) wide than long, with septum as long as wide, stem gradually widening toward the base, lateral margins of septum strongly sclerotized; anterior part of atrium with a pair of hoods (Ho); anterior part of septum (or stem, Ss) about 1.5 times wider than hoods. Spermatheca (Sp) divided distinctly into head and stalk, both of them with not smooth surface; a strong twist present at the connecting part between spermatheca and copulatory duct (Cd); copulatory duct long, ear-shaped.
Male. Unknown.
