Etymology. The specific name is a patronym in honor of Doctor Guo Tang, who contributed with many papers on spider taxonomy in China.
Diagnosis. Males of this species can be easily identified (Figs 3C −F, 5C −G, 6A −D) by the blunt tip of broad median apophysis, the presence of a hook-shaped tibial apophysis, a thumb-like cymbial apophysis ventrally and a long posterior cymbial apophysis dorsally. The female is different from any other congeneric species by its genital area (Figs 4C–D, 6E–F), with very small and long C-shaped sclerotized loops and clear bell-shaped hood.

Carapace reddish-brown (Fig. 3A), with radial grooves. Eye field square, covered with short yellow hairs. Fovea round, hollowed. Chelicerae yellowish-brown (Fig. 3B), with typical dentition: 2 promarginal teeth and 1 large bifurcated retromarginal tooth (Fig. 5B). Endites yellowishbrown (Fig. 3B), with abundant hairs on anterior inner margin, slightly longer than wide. Labium oval (Fig. 3B), yellowish-brown, with a few strong setae on anterior margin. Sternum reddish-brown (Fig. 3B). Measurements of legs: I 3.16 [0.99, 0.74, 0.79, 0.35, 0.29]; II 2.21 [0.68, 0.32, 0.48, 0.43, 0.30]; III 2.32 [0.67, 0.30, 0.48, 0.55, 0.32]; IV 3.28 [0.98, 0.41, 0.79, 0.75, 0.35]. Leg formula: IV, I, III, II. Femur I width 0.32; femur II width 0.22. Leg spination: I: Tibia p v 0-3-0, r v 0-3-0; Metatarsus p v 1 -0-1, r v 1 -0-1. Abdomen oval (Figs 3A, B), dorsum dark yellowish-gray, with two pairs of patches on anterior part, an obvious transverse light band on the medial part, and six lighter herringbone strips on posterior part. Spinnerets yellowish-brown (Fig. 3B), with abundant brown hairs. Palp (Figs 3C −F, 5C −G, 6A −D) with a short, hook-shaped tibial apophysis and a thumb-like cymbial apophysis, a long posterior apophysis on dorsal cymbium, all of them appressed to cymbium. Spiral embolus short, extending along the margin of the broad median apophysis.
Female (Figs 4, 6E–F). Total length 3.65, CL 1.73, CW 1.12, AL 1.79, AW 1.09. EL 0.99; AERW 1.14, AMEW 0.78, PERW 1.14, PMEW 1.02. Abdomen (Figs 4A, B), with lighter and slender herringbone strip. Measurements of legs: I 3.15 [0.98, 0.76, 0.81, 0.35, 0.25]; II 2.34 [0.78, 0.35, 0.48, 0.46, 0.27]; III 2.56 [0.77, 0.33, 0.56, 0.61, 0.29]; IV 3.64 [0.97, 0.49, 0.88, 0.87, 0.43].
