Type materials.
Holotype: China • ♂; Yunnan Province, Dali Bai Autonomous Prefecture, Jingdong Yi Autonomous County, Jinping Township, Yubishan Park; 24°27.01'N, 101°49.53'E; ca 1270 m elev.; 16.VIII.2015; X.Q. Mi et al. leg.; TRU- Araneidae -268. Paratypes: 3♀♀; same data as for holotype; TRU- Araneidae -269-271.
Etymology.
The specific name is a noun in apposition and refers to the type locality.
Diagnosis.
The new species resembles G. spinipes in appearance and genitalia structures, but it can be distinguished as follows: 1) median apophysis not exceeding the conductor in prolateral view and retrolateral view (Fig. 2A, B View Figure 2 ) vs exceeding the conductor (Fig. 4A, B View Figure 4 ); 2) visible part of embolus curled about 90° in ventral view (Fig. 2C View Figure 2 ) vs about 180° (Fig. 4C View Figure 4 ); 3) conductor shorter, extending ventrally and not exceeding prolateral margin of pedipalp in ventral view (Fig. 2C View Figure 2 ) vs longer, extending ventro-prolaterally and the tip exceeding the prolateral margin of pedipalp (Fig. 4C View Figure 4 ); 4) copulatory openings situated on inner edges of the depressions (Fig. 1A View Figure 1 ) vs on anterior lateral edges (Fig. 3A View Figure 3 ); 5) lateral epigynal plates not covering the anterior rim in lateral view (Fig. 1B View Figure 1 ) vs covering the anterior rim (Fig. 3B View Figure 3 ); and 6) female carapace lacking dark brown patches (Fig. 1E, G View Figure 1 ) vs having dark brown patches (Fig. 3G, I View Figure 3 ).
Description.
Male (holotype, Figs 1H-J View Figure 1 , 2 View Figure 2 , 7A-D View Figure 7 ). Total length 3.80. Carapace 2.25 long, 1.90 wide. Abdomen 1.90 long, 1.45 wide. Clypeus 0.05 high. Eye sizes and interdistances: AME 0.15, ALE 0.08, PME 0.15, PLE 0.15, AME-AME 0.13, AME-ALE 0.03, PME-PME 0.20, PME-PLE 0.18, MOA length 0.53, anterior width 0.38, posterior width 0.45. Leg measurements: I 8.85 (2.75, 2.65, 2.40, 1.05), II 8.35 (2.60, 2.45, 2.30, 1.00), III 4.55 (1.55, 1.30, 1.10, 0.60), IV 7.05 (2.35, 2.00, 1.90, 0.80). Carapace yellow, with inconspicuous gray patches in thoracic region; base of eyes black. Cervical groove inconspicuous; fovea longitudinal. Chelicerae yellow, with four promarginal and three retromarginal teeth. Endites wider than long, yellow, with very narrow, dark anterior edges. Labium triangular, yellow. Sternum cordiform, yellow, with a wedge-shaped white patch posteriorly. Legs yellow to yellowish brown, with inconspicuous annuli; femur I with 12 macrosetae; tibia I with 12 macrosetae; tibia II with seven macrosetae; tibia III with seven macrosetae; tibia IV with seven macrosetae. Abdomen shield-shaped, ~1.31 × longer than wide, grayish yellow, dorsal with a pair of dark brown patches anterolaterally and a dark brown folium posteriorly. Venter abdomen yellow with gray patches. Spinnerets yellow with gray tip.
Pedipalp (Fig. 2 View Figure 2 ): paracybium fingerlike; median apophysis bifurcated; dorsal ramus weaker than the ventral one; embolus thick at base, twisted and tapered into a fine tip; conductor membranous, curled, about 2 × longer than wide in retrolateral view.
Female (paratype TRU- Araneidae -269, Fig. 1A-G View Figure 1 ). Total length 5.05. Carapace 2.35 long, 2.00 wide. Abdomen 3.00 long, 2.35 wide. Clypeus 0.08 high. Eye sizes and interdistances: AME 0.15, ALE 0.08, PME 0.18, PLE 0.18, AME-AME 0.15, AME-ALE 0.03, PME-PME 0.33, PME-PLE 0.35, MOA length 0.58, anterior width 0.43, posterior width 0.65. Leg measurements: I 8.45 (2.45, 2.80, 2.20, 1.00), II 8.35 (2.45, 2.75, 2.15, 1.00), III 5.10 (1.65, 1.60, 1.15, 0.70), IV 8.00 (2.60, 2.55, 2.00, 0.85). Habitus similar to that of male, but abdomen with a pair of low anterolateral humps and sternum with a throughout paler patch.
Epigyne (Fig. 1A-D View Figure 1 ): ~1.36 × wider than long in ventral view, with a distinct median septum separating two depressions; copulatory openings situated on inner edges of the depressions; copulatory ducts widest at the beginning part, a bit longer than spermatheca; spermathecae almost S-shaped in dorsal view, not touching.
