Type material.
Holotype ♂ (TRU- Araneidae -136), China: Hunan Province, Shaoyang City, Suining County, Zhaishi Township, Huangsang National Nature Reserve (26°23.51'N, 110°9.56'E, ca 1620 m), 11.VII.2022, X.Q. Mi & C. Wang leg. Paratypes: 1♂2♀ (TRU- Araneidae -137-139), same data as for holotype; 2♂4♀ (TRU- Araneidae -140-145), Guizhou Province, Qiandongnan Miao and Dong Autonomous Prefecture, Leishan County, Danjiang Township, Leigongshan National Nature Reserve (26°22.99'N, 108°12.08'E, ca 1990 m), 20.VII.2017, C. Wang et al. leg.; 1♂ (TRU- Araneidae -146), Jiangxi Province, Ji’an City, Anfu County, Taishan Township, Wugongshan (27°27.50'N, 114°10.08'E, ca 1270 m), 23.VI.2022, Z.G. Huang et al. leg.
Etymology.
The specific name is derived from the Chinese pinyin “fenzhi”, meaning branched, referring to the threadlike branch of the embolus.
Diagnosis.
The new species resembles A. albabdominalis Zhu, Zhang, Zhang & Chen, 2005 in having pale green coloration in life and a similar shape of the median apophysis and conductor, but it can be distinguished as follows: 1) epigyne scape not twisted into an S-shape vs S-shaped ( Zhu et al. 2005: fig. 3B); 2) copulatory openings wedge-shaped in ventral view vs round ( Zhu et al. 2005: fig. 3B); 3) embolus of male pedipalp U-shaped in prolateral view vs straight ( Zhu et al. 2005: fig. 3D); 4) the branch on the embolus is threadlike vs lamellar ( Zhu et al. 2005: fig. 3D); and 5) carapace unicolor vs with a pair of lateral longitudinal patches ( Zhu et al. 2005: fig. 3A).
Description.
Male (holotype, Figs 1I, J View Figure 1 , 2B-D View Figure 2 , 9A-D View Figure 9 ; paratype TRU- Araneidae -138, Fig. 2A, E View Figure 2 ). Total length 3.35. Carapace 1.75 long, 1.20 wide. Abdomen 2.10 long, 1.65 wide. Clypeus 0.10 high. Eye sizes and interdistances: AME 0.10, ALE 0.06, PME 0.11, PLE 0.06, AME-AME 0.15, AME-ALE 0.15, PME-PME 0.13, PME-PLE 0.20, MOA length 0.33, anterior width 0.35, posterior width 0.33. Leg measurements: I 6.90 (2.05, 2.40, 1.70, 0.75), II 6.45 (1.95, 2.20, 1.60, 0.70), III 3.60 (1.20, 1.10, 0.80, 0.50), IV 5.25 (1.70, 1.70, 1.30, 0.55). Carapace pear-shaped, yellow; base of eyes brown. Cervical groove inconspicuous; fovea longitudinal. Chelicerae yellow; four promarginal and three retromarginal teeth. Endites almost square, yellow with very narrow, dark anterior edge, with tooth-like process laterally. Labium triangular, yellow. Sternum cordiform, yellow with dark setae. Legs yellow to brown, without annuli; femur I with eight macrosetae; tibia I with 10 macrosetae; tibia II with 12 macrosetae; tibia III with nine macrosetae; tibia IV with seven macrosetae. Abdomen oval, ~1.3 × longer than wide, yellowish green with pale yellow spots; venter whitish green. Spinnerets yellowish brown.
Pedipalp (Fig. 2 View Figure 2 ) with a basal femoral protrusion; patella with two bristles; median apophysis almost triangular, with a single long, slender, curved spur and a shorter broad spur; embolus twisted into a U-shape, with a threadlike branch at base, without cap (see arrows in Fig. 2A, E View Figure 2 ); conductor membranous, with a spur at base; terminal apophysis blunt, with dense denticles.
Female (paratype TRU- Araneidae -137, Fig. 1A-H View Figure 1 ). Total length 4.40. Carapace 2.35 long, 1.85 wide. Abdomen 2.80 long, 2.55 wide. Clypeus 0.10 high. Eye sizes and interdistances: AME 0.11, ALE 0.08, PME 0.13, PLE 0.08, AME-AME 0.18, AME-ALE 0.25, PME-PME 0.15, PME-PLE 0.33, MOA length 0.40, anterior width 0.40, posterior width 0.38. Leg measurements: I 8.30 (2.45, 2.95, 2.05, 0.85), II 7.70 (2.25, 2.70, 1.95, 0.80), III 4.75 (1.55, 1.50, 1.05, 0.65), IV 6.85 (2.25, 2.30, 1.60, 0.70). Habitus similar to that of male, but abdomen ~1.1 × wider than long.
Epigyne (Fig. 1A-D View Figure 1 ) ~1.65 × wider than long; scape with nearly parallel sides, spoon shaped distally; copulatory openings wedge shaped in ventral view, near posterior margin; copulatory ducts coiled ~360°, ~2 × longer than a spermatheca diameter; spermathecae spherical, ~1/4 spermatheca diameter apart.
Variation.
Total length: ♂♂ 2.95-3.40 (n = 5); ♀♀ 4.15-5.65 (n = 6). Preserved specimens grayish white. The embolic branch is generally broken off.
Distribution.
Hunan, Guizhou, Jiangxi.
Comment.
The oval abdomen is similar to that of members of the A. ejusmodi group, but the long, distally spoon-shaped scape differs greatly than in those species, and thus the group to which the new species belongs is unclear.
