Type material: Holotype ♂ (SWUC-T-LY-08-01), China, Sichuan Province, Pingwu County, Wanglang National Nature Reserve , 33°00.205′N, 104°01.296′E, 2949 m, 22.V. 2013, D. Wang & X.K. Jiang leg. GoogleMaps Paratypes: 17♂ and 30♀ (SWUC-T-LY-08-02~48), same data as holotype GoogleMaps .
Etymology. The specific name is an adjective from the Latin word ‘ hamatus’, meaning ‘hamate’ or ‘hook-like’, referring to the shape of the median apophysis.
Diagnosis. The species can be easily distinguished from other Artoria species by the hook-shaped median apophysis and the arched embolus, with bifurcated end ( Figs 5A–C View FIGURE 5 , 6C–G View FIGURE 6 ). Females can be recognized by the wide copulatory openings of epigyne ( Figs 5D View FIGURE 5 , 6H–I View FIGURE 6 ).
Description. Male. Total length 5.20–5.90. Holotype ( Fig. 6A View FIGURE 6 ) total length 5.48. Carapace 2.97 long, 2.12 wide; opisthosoma 2.57 long, 1.99 wide. Carapace brown. Eye region black. Radial furrows distinct. Eye sizes and interdistances: AME 0.09, ALE 0.13, PME 0.32, PLE 0.27; AME–AME 0.08, AME–ALE 0.07, PME–PME 0.25, PME–PLE 0.30. Clypeus 0.13 high. Chelicerae brown, with three teeth on both margins. Labium yellowish brown, with dark base, longer than wide. Endites yellowish brown, longer than wide. Sternum dark brown and scutellate, with sparse brown setae. Legs yellowish brown, with dark brown pigmentation. Leg measurements: I 6.70 (1.84, 2.33, 1.50, 1.03); II 6.40 (1.79, 2.15, 1.47, 0.99); III 6.12 (1.72, 1.92, 1.55, 0.93); IV 8.60 (2.22, 2.63, 2.46, 1.29). Abdomen yellowish brown, dorsally with lanceolate cardiac mark in anterior half followed by irregular black markings extending posteriorly. Venter of abdomen brown, with brown spinnerets.
Pedipalp ( Figs 5A–C View FIGURE 5 , 6C–G View FIGURE 6 ). Median apophysis sclerotized, hook-shaped anteriorly, longer than wide, and with pointed end. Basoembolic apophysis highly sclerotized, slightly curved with blunt end. Terminal apophysis with two arms, one of them needle-like as the functional conductor (TA1); the other one sclerotized, relatively broad at base, curved distally (TA2). Embolus longer than wide, arched, distal end bifurcated.
Female ( Fig. 6B View FIGURE 6 ). Total length: 7.85. Carapace 3.34 long, 2.35 wide; opisthosoma 4.26 long, 3.31 wide. Eye sizes and interdistances: AME 0.09, ALE 0.12, PME 0.35, PLE 0.27; AME–AME 0.12, AME–ALE 0.12, PME–PME 0.28, PME–PLE 0.36. Clypeus 0.17 high. Leg measurements: I 7.03 (2.05, 2.48, 1.51, 0.99); II 6.74 (1.96, 2.35, 1.46, 0.97); III 6.72 (1.82, 2.07, 1.73, 1.10); IV 9.37 (2.42, 2.83, 2.72, 1.40). Leg formula: 4123.
Female genitalia ( Figs 5D–E View FIGURE 5 , 6H–J View FIGURE 6 ). Epigyne septum wide, oval. Copulatory openings wide. Copulatory ducts thick and long. Head of spermathecal small and club-like, extending forward. Fertilization ducts wide and slightly distorted.
Distribution. Currently known only from the type locality, Wanglang Nature Reserve, Sichuan Province, China ( Fig. 11 View FIGURE 11 ).
