Type material.
Holotype ♂ (IZCAS-Ar41715), CHINA: Yunnan, Xishuangbanna, Mengla County, Menglun Township, Menglun Nature Reserve, G213 roadside (21°53.65'N, 101°16.98'E, 589 m alt.), 26.XI.2009, G. Tang et al. leg. Paratypes: 3♂1♀ (IZCAS-Ar41716-41719), same data as holotype.
Etymology.
The specific name is a patronym in honour of the late Prof. Changmin Yin, one of the pioneers of spider taxonomy in China; noun (name) in genitive case.
Diagnosis.
Eriovixia yinae sp. nov. resembles E. pseudocentrodes ( Bösenberg & Strand, 1906) by the copulatory organs, but can be distinguished from the latter by: 1) median plate keeled vs. not keeled ( Mi et al. 2010: fig. 12); 2) spermathecae separated from each other vs. touching ( Mi et al. 2010: figs 11 and 13); 3) posterior edge of PMEs and anterior edge of ALEs of male almost in a line in dorsal view vs. recurved ( Mi et al. 2010: fig. 10); and 4) retrolateral branch of median apophysis with parallel margins in apical view vs. widest at distal end ( Mi et al. 2010: figs 14-15).
Description.
Male (holotype, Figs 11A-D View Figure 11 , 18B View Figure 18 , 19F View Figure 19 , 20F View Figure 20 ). Total length 3.50. Carapace 1.70 long, 1.40 wide. Abdomen 1.90 long, 1.30 wide. Clypeus 0.13 high. Eye sizes and interdistances: AME 0.10, ALE 0.08, PME 0.10, PLE 0.08, AME-AME 0.13, AME-ALE 0.25, PME-PME 0.10, PME-PLE 0.30, MOA length 0.28 with anterior width 0.30 and posterior width 0.28. Leg measurements: I 5.85 (1.80, 2.15, 1.35, 0.55), II 4.80 (1.50, 1.70, 1.10, 0.50), III 2.75 (0.85, 1.00, 0.55, 0.35), IV 4.10 (1.25, 1.45, 1.00, 0.40). Carapace yellow, cervical groove inconspicuous, cephalic protuberance short, narrower than AME diameter. Chelicerae yellow with 4 promarginal teeth and 4 retromarginal teeth. Endites, labium and sternum coloured as chelicerae. Sternum with dark setae. Legs yellow, without rings. Abdomen about 1.5 times longer than wide, covered with long setae anteriorly, dorsum greyish with dark bordered folium, medially with 4 pairs of white spots; ventre greyish.
Palp (Figs 11A, B View Figure 11 , 18B View Figure 18 ): median apophysis with lamella and 2 spurs prolaterally, retrolaterally slightly curled; embolus thin, slightly curved, longer than terminal apophysis in prolateral view; conductor curved to a tapered tip, guiding the embolus; terminal apophysis trapezoidal with translucent lamella in prolateral view, fused with embolus at base.
Female (paratype IZCAS-Ar41716, Figs 11E, F View Figure 11 , 12 View Figure 12 ). Total length 6.60. Carapace 2.00 long, 1.70 wide. Abdomen 5.40 long, 2.10 wide. Clypeus 0.08 high. Eye sizes and interdistances: AME 0.10, ALE 0.08, PME 0.10, PLE 0.05, AME-AME 0.13, AME-ALE 0.20, PME-PME 0.15, PME-PLE 0.25, MOA length 0.28 with anterior width 0.28 and posterior width 0.30. Leg measurements: I 7.10 (2.25, 2.70, 1.55, 0.60), II 5.80 (1.75, 2.20, 1.30, 0.55), III 3.20 (1.00, 1.15, 0.65, 0.40), IV 4.90 (1.50, 1.75, 1.15, 0.50). Habitus similar to that of male, but abdomen about 2.6 times longer than wide.
Epigyne (Fig. 12 View Figure 12 ) triangular, about 1.1 times wider than long; median plate strongly keeled; copulatory openings round; copulatory ducts long, directed medially from their origin, then turned to the lateral edge and twisted to connect to the spermathecae ventrally; spermathecae ovoid, separated from each other.
