Etymology.
The specific name is a patronym in honour of the late Dr. Guo Tang for his contribution to the taxonomy of the spider family Thomisidae in China and he was one of the collectors of the type specimens; noun (name) in genitive case.
Diagnosis.
Eriovixia tangi sp. nov. resembles E. cavaleriei by having a similar abdominal pattern, but it can be distinguished from the latter by the following characters: 1) male palpal femur with large apophysis vs. absent; 2) kidney-shaped, long spermathecae vs. ovoid; and 3) terminal apophysis covered with small denticles vs. lacking denticles.
Description.
Male (holotype, Figs 5A-D View Figure 5 , 17C View Figure 17 , 19C View Figure 19 , 20C View Figure 20 ). Total length 4.10. Carapace 1.60 long, 1.60 wide. Abdomen 2.40 long, 1.80 wide. Clypeus 0.10 high. Eye sizes and interdistances: AME 0.10, ALE 0.08, PME 0.10, PLE 0.08, AME-AME 0.15, AME-ALE 0.23, PME-PME 0.15, PME-PLE 0.30, MOA length 0.33 with anterior width 0.33 and posterior width 0.30. Leg measurements: I 7.70 (2.50, 2.80, 1.75, 0.65), II 5.40 (1.75, 1.75, 1.30, 0.60), III 3.45 (1.20, 1.15, 0.65, 0.45), IV 4.85 (1.50, 1.65, 1.20, 0.50). Carapace yellow, darkened around fovea, with 2 long setae anteriorly, cervical groove inconspicuous, cephalic protuberance below wider than an AME diameter. Chelicerae, endites, labium and sternum yellow. Legs yellow, without rings. Abdomen about 1.2 times longer than wide, dorsum with a large, pale folium and a dark spot posteriorly; ventre greyish-yellow with a pair of white arcuate patches and 2 pairs of white spots around spinnerets.
Palp (Figs 5A, B View Figure 5 , 17C View Figure 17 ): with a large, distally expanded femoral apophysis; median apophysis slightly wider than bulb diameter in apical view, curled laterally; embolus small, square at base in prolateral view, covered with small denticles; terminal apophysis large, rounded, well sclerotised with dozens of fine denticles; conductor flat, about 3/5 width of bulb diameter in apical view.
Female (paratype IZCAS-Ar41665, Figs 5E, F View Figure 5 , 6 View Figure 6 ). Total length 6.50. Carapace 2.00 long, 1.60 wide. Abdomen 4.60 long, 3.30 wide. Clypeus 0.08 high. Eye sizes and interdistances: AME 0.13, ALE 0.10, PME 0.13, PLE 0.10, AME-AME 0.13, AME-ALE 0.23, PME-PME 0.15, PME-PLE 0.30, MOA length 0.30 with anterior width 0.30 and posterior width 0.30. Leg measurements: I 7.50 (2.50, 2.80, 1.55, 0.65), II 5.80 (1.95, 2.15, 1.10, 0.60), III 3.40 (1.15, 1.10, 0.70, 0.45), IV 4.95 (1.70, 1.80, 0.95, 0.50). Habitus similar to that of male, but cervical groove more conspicuous, cephalic region darker, sternum with a large pale spot posteriorly and abdomen droplet-shaped and more pointed posteriorly.
Epigyne (Fig. 6 View Figure 6 ) about 1.8 times longer than wide, triangular and tapering posteriorly, depressed anteriorly; copulatory openings close to tip of scape; copulatory ducts very long, touching each other at their origin, then turned dorsally and twisted near lateral edge, connected to spermathecae medially; spermathecae long, kidney shaped, posterior end larger than anterior end, touching each other posteriorly.
