Type material: Holotype: male, Mt. Diaoluo (18º41.445’N, 109º52.410’E), Hainan Island, China, 18 April 2009, Guo Tang leg. ( IZCAS). Paratypes: 1 male, Mt. Diaoluo (18º39.955’N, 109º55.811’E), Hainan Island, China, 15 April 2009, Guo Tang leg. ( IZCAS); 1 male, Mt. Limu (19º8.541’N, 109º43.233’E), Hainan Island, China, 15 August 2010, Jie Liu and Haiqing Ren leg. (HBU).
Etymology. The specific name is dedicated to Mr Guo Tang for his kind help on the spiders collection; noun (name) in genitive case.
Diagnosis. This new species is similar to R. pinangensis (Thorell, 1891) in having a simple RTA and pointed embolus end, but can be distinguished from it by the following characters: 1. Embolus of this new species arising in 10-o’clock-position on the tegulum (3-o’clock-position in R. pinangensis ); 2. Embolus without apophysis in this new species (with apophysis in R. pinangensis ); 3. Embolus tip of this new species short ( Figs 3 View FIGURES 3 A – C , 4B–E View FIGURES 4 A – E ), with less than one distal coil (with 1.1 distal coils in R. pinangensis ).
Description. Male (holotype): Measurements (in mm): PL 6.5, PW 6.8, AW 4.3, PH 2.2, OL 8.4, OW 4.5. Eyes: AME 0.42, ALE 0.38, PME 0.31, PLE 0.36, AME–AME 0.25, AME–ALE 0.46, PME–PME 0.55,PME– PLE 0.86, AME–PME 0.24, ALE–PLE 0.35, CH AME 0.22, CH ALE 0.21. Leg and palp measurements: Pp 8.7 (2.9, 1.2, 1.3, -, 3.3), I 35.7 (9.4, 3.4, 10.3, 9.9, 2.7), II 37.5 (10.3, 3.5, 10.8, 10.3, 2.6), III 23.2 (7.1, 2.6, 6.2, 5.3, 2.0), IV 28.8 (8.9, 2.4, 7.9, 7.4, 2.2). Leg formula: II-I-IV-III. Spination: Pp 131, 100, 1020; Fe I–III 323, IV 322; Pa I–III 101, IV 100; Ti I–IV 2226; Mt I–III 2024, IV 2026. Chelicerae with 3 anterior teeth and 4 posterior teeth, with the proximal tooth of the posterior cheliceral teeth being the largest. Color: Prosoma reddish brown, legs yellowish brown. Cephalic region and chelicerae darker. Opisthosoma yellow, dorsally with pattern of three dark longitudinal stripes ( Fig. 4A View FIGURES 4 A – E ).
Palp as in diagnosis. Embolus arising in a 10-o’clock-position on the tegulum, without embolic apophysis, with a distinct prolateral embolic indentation (EI in Figs. 3B View FIGURES 3 A – C , 4D View FIGURES 4 A – E ), with a short and pointed distal end. Sperm duct broad, almost U-shaped in a ventral view. RTA simple, apically tapered in lateral view. Cymbium distinctly longer than tibia ( Figs 3 View FIGURES 3 A – C , 4B–E View FIGURES 4 A – E ).
Female: Unknown.
Distribution. China (Hainan Island) ( Fig. 5 View FIGURE 5 ).
