Figs 1–2

Type material. Holotype ♂, China, Fujian Province, Wuyi Mountain National Natural Reserve (27°42′N, 118°0′E), Moshikeng (27°59′N, 118°13′E), 4 June 2013, leg. Chi Jin.

Paratypes: 3♂ and 1♀, same data as for holotype; 1♀, Nankeng (27°44′N, 117°41′E), 12 July 2011, leg. Feng Zhang; 1♀, Tianlai (27°44′N, 118°01′E), 7 August 2010, leg. Feng Zhang; 1♀, Tongmu Village (27°45′N, 117°40′E), 8 June 2013, leg. Chi Jin.

Etymology. The species name is derived from the type locality; adjective.

Diagnosis. The male of this new species resembles O. bawangling Fu, Zhang & Zhu, 2010 in having tufted hairs on the distal part of cymbium ventrally around the embolus tip and by having a similar RTA, but can be distinguished from it by: 1) dorsal scutum of abdomen wider and longer than that of O. bawangling ; 2) TA shorter and not extending outside the distal margin of the tegulum; and 3) RTA longer than that of O. bawangling (see Fu et al. 2010: 645: figs 3A–F). The female is similar to O. limushan Fu, Zhang & Zhu, 2010 in having a wide epigynal median plate, but can be distinguished from the latter by: 1) the thicker CD; 2) kidney-shaped, not pearshaped, bursae; and 3) spermathecae posteriorly much closer to each other ( Fu et al. 2010: 648: figs 4A–C). The new species is also similar to O. jianfengling Fu, Zhang & Zhu, 2010 in having a wider and longer abdominal scutum, but differs from the latter by: 1) the longer RTA; 2) kidney-shaped bursae; and 3) spermathecae posteriorly much closer to each other ( Fu et al. 2010: 645: figs 1A–H, 2A–E).

Description. Male ( Fig. 1 A). Total length 3.45–3.72 (n=4). Holotype: body 3.72 long; carapace 1.75 long, 1.51 wide; abdomen 1.91 long, 1.10 wide. Carapace light brown, oval, abruptly narrow anteriorly; thoracic part slightly higher than the cephalic part; fovea longitudinal, distinct. In dorsal view, AER slightly recurved, PER slightly wider than AER and almost straight. Diameter of eyes: AME 0.14, ALE 0.13, PME 0.09, PLE 0.12. Interdistances of eyes: AME–AME 0.05, AME–ALE 0.03, PME–PME 0.13, PME–PLE 0.05. MOA 0.31 long, front 0.27 wide, back 0.31 wide. Clypeus 0.10 high. Chelicerae with strong, paired anterior spines; cheliceral promargin with three well-separated teeth and retromargin with five clustered denticles. Labium wider than long. Legs light brown. Leg measurements: leg I 9.00 (2.22, 0.61, 2.55, 2.12, 1.50), II 7.17 (1.82, 0.59, 1.94, 1.67, 1.15), III 5.98 (1.52, 0.54, 1.38, 1.64, 0.90), IV 9.28 (2.44, 0.58, 2.21, 2.68, 1.37). Leg formula: 4123. Femora I–IV basally with one dorsal spine. Femur I with five prolateral spines; tibia I with nine pairs of ventral spines, tibia II with seven pairs of ventral spines, tibia III distally with one pair of ventral spines; metatarsi I–II with four pairs of ventral spines, metatarsi III and IV with distal preening brush. Abdomen oval, grey; anterior half with a wide dorsal scutum; posterior half dark brown, with several chevron-like stripes dorsally. Colulus absent, few hairs in its position.

Palp ( Figs 1 B–D, 2A–B). Palp with single, long RTA extending posteriorly, with the tip bending towards the cymbium; cymbium ventrally with tufted hairs on the distal part; femur distally with an apophysis and concavity on retrolateral side; tegulum convex, TA small and short, retrolateral and not extending beyond the margin of tegulum; embolus hook-shaped, sharp apically.

Female ( Fig. 1 E). Total length 4.20–5.01 (n=4). One paratype from Moshikeng: body 5.01 long; carapace 1.85 long, 1.68 wide; abdomen 2.94 long, 1.68 wide. Carapace light brown, oval, abruptly narrow anteriorly. Diameter of eyes: AME 0.12, ALE 0.11, PME 0.09, PLE 0.10. Eye interdistances: AME–AME 0.06, AME–ALE 0.04, PME–PME 0.13, PME–PLE 0.06. MOA 0.30 long, front 0.27 wide, back 0.31 wide. Clypeus 0.11 high. Chelicerae light brown. Labium and gnathocoxae yellowish brown. Legs and palps yellowish brown. Leg measurements: I 8.87 (2.24, 0.71, 2.66, 1.88, 1.38), II 7.33 (1.78, 0.67, 2.07, 1.59, 1.22), III 5.94 (1.56, 0.53, 1.24, 1.62, 0.99), IV 9.21 (2.43, 0.65, 2.16, 2.65, 1.32). Leg formula: 4123. Femora I–IV basally with one dorsal spine. Femur I with five prolateral spines and femur II with three prolateral spines; tibia I with nine pairs of ventral spines, tibia II with eight pairs of ventral spines, tibia III distally with one pair of ventral spines; metatarsus I with four pairs of ventral spines, metatarsus II with three pairs of ventral spines, metatarsi III and IV with distal preening brush. Abdomen without dorsal scutum. Other characters as in male.

Epigyne ( Figs 1 F–G, 2C–D): median plate wide, with sclerotized “bubbles” (as per Jäger & Wunderlich 2012: figs 28–30, who view these as remnants of fused furrows), CO connecting with bursa anteriorly and CD posteriorly in ventral view. Vulva anteriorly with a pair of large transparent kidney-shaped bursae; posteriorly with a pair of slender spermathecae, near to each other posteriorly; copulatory ducts relatively long.

Distribution. Known only from eastern China ( Fig. 6 ).
