Type material. Holotype ♁, CHINA: Sichuan Province: Chengdu City, Chongzhou County, Wenjingjiang Town , Anzihe Conservation Area , Shaoyaogou Protection Station (30°47.577′N, 103°12.683′E, 1641 m a.s.l.), 2 Oct. 2016, leg. Yannan Mu. GoogleMaps

Paratypes: 2 ♁ 2 ♀, with same data as holotype; 2 GoogleMaps 6 ♀, same locality, Maliugou (30°46.790′N, 103°13.530′E, 1692 m a.s.l.), 3 Oct. 2016, leg. Luyu Wang. GoogleMaps

Etymology. The species name is derived from the type locality; noun in apposition.

Diagnosis. This new species resembles O. longituba Wang, Zhang & Zhang, 2012 in having a similar-shaped embolus, but can be recognized by: 1) the palmate-shaped retrolateral tibial apophysis (vs rectangular, cf. Fig. 47B View FIGURE 47 and fig. 5F in Wang et al. [2012]), 2) the closely situated copulatory openings (vs separated by about one spermatheca diameter, cf. Fig. 47E View FIGURE 47 and fig. 5H in Wang et al. [2012]), and 3) distinctly separated spermathecae (vs close to each other, cf. Fig. 47F View FIGURE 47 and fig. 5G in Wang et al. [2012]).

Coloration. Carapace yellow, radial striae distinct, beside fovea. Abdomen gray, with narrow dorsal scutum anteriorly, large black pattern beside dorsal scutum, four black transverse stripes at posterior of abdomen ( Fig. 46A, B View FIGURE 46 ). Legs yellow.

Palp as in Figs 47A–D View FIGURE 47 , 48A–C View FIGURE 48 . Femoral apophysis well developed, nearly at middle parts of femur. Tibia about half length of femur. Prolateral tibial apophysis distinct, triangular. Retrolateral tibial apophysis flat, palmate-shaped, tip blunt, curved towards cymbium. Tegulum nearly diamond-shaped; tegular apophysis small, semicircular. Sperm duct distinct, tapering from retrolateral side of tegulum to embolus. Embolus needle-like, transverse. Conductor absent.

Female (Paratype): total length 3.79, carapace 1.68 long, 1.44 wide; abdomen 2.11 long, 1.48 wide. Eye sizes and interdistances: AME 0.10, ALE 0.10, PME 0.08, PLE 0.09; AME–AME 0.04, AME–ALE 0.01, ALE–ALE 0.24, PME–PME 0.12, PME–PLE 0.07, PLE–PLE 0.42, ALE–PLE 0. 12. EAW 0.56, CRW 0.79, EAW/CRW 0.71, CRW/CW 0.55. MOA 0.28 long, anterior width 0.21, posterior width 0.30. CH 0.15, CH /AME 1.50. Labium 0.16 long, 0.25 wide. Sternum 0.97 long, 0.92 wide. Leg measurements: Ⅰ 6.35 (1.58, 0.66, 1.84, 1.53, 0.74), II 5.32 (1.40, 0.57, 1.35, 1.27, 0.73), III 4.62 (1.22, 0.52, 0.97, 1.21, 0.70), IV 6.78 (1.78, 0.64, 1.53, 1.86, 0.97).

Other characters as in male, except carapace darker and dorsal scutum absent ( Fig. 46C, D View FIGURE 46 ).

Epigyne as in Figs 47E–F View FIGURE 47 , 48D–E View FIGURE 48 . Epigynal plate sclerotized, with small depression centrally. Median septum absent. Copulatory openings oval, close to each other, located at centre of atrium. Copulatory ducts long, inverted V-shaped. Connecting tubes short, auriform. Bursa balloon-shaped, membranous. Spermathecae small, round, separated by about half their diameter. Fertilization ducts located at anterior margin of spermathecae.
