Figs 10, 11, 21 Type material. Holotype ♂: China: Sichuan Province: Garze Tibetan Autonomous Prefecture: Luding County, the road from Moxi Town to Yajiageng, N29°46'31" , E102°03'34" , 2412 m, 10.X.2005, X. Zhang and X. Xu. Paratype: 1♀, same data as holotype. Etymology. The specific name refers to the type locality; adjective. Diagnosis. The male is similar to that of Sinocoelotes hehuaensis sp. n., but can be distinguished from it by the slenderer conductor, with the hook-like apex (conductor peg-shaped in Sinocoelotes hehuaensis sp. n.), the smaller dorsal conductor apophysis (about 1/2 width and 1/3 length of Sinocoelotes hehuaensis sp. n.) (cf. Figs 10 A-C and 7 A-C ). The female is similar to that of Sinocoelotes kangdingensis sp. n., but can be distinguished from it by the shape of atrium, anterior part wider than posterior part in Sinocoelotes ludingensis sp. n. (anterior part narrower than posterior part in Sinocoelotes kangdingensis sp. n.), the broader copulatory ducts, the longer (twice as long as Sinocoelotes kangdingensis sp. n.) and medially originating spermathecal heads (laterally originating in Sinocoelotes kangdingensis sp. n.) (cf. Figs 11 A-B and 9 A-B ). Figure 10. Male palp of Sinocoelotes ludingensis sp. n., holotype. A Prolateral B Ventral C Retrolateral. Scale bar: equal for A, B and C. Figure 11. Epigyne and habitus of Sinocoelotes ludingensis sp. n., holotype and paratype. A Epigyne, ventral B Vulva, dorsal C Male habitus, dorsal D Female habitus, dorsal E Female habitus, ventral. Scale bars: equal for D and E. Description. Male. Total length 7.12. Carapace 3.40 long, 2.40 wide. Abdomen 3.72 long, 2.20 wide. Eye sizes and interdistances: AME 0.14, ALE 0.20, PME 0.19, PLE 0.16 ; AME-AME 0.09, AME-ALE 0.03, PME-PME 0.09, PME-PLE 0.12. Leg measurements: I 11.04 (3.08, 3.48, 2.80, 1.68); II 9.66 (2.82, 3.13, 2.23, 1.48); III 8.82 (2.60 2.50, 2.47, 1.25); IV 12.19 (3.36, 3.76, 3.48, 1.59). Chelicerae with four retromarginal teeth. Palp: patellar apophysis short, about 1/2 of patella; RTA broad and long, subequal to the length of tibia; LTA short, less than 1/6 length of RTA; cymbial furrow short, about 1/5 length of cymbium; conductor long, slender, and apex hook-like; median apophysis spoon-like; dorsal conductor apophysis broad, the visible part (between conductor and tegulum) finger-like; embolus beginning at seven o'clock position (Fig. 10 A-C ). Female. Total length 6.76. Carapace 3.44 long, 2.36 wide. Abdomen 3.32 long, 2.00 wide. Eye sizes and interdistances: AME 0.14, ALE 0.21, PME 0.14, PLE 0.16; AME-AME 0.09, AME-ALE 0.04, PME-PME 0.13, PME-PLE 0.16. Leg measurements: I 8.90 (2.52, 2.95, 2.08, 1.35); II 7.81 (2.28, 2.50, 1.81, 1.22); III 7.16 (2.03, 2.31, 1.84, 0.98); IV 9.66 (2.69, 3.06, 2.66, 1.25). Chelicerae as in male. Epigyne: atrium, trapezoidal, occupying 1/4 of epigynal plate square, narrowing at the posterior part; teeth long, located anterior-laterally, subequal to the atrial length; copulatory ducts membranous, semitransparent, parallel to each other, wider than basal part of spermathecae; spermathecae separated from each other by spermathecal heads' width, basal part of spermathecae about 1/2 thinner than anterior part; spermathecal heads long, located at mid-anterior of spermathecae (Fig. 11 A-B ). Distribution. Known only from the type locality (Fig. 21).
