Sinocoelotes songae (Liu, Li & Pham, 2010) comb. nov. Figs 1–3 Coelotes songae Liu, Li & Pham 2010: 24, figs 20A–B, 21A–B, 22A–B, 23A–B (♂ holotype from Tam Dao National Park, Vietnam; deposited in the Institute of Zoology, Chinese Academy of Sciences, unexamined). Material examined. 1♂ (VNMN-ARA-AGE-05) and 1♀ (VNMN-ARA-AGE-09): VIETNAM, Vinh Phuc Province: Tam Dao National Park, 21.4720°N, 105.6364°E, 1023m, 10 Dec. 2019, Q. D. Hoang leg. Diagnosis. Males of Sinocoelotes songae comb. nov. are similar to that of S. pseudoterrestris (Schenkel, 1963) but can be distinguished by: bifurcated conductor in S. songae comb. nov. (Fig. 1C, and figs 20B, 22B in Liu et al. 2010) (pointed in S. pseudoterrestris, see fig. 129 in Wang 2002), conductor dorsal apophysis wide and blunt (Fig. 1C–D and figs 21A, 22B in Liu et al. 2010; pointed in S. pseudoterrestris, see figs 129–130 in Wang 2002). Female resembles S. ludingensis Zhao & Li, 2016 and S. yanhengmei (Wang, Griswold & Ubick, 2009), but differs from the latter by epigynal teeth positioned posteriorly (Fig. 2A) (anteriorly in S. ludingensis, see fig.11A in Chen et al. 2016), copulatory ducts widely spaced and short about a half spermathecae (Fig. 2B) (more closely and long about 2/ 3 in both S. ludingensis and S. yanhengmei), spermathecal heads directed laterally (Fig. 2B; anteriad in both S. ludingensis and S. yanhengmei). Description. Male (Figs 1A, C–D), see Liu et al. (2010). Female (Figs 1B, 2A–B). Total length 12.66, prosoma 6.20 long, 3.93 wide; opisthosoma 6.46 long, 4.08 wide. Eye measurements: AME 0.26; ALE 0.24; PME 0.22; PLE 0.23; AME– AME 0.08; AME–ALE 0.09; ALE–PLE 0.12; PME–PME 0.16; PME–PLE 0.30. Clypeus height 0.33. Leg formula: IV, I, II, III; leg measurements: I: 16.51 (4.31, 5.66, 4.06, 2.48); II: 14.88 (4.01, 4.98, 3.72, 2.17); III: 14.20 (3.90, 4.50, 3.88, 1.92); IV: 18.46 (4.89, 5.87, 5.41, 2.29). Chelicerae with three promarginal and four retromarginal teeth. Epigynal teeth long, blunt, situated posteriorly (Fig. 2A); atrium large, occupying almost the length of epigyne, anterior part wider than posterior, with copulatory openings located antero-laterally (Fig. 2A); copulatory ducts far away from each other and narrow at the anterior (Fig. 2B); spermathecal heads horizontal, directed laterally (Fig. 2B); spermathecae simple and meandering (Fig. 2B). Distribution. Vietnam (Vinh Phuc Province). Remark: Although there is already a species in the genus Sinocoelotes named S. songi, S. songae and S. songi are different species, hence no taxonomy or naming problem arises.
