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.
