Diagnosis: This species resembles C. thailandensis in having the short, laterally arising epigynal teeth, similar atrium, anteriorly extending copulatory ducts and similar palp, but can be distinguished by the distinctly extending, folding copulatory ducts (as long as spermathecal length), strongly pointed distal end of patellar apophysis, and long, slender conductor which is longer than its dorsal apophysis ( Figs 49–57 ).

Description: Female (one of CASENT9020441 measured): Large sized coelotine, total length 12.50 ( Fig. 63 ). Eyes subequal in size, with lateral eyes slightly larger than median eyes (AME 0.19, ALE 0.24, PME 0.19, PLE 0.21); anterior eyes equally separated by slightly more than half of their diameter; PME separated from each other by slightly less than their diameter, from PLE by more than PME diameter (AME-AME 0.11, AME-ALE 0.11, PME-PME 0.16, PME-PLE 0.28, AME-PME 0.22) ( Fig. 64 ). Chelicerae with 3 promarginal and 4 retromarginal teeth. Labium longer than wide (L/W=1.20) ( Fig. 65 ). Epigynal teeth short, arise anteriorly lateral to atrium, separated by more than atrial width; atrium small, with distinct, continuous anterior margin but indistinct lateral margins; copulatory ducts broad, extending anteriorly approximately the length of spermathecae, more or less folded longitudially; spermathecae with small bases and broad stalks; spermathecal heads arise distally from lateral side of spermathecae ( Figs 49–54 , 58–59 , 69–70 , 74–87 ).

Male (one of CASENT9020441 measured): Large sized coelotine, total length 12.00 ( Fig. 66 ). Eyes subequal in size, with lateral eyes slightly larger than median eyes (AME 0.19, ALE 0.22, PME 0.21, PLE 0.22); AME separated from each other by 2/3 of their diameter, from ALE by about ½ of AME diameter; PME separated from each other by slightly less than their diameter, widely separated from PLE by more than PME diameter (AME-AME 0.13, AME-ALE 0.08, PME-PME 0.18, PME-PLE 0.27, AME-PME 0.24) ( Fig. 67 ). Chelicera with 3 promarginal and 4 retromarginal teeth. Labium longer than wide (L/W=1.21) ( Fig. 68 ). Palpal patellar apophysis large, slightly extending and pointing distally; RTA more than half of tibial length, with distinctly protruding distal end; lateral tibial apophysis broad; cymbial furrow short, less than 1/3 of cymbial length; conductor slender, with a dorsal apophysis, a small basal lamella; median apophysis broad, round, spoon-shaped; embolus short, filiform, prolateral in origin ( Figs 55–57 , 60–62 , 71–73 ).

Notes: Female epigynal teeth vary slightly in length but are consistently arising anteriorly lateral to atrium, slightly posterior of anterior atrial margin, widely separated by slightly more than atrial width. Atrium also varies in size and shape from having a wide to a narrow anterior atrial margin. Copulatory ducts are consistently long, extending anteriorly, slightly folding longitudially but may vary in size and shape. Considering the variation in epigynal teeth, atrium, copulatory ducts and the different shapes of spermathecae, in addition to the widespread occurrence, there might be more than one species involved but the lack of sufficient male and female specimens from additional localities prevents us from making a more detailed hypothesis.

Distribution: China (Yunnan) ( Fig. 155 ).
