Etymology: The specific name refers to its similarity to C. yunnanensis .

Diagnosis: The female resembles C. yunnanensis in having a similar vulva but can be distinguished by the anteriorly originating epigynal teeth and small, laterally extending copulatory ducts ( Figs 88–89 ). The male can be recognized by the broad conductor ( Figs 90–91 ).

Description: Male (holotype): Medium sized coelotine, total length 6.70 ( Fig. 97 ). Carapace 3.50 long, 3.20 wide. Abdomen 3.20 long, 2.00 wide. AME smallest, ¾ the size of other eyes which are subequal or with ALE slightly larger (AME 0.16, ALE 0.20, PME 0.18, PLE 0.19); AME separated by half of their diameter, from ALE by 1/3 of AME diameter; PME separated by slightly more than half of their diameter, from PLE by slightly more than PME diameter (AME-AME 0.07, AME-ALE 0.05, PME-PME 0.10, PME-PLE 0.18, AME-PME 0.13) ( Fig. 98 ). Promargin of chelicera with 3 teeth, retromargin 3. Labium slightly wider than long (L/W=0.96) ( Fig. 99 ). Palpal patellar apophysis short, broad, distinctly extending and pointing distally; RTA more than half of tibial length, distinctly extending distally; lateral tibial apophysis broad, distinctly separated from RTA; cymbial furrow short, less than half of cymbial length; conductor short, broad, somewhat twisted, with a dorsal apophysis, a small basal lamella; median apophysis broad, round, spoonshaped; embolus short, filiform, originating prolaterally ( Figs 90–91 , 94–96 ).

Female (one of the paratypes measured): Medium sized coelotine, total length 7.70 ( Fig. 100 ). Carapace 3.50 long, 2.20 wide. Abdomen 4.20 long, 2.80 wide. AME smallest, ¾ size of lateral eyes which are subequal; PME slightly larger than AME (AME 0.13, ALE 0.17, PME 0.15, PLE 0.17); anterior eyes equally separated by half of AME diameter; PME separated from each other by 2/3 of their diameter, from PLE by slightly more than PME diameter (AME-AME 0.06, AME-ALE 0.05, PME-PME 0.10, PME-PLE 0.17, AME-PME 0.16) ( Fig. 101 ). Promargin of chelicera with 3 teeth, retromargin 3. Labium slightly longer than wide (L/W=1.05) ( Fig. 102 ). Epigynal teeth short, arise anteriorly at atrium, separated by atrial width; atrium small, with distinct, continuous anterior margin but indistinct lateral margins; copulatory ducts small, slightly extending laterally; spermathecae broad, slightly separated, slightly extending anteriorly; spermathecal heads arising anteriorly from subdistal spermathecae ( Figs 88–89 , 92–93 , 103–108 ).

Distribution: China (Yunnan) ( Fig. 156 ).
