Jäger leg. 28.VI.2004 . Etymology. This species is named for Shuqiang Li from Beijing , honouring his enormous contributions to arachnological knowledge in China ; name in apposition. Diagnosis. Medium-sized Ctenidae (total length female 13.0). Distinguished from other Ctenus spp. by the acute epigynal teeth and by the two bulging areas of the epigynal plate close to the teeth ( Figs 138–139 ). FIGURES 138–141.

Chelicerae with 3 promarginal, 4 retromarginal teeth, and with c. 14 denticles most of them in patch close to promarginal teeth. Retromargin of chelicerae close to fang base with 8–9 thin bristles. Leg claw I with 1(2), leg claw II with 2, leg claws III–IV with 3 secondary teeth. Position of tarsal organ: I 0.80, II 0.79, III 0.62, IV 0.60. Copulatory organ as in diagnosis ( Figs 138–141 ). Epigynal field wider than long, with two anterio-lateral patches fused with field, with one pair of slit sense organs anterio-laterally. Median plate anteriorly narrow, widening gradually and not narrowing posteriorly (as for instance in C. theodorianum spec. nov. ); lateral teeth arising at anterior part, pointing posterio-medially. Internal duct system with lateral folds diverging posteriorly. Spermathecae directed towards each other, widened medially, separated by less of their diameter, internally with a relatively large transverse oval chamber between spermathecae and fertilisation ducts, the latter acuminate and pointing medially. Colour ( Figs 142–143 ). Reddish-brown with slightly darker pattern. Dorsal shield of prosoma with characteristic slightly lighter median band, widened behind eyes, constricted behind distinctly marked fovea.
