( N21º54.498' , E101º16.326' , 586 m ), 17 July 2007 , leg. G. Zheng (Fogging-XZII) . Etymology. The species epithet is a Latin adjective and refers to the spoon-shaped embolus. Diagnosis. This new species can be easily distinguished from those of all other species of the C. corticalis group by the strong, spoon-shaped embolus ( Figs 1A , C–D). Description.

Prosoma ( Figs 2 A–C) pyriform, ocular region distinctly narrowed, widest between coxae II and III; in profile highest just behind longitudinal fovea; integument smooth, clothed with short fine hairs. Carapace red brown, without distinct color pattern; fovea dark. Chelicerae protruding and coloured as carapace, with three promarginal and two retromarginal teeth. Labium and endites dark brown, longer than wide. Sternum brown. Eyes: AER slightly recurved, PER wider than AER and slightly procurved in dorsal view. AME dark, other eyes light; with black rings.
