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 View FIGURE 1 , C–D).

Description. Male (holotype): Total length 7.34; prosoma 3.29 long, 2.31 wide; opisthosoma 3.59 long, 1.91 wide. Prosoma ( Figs 2 View FIGURE 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. Eye sizes and interdistances: AME 0.14, ALE 0.17, PME 0.14, PLE 0.16, AME–AME 0.11, AME–ALE 0.08, PME– PME 0.33, PME–PLE 0.18, MOQL 0.28, MOQA 0.41, MOQP 0.63. Legs brown, without distinct color markings. Leg formula: IV, II, I, III; leg measurements: I 7.78 (2.30, 3.38, 1.54, 0.96), II 9.29 (2.61, 3.85, 1.87, 1.05), III 7.43 (2.16, 2.47, 1.90, 0.69), IV 9.99 (2.81, 3.42, 2.82, 0.95). Opisthosoma ( Figs 2 View FIGURE 2 A–C) elongate-oval, dorsal scutum ovoid, lightly sclerotized, furnished with a thick tuft of hairs anteriorly; dorsum brown, without distinct color pattern; venter gray. Spinnerets brown. Palp ( Figs 1 View FIGURE 1 A–E): Tibia short, with two apophyses, VTA large and blunt, with partly membranous tip, thumb-like; RTA dark and strong, triangular, sharply pointed; bulb elongate-oval, strongly bulged and prolapsed, sperm duct indistinct in ventral view; embolus distinctly strong, with a expand and torsional tip, spoon-shaped, the embolic base situated prolateral on the tegulum; conductor membranous and blade-shaped, long, with blunt tip.

Female: Unknown.
