W. Maddison & Luc Fimo Tuki, WPM#08-019 ; 1 female, same data as previous .

Etymology. Latin extranea (strange), referring to the peculiar male palpal structure.

Diagnosis. Male chelicerae ( Figs 57–58) are not as elongate as those of C. forceps (Doleschall) (see Prószyṅski 1984, 1987) and C. hinnulea (Thorell) (see Davies & Żabka 1989). Also differs from other species by the presence of dark markings in the eye area of male and female ( Figs 48–53), the big and bowl-like embolic disc and the presence of proximal tegular lobe of the male palp ( Figs 54–56), and the narrow and convoluted copulatory duct of the vulva ( Fig. 61).

Description. Male (holotype, UBC-SEM AR00084). Carapace length 2.1 (variation 2.1–2.7, n=2); abdomen length 2.2. Chelicera ( Figs 57–58): yellow brown; not very elongate; with two promarginal teeth and one long bicuspid tooth on retromargin (the paratype male with one big dagger-like retromarginal tooth). Palp ( Figs 54–56): yellow brown. Cymbial distal groove more retrolateral. Proximal tegular lobe present. Embolic disc large and bowl-like. Retrolateral tibial apophysis finger-like with distal end hooked from ventral view. Femur of palp slightly curved. Measurements of legs: I 4.2, II 3.7, III 4.6, IV 4.1. Color in alcohol ( Fig. 52): carapace light orange, with dark markings in eye area; abdomen anterior end light yellow, other part dark; legs light red brown to light yellow.

Female (paratype, UBC-SEM AR00085). Carapace length 2.3 (variation 2.2–2.3, n=3); abdomen length 2.9. Chelicera ( Fig. 59): yellowish. Measurements of legs: I 3.4, II 3.5, III 4.1, IV 3.7. Epigynum ( Figs 60–61): median septum relatively narrow; opening to the copulatory duct at posterior margin of window. Copulatory duct long and convoluted; spermatheca small and oval. Color in alcohol ( Fig. 53): carapace light yellow, also with dark markings within eye area; abdomen yellowish, without distinct dark markings, legs light yellow. Body green when alive ( Figs 50–51)

Natural history. Specimens were found beating vegetation in forest edge and disturbed forest.
