Canama triramosa sp. nov. 77–79 male holotype; 80 female paratype. FIGURES 77–80 are copyright © 2012 W. P. Maddison, released under a Creative Commons Attribution (CC–BY) 3.0 license. Etymology. The specific epithet is from the combination of the prefix tri- (three) and the Latin ramosa (branched), and refers to the large three-forked tooth on the promargin of male chelicerae. Diagnosis. Differs from other species by the unique three-branched promarginal tooth and the one large and wide retromarginal tooth on the male chelicera ( Figs 86–87 ). Similar in male palpal structure to Canama forceps (Doleschall) (see Prószyṅski 1984, 1987), but can be easily distinguished by the shorter and wider male chelicera ( Figs 86–87 ), the tooth pattern on the male chelicera ( Figs 86–87 ), the wider palpal bulb and the shape of the retrolateral tibial apophysis of the male palp ( Figs 83–85 ). Female is similar to C. extranea , but differs in the absence of dark markings in the eye area ( Figs 80 , 82 ), the thicker and less convoluted copulatory duct of the vulva ( Fig. 90 ).

Canama triramosa sp. nov. 81 male holotype, dorsal view; 82 female paratype, dorsal view; 83 male left palp, ventral view; 84 male left palp, retrolateral view; 85 male left palp (with patella and femur), retrolateral view; 86 male left chelicera, front view; 87 male left chelicera, back view; 88 female left chelicera, back view; 89 epigynum, ventral view; 90 cleared epigynum, dorsal view. Scale bars: 81–82, 1.0 mm; 83–88, 0.2 mm; 89–90, 0.1 mm. Description. Male ( holotype , UBC-SEM AR00088). Carapace length 2.1; abdomen length 2.5. Chelicera ( Figs 86–87 ): yellow brown; robust with a tri-forked big tooth on promargin and an axe-like tooth on retromargin. Palp ( Figs 83–85 ): yellowish to brownish. Cymbial distal groove more retrolateral. Proximal tegular lobe absent. Embolus long and coiled for about two circles. Retrolateral tibial apophysis finger-like. Femur of palp curved. Tibia of first leg with three pairs of ventral macrosetae; metatarsus with two pairs. Measurements of legs: I 6.5, II 5.1, III 5.6, IV 4.8. Color in alcohol ( Fig. 81 ): carapace yellowish, eye area light orange; abdomen grayish without distinct markings; legs light yellow with yellow brown annuli. Body more greenish when alive ( Figs 77–79 ). Female ( paratype , UBC-SEM AR00089). Carapace length 2.0 (variation 2.0–2.2, n=3); abdomen length 3.2. Chelicera ( Fig. 88 ): with a long bicuspid retromarginal tooth. Tibia of first leg with three pairs of ventral macrosetae; metatarsus with two pairs. Measurements of legs: I 4.2, II 3.7, III 4.7, IV 4.4. Epigynum ( Figs 89–90 ): window with a narrow median septum; opening at posterior end of window close to median septum. Copulatory duct long and convoluted with a gland-like process near the beginning. Color in alcohol ( Fig. 82 ): similar to that of male, but eye area of carapace yellow, abdomen orange with symmetrical gray markings. Body more greenish when alive ( Fig. 80 ).
