Colyttus robustus sp. nov.

Figs 10–12 , 106

Type material. Holotype: male, MALAYSIA: PAHANG: Genting Highlands, 3.400° N, 101.777° E, elev. 1000 m, 15–16 May 2005, coll. W. Maddison, D. Li, I. Agnarsson, J. Zhang, WPM#05–023 (UBC-SEM AR00170).

Etymology. Latin robustus (robust), referring to the shape of the body of the species.

Diagnosis. Differs from Colyttus bilineatus Thorell (see Prószyński 1987) in the absence of dark stripes on the abdomen ( Fig. 10 ), the wider male palpal bulb, the larger embolic disc, the shape of the embolus and the wider proximal tegular lobe of the male palp ( Figs 11–12 ). Differs from C. lehtineni Żabka, 1985 in the absence of apophysis besides the embolus and the shorter retrolateral tibial apophysis of the male palp ( Figs 11–12 ).

Description. Male (holotype, UBC-SEM AR00170). Carapace length 3.2; abdomen length 3.8. Chelicera: promargin with two teeth, retromargin with one tooth. Palp ( Figs 11–12 ): light yellow to light yellow brown. Proximal tegular lobe obvious; embolus short and relatively thick; retrolateral tibial apophysis finger-like. First tibia with three pairs of ventral macrosetae; first metatarsus with two pairs of macrosetae. Ventral patella, tibia and metatarsus of leg I with fringes. Measurements of legs: I 7.3, II 6.3, III 7.1, IV 6.9. Color in alcohol ( Fig. 10 ): eye area orange, other part light orange, with a wide light yellow stripe behind fovea; abdomen light brown, with a large sandy yellow foliage-like marking medially and a brown spot on each side of the foliage-like marking near the center; legs light yellow to dark brown with first pair darker in color.

Female. Unknown.
