Parabathippus magnus sp. nov.

Figs 66–74 , 111–113

Type material. Holotype: male, MALAYSIA: PAHANG: Tanah Rata, Jungle Trail 9 from Robinson Falls, 4.46° N, 101.40° E, elev. 1200–1500 m, 21–22 May 2005, coll. W. Maddison, D. Li, I. Agnarsson, J. Zhang, WPM#05–035 (UBC-SEM AR00184). Paratypes: 1 female, same data as holotype (UBC-SEM AR00185); 4 males and 4 females in three vials, same data as holotype.

Etymology. Latin magnus (large), referring to the large second tooth-like protrusion on the promargin of the male chelicera.

Diagnosis. Could be distinguished from other Parabathippus species by the presence of large tooth-like protrusions near the fang base of the promargin, the absence of a lateral cusp on the front surface of the male chelicera ( Figs 70–71 ); the thick embolus of the male palp ( Figs 68–69 ); the presence of transverse ridges within the epigynal window, the wide median septum ( Fig. 73 ); and the irregular-shaped spermatheca ( Fig. 74 ).

Description. Male (holotype, UBC-SEM AR00184). Carapace length 3.2 (variation: 2.7–3.5, n=5); abdomen length 3.6. Chelicera ( Figs 70–71 ): yellow brown; elongate; promargin with four teeth with the second one from the fang base large, retromargin with two teeth. Palp ( Figs 68–69 ): yellow brown. Embolus thick and coiled for about one and a half circle; retrolateral sperm duct loop occupying about two thirds of bulb width; retrolateral tibial apophysis finger-like with a few cusps from ventral view. First tibia with three pairs of ventral macrosetae; first metatarsus with five ventral macrosetae (3–2 aligned). First leg with ventral fringes on tibia and patella. Measurements of legs: I 9.4, II 7.3, III 9.9, IV 8.1. Color in alcohol ( Fig. 66 ): carapace red brown, posterior eyes with dark surroundings; abdomen brown with indistinct yellowish speckles and a yellowish brown foliate marking medially; legs red brown to orange.

Female (paratype, UBC-SEM AR00185). Carapace length 2.7 (variation: 2.7–3.3, n=5); abdomen length 3.2. Chelicera ( Fig. 72 ): with two promarginal teeth and one retromarginal tooth. First tibia with three pairs of ventral macrosetae; first metatarsus with five ventral macrosetae (3–2 aligned). Measurements of legs: I 6.4, II 5.7, III 9.1, IV 6.6. Epigynum ( Fig. 73 ): median septum of window wide and short, not reaching anterior margin of the window; with transverse ridges within window. Vulva ( Fig. 74 ): most of copulatory duct membranous, only a short region before spermatheca well sclerotized; spermatheca irregular in shape. Color in alcohol ( Fig. 67 ): carapace light orange, eye area brownish, with two brownish stripes behind eye area; abdomen gray brown, with some yellowish streaks and speckles, and a big yellowish foliate marking medially; legs light orange.
