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 AR00181). Paratypes: 3 males in two vials, same data as holotype; 1 female, 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 AR00182); 5 females in two vials, same data as previous.

Etymology. Latin cuspidatus (having a cusp), referring to the small lateral cusp on the front surface of the male chelicera.

Diagnosis. Male can be distinguished from other Parabathippus species by the cheliceral shape and dentition ( Figs 57–58 ), and the palpal shape ( Figs 55–56 ). Female is similar in the epigynal shape to Parabathippus shelfordi , but differs in the presence of foliate marking on the dorsal abdomen ( Fig. 54 ); the wider window of the epigynum ( Fig. 59 ), the shorter copulatory duct and the more round spermatheca ( Fig. 60 ).

Description. Male (holotype, UBC-SEM AR00181). Carapace length 3.2 (variation: 2.8–3.2, n=5); abdomen length 3.3. Chelicera ( Figs 57–58 ): dark red brown; elongate; promargin with three teeth, retromargin with one tooth and one mound (some specimens without this mound); front surface with a cusp laterally. Palp ( Figs 55–56 ): yellow brown to brown. Embolic disc almost round; embolus coiled for about a circle; retrolateral tibial apophysis finger-like. First tibia with three pairs of ventral macrosetae; first metatarsus with five ventral macrosetae (3–2 aligned). First and second legs with ventral fringes. Measurements of legs: I 7.4, II 6.3, III 8.2, IV 6.6. Color in alcohol ( Fig. 53 ): carapace dark red brown, posterior eyes with dark surroundings, with a short orange stripe behind eye area; abdomen gray brown without distinct marking; first two pairs of legs red brown, last two pairs yellow brown. Some male specimens lighter in color than holotype.

Female (paratype, UBC-SEM AR00182). Carapace length 2.6 (variation: 2.6–2.9, n=5); abdomen length 3.3. First tibia with three pairs of ventral macrosetae; first metatarsus with five ventral macrosetae (3–2 aligned). Measurements of legs: I 5.4, II 4.9, III 6.9, IV 5.7. Epigynum ( Fig. 59 ): median septum continuous with anterior margin of window. Vulva ( Fig. 60 ): copulatory duct partly membranous, anterior margin of copulatory duct loop far anterior to the anterior margin of window, with accessory gland on the sclerotized part of the copulatory duct; spermatheca oval. Color in alcohol ( Fig. 54 ): carapace light yellow, eye area orange, with two brownish stripes behind eye area; abdomen grayish brown, with a distinct yellowish foliate marking medially; legs light orange, with brownish markings.
