Figs 53–60, 108–110

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.
