Diagnosis. This species is easy to distinguish by the structure of copulatory organs.The male palp has a characteristic large bump on the retrolateral surface of the tibia, below the apophysis ( Figs 81, 83 View FIGURES 80–86 ). The copulatory openings are placed anteriorly in the epigyne, with copulatory ducts that are shaped like a question mark ( Figs 90–92 View FIGURES 87–92 ).

Redescription. Male. Measurements. Cephalothorax: length 2.4–3.5, width 1.7–2.6, height 1.2–1.8. Eye field: length 1.2–1.6, anterior width 1.7–2.3, posterior width 1.5–2.1. Abdomen: length 2.6–3.3, width 1.1–2.0. General appearance as in Figs 76, 77 View FIGURES 76–79 .Carapace high,convex,posterior surface sloping.Eyes large(especially anterior medians). Rings surrounding eyes black, carapace yellowish-orange to light brown, with lighter foveal area. Few bristles near eyes, some delicate brownish and whitish hairs on carapace slopes. Fovea poorly visible. Clypeus low, brown, naked. Sternum and mouthparts light yellow to brown. Chelicerae robust, with two small promarginal teeth, single large retromarginal tooth and short fang ( Fig. 80 View FIGURES 80–86 ). Abdomen small, narrower than carapace, oval, yellowish-beige, with ill-defined darker patches; in fresh specimens dark, greyish-brown or black, venter light yellow to dark brown. Some long brown bristles at anterior edge of abdomen. Spinnerets yellowish-grey. Legs cream or yellow, only tarsus and distal part of metatarsus of first leg brownish. First pair of legs longer than others. Patella I with single prolateral spine, tibia with four pairs of long ventral spines and 1-1 on retrolateral side, metatarsus with three pairs on ventral surface, 0-1 on pro- and retrolateral and two dorso-apical spines. Ventral spines very long. Leg hairs light. Pedipalp dark brown, its structure as in Figs 81–86 View FIGURES 80–86 . Tibial apophysis short, with a lobate enlargement below its base ( Figs 81, 83, 84 View FIGURES 80–86 ), bulb oval, tuft of long bristles on tibia prolaterally ( Fig. 81 View FIGURES 80–86 ). Length of legs and size of chelicerae varying in different specimens.

Female. Measurements. Cephalothorax: length 2.0–2.2, width 1.4–1.7, height 1.0–1.1. Eye field: length 1.0– 1.1, anterior width 1.3–1.4, posterior width 1.1–1.3.

Spination of distal segments of leg I as in male. Pedipalp with single long retrolateral spine on terminal segment. Epigyne weakly sclerotized, with large posterior pocket ( Figs 87–89 View FIGURES 87–92 ). Internal structure as in Figs 90–92 View FIGURES 87–92 , seminal ducts membranous, question markshaped, forming broad loop in initial part.
