Diagnosis. The species is distinctive in having a unique form of the copulatory organs. The male can be recognized by the short palpal tibial apophysis, overlain by a characteristic tuft of very long and dense bristles ( Fig. 7 View FIGURES 6–12 ) and by the characteristic functional ‘conductor’ accompanying the embolus ( Fig. 9 View FIGURES 6–12 ). The epigyne has a strongly sclerotized posterior rim and semi-circular hoods above the copulatory openings ( Fig. 11 View FIGURES 6–12 ).

Etymology. The specific name is Latin, meaning orange, and refers to the abdominal colouration of the female of this species.

Description. Male. Measurements. Cephalothorax: length 2.0–2.8, width 1.6–2.1, height 1.0–1.4. Eye field: length 1.0–1.4, anterior width 1.5–1.9, posterior width 1.4–1.8. Abdomen: 1.9–2.4, width 1.0–1.3. General appearance as in Fig. 1 View FIGURES 1–5 . Carapace high, dark yellow to light brown, lateral slopes darker (clothed in brown hairs). Eyes surrounded by black rings, anterior eyes encircled by bright orange scales from above and white from below. White hairs form median light streak on thoracic part. Mouthparts light brown, sternum yellowish, chelicerae unidentate, fang short. Abdomen narrow, yellowish, with pattern composed by small dark marks placed on sides, marks larger and denser posteriorly. Long bristles at anterior edge of abdomen. Venter and spinnerets light yellow. Legs long, yellow, only femora brown. First pair longest, patella I with one spine on both lateral sides, tibia with four and metatarsus with three pairs of long ventral spines, additionally 1-1 shorter spines on both lateral surfaces of these segments ( Fig. 3 View FIGURES 1–5 ). Spines and leg hairs brown. Palps clothed in dark hairs. Palpal organ as in Figs 4–10 View FIGURES 1–5 View FIGURES 6–12 , bulb oval, embolus short, with accompanying membranous outgrowth, a functional conductor, which is terminal process of prolateral bulb edge. Tibial apophysis short and wide ( Figs 6, 10 View FIGURES 6–12 ), enveloped by very dense and long bristles, completely obscuring it from retrolateral side ( Figs 5 View FIGURES 1–5 , 7 View FIGURES 6–12 ).

Female. Measurements. Cephalothorax: length 1.8–2.0, width 1.4–1.6, height 1.0–1.1. Eye field: length 0.8– 1.0, anterior width 1.2–1.3, posterior width 1.1–1.2. Abdomen: length 1.8–2.2, width 1.1–1.6. General appearance as in Fig. 2 View FIGURES 1–5 . Slightly smaller than male. Carapace colouration as in male, with some white hairs on slopes. Anterior eyes encircled by white scales from below. Abdominal dorsum covered with black and orange reddish patches (bright patches placed laterally, Fig. 2 View FIGURES 1–5 ). In some specimens, abdomen dark brownish with irregular lighter median band, yellow in anterior part and reddish posteriorly. Venter dark grey with four lines composed of light dots. Black patches at base of spinnerets. Legs yellow, with brown femora, other segments with dark marks. Palp with single retrolateral spine on tarsus. Epigyne strongly sclerotized (especially posterior edge, with heart-shaped central depression ( Fig. 11 View FIGURES 6–12 ). Internal structure as in Fig. 12 View FIGURES 6–12 , copulatory openings hidden by sclerotized hoods, seminal ducts short and diverging, spermathecae spherical, thick-walled.
