Diagnosis. The male is distinctive and characterised by the pedipalp structure which has a very long tibia with the apophysis placed dorsally, a rounded bulb without a proximal lobe and a small embolus with accompanying thin terminal apophysis. The seminal ducts of female epigynum are short and broad, the accessory glands are large and placed in the walls of the spermathecae.

Etymology. The specific name is Latin for strange, referring to the unique structure of the male pedipalp.

Description. Measurements (male/female). Cephalothorax: length 3.3/3.1–3.5, width 2.4/2.4–2.5, height 1.5/ 1.4. Abdomen: length 3.2/3.3, width 2.2/2.5. Eye field: length 1.4/1.4, anterior width 2.1/2.0, posterior width 1.9/ 1.8.

Male. General appearance as in Fig. 135 . Carapace moderately high, thoracic part sloping gently, fovea clearly visible. Eyes surrounded by black rings, but rest of eye field yellow, thorax with median area yellowish grey, lateral parts dark brown, margins of carapace lighter. Brown hairs and bristles on carapace, denser and longer on ocular area. Distance between anterior lateral eyes slightly larger than between posterior laterals. Clypeus high, yellow. Chelicerae dark brown, with two promarginal teeth and single tooth on retromargin. Labium and endites brown with paler tips, sternum yellow. Abdomen generally greyish brown with yellowish silver pattern, brown median belt in anterior half of abdomen ( Fig. 135 ). Brown hairs on abdominal dorsum, with long brown bristles among them. Venter light. Spinnerets long, yellowish grey. Legs yellow with brown patches; distal halves of femora darker, tibiae brownish, metatarsi with brown rings at base and tip. First pair of legs long. Leg hairs brown, spines numerous. Three pairs of ventral spines on tibia I ventrally, two pairs on metatarsus. Pedipalps light brown, long. Palpal tibia elongated, with straight apophysis, slightly displaced to dorsal surface ( Fig. 138 ). Bulb rounded, with meandering spermophore, embolus small and thin, placed on tip of bulb, forming very small basal curl ( Fig. 136 ). Additional very thin apophysis accompanying embolus lies behind it, visible only in lateral view ( Fig. 139 ).

Female. Similar to male, slightly lighter coloured, but pattern on abdomen more contrasting. Venter of abdomen with irregular marks and dots. Epigyne with two rounded depressions with delicate sclerotized flanges ( Fig. 140 ). Seminal ducts very short, spermathecae with thick walls, accessory glands located in walls ( Fig. 141 ).
