Type material. HOLOTYPE Australia: New South Wales: 3, Wilganea Station , 5.5 km NW of homestead, 90 km N of Burke, 29°21'16"S 146°16'59"E, 3 Mar 1993, L. Gibson, AMS KS45252 . PARATYPES Australia: New South Wales: 33, ♀, same data as holotype, AMS KS45279 .

Diagnosis. This species is distinguished by its abdominal colour pattern, an embolus that bears a hook-like sclerite, an epigyne without pockets and spermathecae that are relatively small.

Description

Male holotype. Cephalothorax brown. Eye field with numerous reddish hairs and brown bristles, the latter longer anteriorly. Thorax with numerous white hairs. Abdomen beige, lighter posteriorly, with brown chevrons ( Fig. 2C). Spinnerets smudged yellow. Clypeus brown with white hairs, some of them curved down towards chelicerae. Chelicerae brown with lighter chewing margins, promargin with 3 teeth, retromargin with 1 tricuspidate tooth. Maxillae orange, labium smudged brown, both with lighter chewing margins. Venter beige with dark central stripe. All legs yellow except for legs I with darker lateral areas on the femora and smudged orange tibiae. First leg spination as in female (see Fig. 2D). Palpal organ ( Fig. 2A,B). Femur very robust with proximal process. Tibia with two apophyses: ventrolateral massive and laterally bent, retrolateral small, conical. Tegulum with 2 posterior lobes, embolus accompanied by large sclerite with hook-like ending. Dimensions: CL 1.57 , EFL 0.75, AEW 1.14 , PEW 1.07 , CW 1.32 , AL 1.39 .

Female. Thorax brown, eye field darker, eye surrounds black. Whole surface covered with adpressed hairs—white laterally and orange dorsally. Eye field dark with strong dark brown bristles and more delicate, longer bristles around eyes. Abdomen beige with central brownish herring-bone pattern and “panther-like” irregular spots, hair cover of moderate density, light and brownish, with a few brown bristles anteriorly. Spinnerets greyish-yellow. Clypeus darkorange centrally, smudged brown laterally, with numerous white hairs and fewer white and brownish bristles. Chelicerae dark-orange, each with an anterior darker vertical stripe and with yellow chewing margins. Prolateral cheliceral margin with 3 teeth, retrolateral margin with single tricuspidate tooth. Pedipalps orange with yellow and white hairs and brown bristles. Maxillae and labium darkorange with lighter chewing margins. Sternum smudged orange-brown, edged with protruding white hairs. Venter beige, with “panther-like” spots laterally. Legs I moderately robust, yellow-orange, distal femora and joint areas of patella, tibia and metatarsus grey banded. Legs III–IV similar in colour, legs IV with additional prolateral dark femoral stripe. Legs II missing. All legs with numerous orange-brown spines. Hair cover moderate, white, orange and brownish. Epigyne ( Fig. 2E–F). Without posterior pockets, copulatory openings well visible, insemination ducts broad with accessory glands. Spermathecae oval but relatively smaller than in other species. Dimensions: CL 2.07, EFL 0.75, AEW 0.92, PEW 0.89, CW 1.24, AL 2.67.
