Figs 2–9

Type material. Holotype: 1♀, 200m E of Mungindi Rd., 3rd cattle grid after entrance to ' Abeddar' Station , equivalent to NPWS site NWB0283, New South Wales, 148.9°E, 29.18°S, L. Wilkie, R, Harris, T. Moulds, 27 Nov. 1999, (AMS, KS74248) . Paratypes: New South Wales: 1♀ as for holotype, (AM, KS74249) ; 1♀ 21.1km N along Castlereagh Highway from turnoff to Lightning Ridge, W side of road, 148.12°E, 29.17°S, F. Christie, P. Flemons, M. Elliott, 22 Nov. 1999, (AMS, KS74246).

Etymology. The name of the type locality, treated as a noun in apposition.

Diagnosis. Widest point of the cephalothorax well behind PLE. There is a thin, grey, clypeal fringe and each palp is brown with white femur. Copulatory openings distant from the spermathecae and further apart than the width across the entrances to the fertilization ducts. Unlike all other species, the fold back in each insemination duct extends beyond the anterior edge of the spermatheca and then folds forward again before joining the spermatheca close to the entrance to the fertilization duct.

Description. Female: Cephalothorax mid to dark orange. Surrounds of ALE, PME and PLE, darker. Pars thoracica without markings. Clypeus narrow, mid-brown, with a thin fringe of grey hairs. Chelicerae bulbous, mid-brown. Two promarginal teeth and one small, blunt, retromarginal tooth. Endites and labium off-white, brown at base. Sternum dirty brown. Dorsal abdomen heart-shaped, light brown with darker lace-like patterning forming vague stripes posteriorly. Spinnerets mid brown grading to light brown. Ventral abdomen light, grey-brown. Palps bulbous, pointed distally, light brown, tibia and metatarsi mid-brown. Palp with a sparse covering of long grey hairs. Legs very light brown with mid-brown tibia and metatarsus. Large strong spines, L1 similar build to other legs, without a fringe on patella and tibia. Epigynum: The epigyne includes a pair of oval-shaped atria with clearly delineated guides. The copulatory openings are anterior to the guides, a short distance anterior to the spermathecae. There is a gland on the side of the insemination duct close to the copulatory opening. Each insemination duct includes a long loop extending from the posteromedial edge of the spermatheca to beyond the distal edge of the spermatheca before connecting to the anteroventral face of the spermathecae. The spermathecae are within the atria and close to the epigastric fold. Fertilization ducts open onto anterior extensions of the spermathecae. Dimensions (Holotype): CL 1.4, EFL 0.55, AL 1.65, CW 1.1, AEW 0.9, AMEW 0.55, PEW 0.9, L1 2.15 (0.75+0.35+0.4+0.35+0.3), L2 2.15 (0.7+0.2+0.75+0.3+0.2), L3 2.65 (1+0.5+0.45+0.4+0.3), L4 2.7 (1+0.45+0.5+0.3+0.45).

Male: Unknown

Distribution and Biology. The species has been collected at two sites using pitfall traps and is ground living in woodland west of the Great Dividing Range in north-eastern New South Wales ( Fig. 9 ). Due to the limited distribution data, recommended IUCN Red List Category DD. Because of its limited known range it may be at risk through climate change or habitat loss or degradation.
