Type material. Holotype: 1♀ Banyabba State Forest , New South Wales, 152.12°E, 29.4°S, A. York, Feb. 1997, (AMS KS97146) ; Paratypes: New South Wales: 1♀ 5.9km NE from creek crossing on Morgon Creek . leasehold land, 152.32°E, 28.78°S, G.A. Cassis, M.R. Gray, (AMS KS 38398) ; 1♀ Fortis Creek State Forest , 152.85°E, 29.43°S, A. York, Feb. 1997, (AMS KS97153) .

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

Diagnosis. Sides of the cephalothorax parallel, palps brown with a light brown femur and long grey hair covering. Copulatory openings close to the spermathecae and closer together than the width across the entrances to the fertilization ducts. Unlike all other species, the fold back in each insemination duct includes only a single, short loop (one quarter length of spermathecae). They are placed alongside the medial edges of the spermathecae and join the posterior edge of the spermatheca.

Description. Female: Cephalothorax mid to dark orange. Surrounds of ALE, PME and PLE, orange. 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 light, grey-brown with darker lacey patterning. Spinnerets grey. Ventral abdomen light, grey-brown. Palps grey-brown, tibia and metatarsi dark brown. Palp with a sparse covering of long grey hairs. Legs very light-brown with dark 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 faintly-delineated guides. The copulatory openings are anterior to the guides, a short distance anterior to the spermathecae. Each insemination duct includes a short loop (quarter the length of the spermatheca) on the posterolateral edge of the spermatheca, before connecting to the posterior edge of the spermatheca.The spermathecae are within the atria which are close to the epigastric fold. Fertilization ducts open on to anterior extensions of the spermathecae. Dimensions (Holotype): CL 1.7, EFL 0.65, AL 1.7, CW 1.3, AEW 1.05, AMEW 0.85, PEW 0.95, L1 245 (0.75+0.5+0.45+0.4+0.35), L2 2.4 (0.75+0.5+0.5+0.35+0.3), L3 2.95 (1+0.5+0.5+0.5+0.45), L4 3.25 (0.9+0.45+0.9+0.6+0.4).

Male: Unknown

Distribution and Biology. The species has been collected using pitfall traps at three locations and is ground living in forest east of the Great Dividing Range in north-eastern New South Wales ( Fig. 17 ).). 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.
