The name reflects the Western Australian origin of the type material and is to be treated as a noun in apposition. Diagnosis. Widest point of the cephalothorax behind PLE. The female has a white clypeal fringe. Palps dark brown with white femurs and long white hair covering, white with off-white tibia and metatarsals and long grey hair covering. Copulatory openings far from the spermathecae and as wide apart as the width across the entrances to the fertilization ducts. Unlike all other species, each insemination duct includes tight coils on the posteromedial edges of the spermathecae. The ducts pass down the medial edges of the spermathecae and join the posterior edge of the spermatheca. The male has a strong white clupeal fringe and white fringing on the sides of the palps. Unlike the other species, each embolus in placed on the posterolateral side of the palp, where it forms two circuits before passing distally beyond the tegulum. Description. Female: Cephalothorax mid to dark orange with pars cephalica somewhat darker. Surrounds of ALE, PME and PLE, orange. Pars thoracica with white patches along the sides. Clypeus narrow, mid-brown, with a thick fringe of white hairs. Chelicerae straight, mid-brown.Two promarginal teeth and one small, sharp retromarginal tooth. Endites and labium off-white, brown at base. Sternum dirty brown. Dorsal abdomen grey-brown with dark grey markings. Spinnerets yellow. Ventral abdomen grey-brown. Palps white and covered with long white hairs. Legs very light-brown with dark grey markings. Medium sized 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 placed in line with the guides and are placed anterior to, but distant from, the spermathecae. There is a gland on the side of the insemination duct close to the copulatory opening. Insemination ducts form tightly coiled spirals on the posterolateral edges of the spermathecae, before connecting to the spermathecae. The spermathecae are within the atria which are close to the epigastric fold. Fertilization ducts leave from anterior extensions of the spermathecae. Dimensions: CL 1.8, EFL 0.75, AL 2.0, CW 1.3, AEW 1.15, AMEW 0.75, PEW 1.05, L1 2.35 (0.6+0.5+0.5+0.35+0.42), L2 1.8 (0.5+0.3+0.45+0.3+0.25), L3 3.05 (1+0.6+0.5+0.5+0.45), L4 3.5 (1+0.6+0.9+0.55+0.45). Male: As for female, except with a thick, white clypeal fringe and white facial setae. Palp: light brown, tibia with single, medium-length apophysis with a hooked end. The tegulum with, rounded, proximal lobe and a small distal projection beside the embolus. Each long embolus is placed beside the tegulum and forms and completes a full circle before moving distally. Dimensions (Paratype): CL 1.7, EFL 0.85, AL 1.3, CW 1.25, AEW 1.05, AMEW 0.7, PEW 1., L1 2.45 (0.85+0.4+0.5+0.4+0.3), L2 2.4 (0.85+0.4+0.45+0.4+0.3), L3 2.8 (0.7+0.6+0.5+0.55+0.45), L4 3 (1.1+0.35+06+0.55+0.4). Remarks. The structure of the male embolus in this species is distinctively different to that seen in the other species, raising the question as to whether it is actually the male of Barraina occidentalis. The specimen was collected along with two females at the same time and location. The dorsal color and setae patterns are very similar except, for the anterior differences seen between males and females in this genus. The strong white clupeal fringe and white facial setae are similar to that in other Barraina species. Distribution and Biology. In litter, in dry sclerophyll woodland and in Trioda (Fig. 40). The species is widespread along the western edge of West Australia and found in reserves.As a consequence, recommended IUCN Red List Category LC.
