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

Diagnosis. Lateral receptacles of the spermathecae do not extend as far forwards as the atria. Lateral and medial spermathecal receptacles are almost the same size with a longitudinal cleft between them. Atria, including copulatory openings, are close together, directly anterior to the medial spermathecal receptacle and are much larger than receptacle. Fertilization ducts extend from distinct dorsalwards extensions in the middle of the dorsal surface of the median receptacles. Abdomen has no large lateral bulges. Clypeus has short fringe of white hairs. Palps are light brown covered with long white hairs. Each metatarsus is rounded with a white tip and a pair of large darker spines. Patella, metatarsus and tarsus of L1 are off-white. Males are paler colored than females, Clypeus has a short thin white fringe. Palp is off-white with a white tip. L1 is off-white. There is a darker, sparse femoral fringe on L1. The tegulum is mid brown and the tibial apophysis is of medium length, pointed, directed away from the palp. The base of embolus is hidden behind a tegular shelf. The embolus proceeds laterally across the distal edge of the tegulum before moving distally in a simple curve at the mid-line without curving away from the face of the cymbium.

Description. Female: Cephalothorax mid brown with thin covering of white hairs around the sides. Surrounds of ALE, PME and PLE, black with a thin covering of long white hairs. Pars thoracica without markings but edges black. Clypeus narrow, mid-brown, with a thick fringe of white hairs. Chelicerae mid-brown. Two promarginal teeth and one small, sharp, retromarginal tooth. Endites and labium off-white, brown at base. Sternum white. Dorsal abdomen light brown with a pattern of dark stripes. Spinnerets light brown with dark patterning. Ventral abdomen light brown. Palps narrow, brown, pointed distally, metatarsal tip light brown. Palp with a covering of long white hairs. Legs mid-brown with darker transverse stripes. Large strong spines, L1 more strongly build than other legs, with a thin fringe of long stiff hairs on the ventral femur. Epigynum: The atria are well sclerotised and are placed a short distance anterior to, and in line with, the medial spermathecal receptacles. Each insemination duct extends from the anterolateral edge of the guides and then passes down the dorsal side of the medial spermathecal receptacle close to the mid line. They open into the spermatheca from the dorsal surface, close to the broad connection between the lateral and median receptacles. The spermathecae are placed close to the epigastric fold and the receptacles are of almost equal sizes. Fertilization ducts extend from extensions in the middle of the dorsal surface of the median receptacles. Dimensions (Holotype): CL 1.45, EFL 0.6, AL 1.75, CW 1.25, AEW 1.3, AMEW 0.8, PEW 1.25, L1 3.15 (1.2+0.45+0.75+0.4+0.35), L2 2.65 (0.75+0.45+0.7+0.4+0.35), L3 2.75 (0.9+0.45+0.5+0.5+0.4), L4 3.3 (1+0.4+0.7+0.75+0. 5).

Male: As for female. Sparse white clypeal fringe. L1 with sparse longitudinal fringes on the dorsal surface of the femur and the ventral surface of the tibia. Palp: Tibia with single short, stout tibial apophysis that projects outwards. Each embolus appears in the distal corner of the tegulum with its base is obscured by a tegular shelf. The embolus moves in a lateral direction before curving distally. Dimensions (Paratype): CL 2.1, EFL 0.95, AL 1.8, CW 1.75, AEW 1.75, AMEW 1.1, PEW 1.6, L1 3.85(1.6+0.55+0.65+0.55+0.5), L2 3.3 (1.1+0.6+0.65+0. 5+0.45), L3 3.9 (1.4+0.6+0.65+0.7+0.55), L4 4.35 (1.5+0.6+0.8+0.95+0. 5).

Distribution and Biology. Found in litter in rainforest in southern and central eastern Queensland ( Fig. 19 View FIGURES 15–19 ), as a consequence, likely IUCN Red List Category LC.
