Diagnosis. This is a small species (CL, <3mm), in which the fertilization ducts are short and the insemination ducts reach the anterior edge of the fossa. It is distinct from all other species in the genus as the origin of the embolus is near the proximal rather than distal edge of the bulb. A median black mark is found on the posterior edge of the abdomen unlike all other species. When visible there is a distinctively shaped pattern in the middle of the dorsal abdomen.

Description. Male: Cephalothorax dark orange covered with pennate ginger-brown hairs over dorsal surface with pennate grey hairs on the posterior and lateral surfaces. Integument surrounding ALE, PME and PLE black with thick covering of grey hairs. Clypeus narrow with long sparse fringe of grey hairs. Chelicerae long and strongly geniculate, dark tan with sparse covering of long white hairs on the proximal and median areas. A toothlike protuberance, projecting forwards off a large mound on the anterior face of each chelicera, a cluster of three large promarginal teeth and a separate small tooth on a single base and one large straight fissident retromarginal tooth. Endites and labium tan grading to yellow, sternum tan. Abdomen without a central anterior cleft, yellow with dark brown mid line stripe and brown patterning that reach the margins. Pattern highly variable, constant features are the black mid line marking at the posterior end of the abdomen and the shape of the chevron (when present). Ventral abdomen same colour as dorsal surface of the abdomen on the sides with a black central section. Spinnerets yellow. L1 longer and a little more robust than L2, L3 and L4. Femora of L1 and L2 brown with dark brown anterior lateral and ventral patches covering over half the segment. L3 and L4 femora with three transverse dark stripes.L3 and L4 femora, and all patellae, tibias, tarsi and metatarsi yellow, without fringing. Patella plain, tibia with two transverse brown bands, metatarsus with a single transverse band and tarsus with two transverse bands. Palp ( Figs 51–53 ): brown, tibia with single slender apophysis. Tegulum relatively broad with anterior lateral lobe and a proximal lobe, origin of the embolus proximal, forming a tapering single anticlockwise spiral around the bulb. Dimensions: CL 2.7±0.10 (16) (1.98–3.22), EFL 1.16±0.04 (16) (0.93–1.36), CW 2.11±0.08 (16) (1.49– 2.54), AEW 1.90±0.06 (16) (1.42–2.17), AMEW 1.12±0.03 (16) (0.87–1.30), PEW 1.79±0.06.

Female: Cephalothorax dark orange covered with pennate grey hairs, thicker on the posterior and lateral surfaces. Integument surrounding ALE, PME and PLE black with covering of grey hairs. Clypeus narrow with long sparse fringe of grey hairs. Chelicerae geniculate, dark tan with a sparse long white hairs on the front face, four promarginal teeth on a single base and a single, large, fissident, retromarginal tooth but no protuberance on the front face. Endites and labium mid brown grading to yellow. Sternum mid brown. Abdomen with a slight central anterior cleft, yellow with dark brown to black markings. Pattern highly variable, constant features are the black mid line marking at the posterior end of the abdomen and the shape of the chevron. Ventral abdomen same colours as dorsal surface of the abdomen on the sides with a black central section. Spinnerets yellow. Palps orange with darker transverse bands. L4>L3> L1>L2, all relatively slender. Legs yellow grading distally to mid brown, femur without three dark brown transverse bands, patella with a single transverse brown band, tibia with two transverse brown bands and metatarsus with two transverse bands and tarsus with a single transverse band. Epigynum: consisting of two large fossae and a darker sclerotised margin. A distinct brown patch varying in shape and position is sometimes found in the middle of each fossa. Guides and copulatory openings indistinct. Guide consistent in shape but varying in position with different parts emphasised in different specimens. Anterior edge of the insemination duct beyond or near the anterior edge of the epigynum. Posterior edge of the insemination duct in line with or anterior to the matching edge of the guide. Accessory gland in the distal third of the insemination duct. Insemination duct passes laterally across the anterior part of the fossa to the mid line and then move posteriorly until entering the spermatheca on the posterior mid line. Spermatheca pear-shaped and within the margin of the fossa towards the posterior edge. Right and left spermatheca touching, insemination ducts well separated. The fertilization duct is short, arising from a branch of varying length off the anterior edge of the spermatheca and curving dorsally in a tight circle. Dimensions: CL 2.77±0.04 (26) 2.35–3.10, EFL 1.22±0.02 (26) 1.02–1.36, CW 2.27±0.03 (26) 1.98– 2.54, AEW 1.98±0.02 (26) 1.86–2.11, AMEW 1.1±0.01 (26) 1.05–1.30, PEW 1.91±0.02 (26) 1.67–2.11.

Distribution and biology. Only found to the east of the Great Dividing Range from southern NSW to central Queensland ( Fig. 54 ), though predicted to be found in Victoria and South Australia. Found under bark in eucalypt forest and woodlands. Likely IUCN Red List Category LC.
