NEW SOUTH WALES: 1♂, Newnes SF, Sunnyside Rd, 33°22'33"S 150°11'14"E, 15–30 Nov 2005, GAM et al. AMS KS93056 .

Diagnosis. Male palp ( Figs 20a–b ) with TA consisting of two short, blunt tipped projections. MA with elongate proximal projection curving prolaterally and expanding to paddle shaped tip and with narrow, elongate prolateral projection. Embolus simple, broad at base with small basal expansion and narrow tip. Palpal patella with one dorsal spine, palpal tibia without spines. Female epigynum unknown. Tarsal organ capsulate, situated distally of trichobothria.

Description. Male. Measurements: BL 8.40, CL 4.20, CW 3.20, PLE 0.30, PME 0.20. Female. Measurements: BL 9.95, CL 4.20, CW 2.85, PLE 0.32, PME 0.24. For morphological description see species diagnosis and generic description.

Etymology. The specific name is a noun in apposition taken from the type locality.

Distribution. Known only from the vicinity of the type locality in the ACT and Newnes SF in NSW ( Fig. 27c ).

Remarks. The two female specimens attributed to this species have their epigyna plugged making the morphology unclear. For this reason the epigynum has not been illustrated. However, following the law of parsimony they have been attributed to S. picadilly , the only known sympatric species of similar size.
