Diagnosis. Male palp ( Figs 25a–b ) without obvious TA but with slight expansion at base of embolus. MA compact with elongate prolateral projection but no other pronounced projections. Embolus broad with median expansion, abruptly narrowing to pointed tip. Cymbium without basal swelling but with two to three stout basal prolateral macrosetae. Palpal patella with single stout dorsal hair, palpal tibia without spines. Female epigynum ( Figs 25c–d ) with small lateral teeth. Tarsal organ capsulate ( Fig. 8d,h ), situated distally of trichobothria.

Description. Male. Measurements: BL 6.80, CL 3.50, CW 2.75, PLE 3.40, PME 2.50 (AMS KS44941). Female. Measurements: BL 8.05, CL 3.30, CW 2.85, PLE 3.40, PME 2.50 (AMS KS45290). For morphological description see species diagnosis and generic description.

Etymology. The specific name refers to the known range of this species, the state of Victoria. It is a noun in apposition.

Distribution. Known only from Victoria ( Fig. 27b )

Remarks. The presence of stout prolateral basal macrosetae on the male cymbium suggests that this is the sister species to S. terraneum , the only other species in the genus with this feature.
