Thank you Tony Daley for confirming the identification of this species

General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
S9 was caught at Ellura and measured at ~7mm.
These differ clearly from T. digitata & T. paramonovi by the thick white/silvery edge/line running longitudinally above the eyes (edge of the frons) to the neck. The other two species have very thin lines as well as different shaped legs.
The description notes the antennae are black, but you can see here the antennae are covered in the fine pale/silvery hair and explains why the antennae don't appear black in all on-line photo's.
For clarity, Tony kindly confirmed S8 & S9.
