Hi Wandiyali - this seems to be another uncommon species for your property. There are no electronic records of this species. I don't know how many specimens there may be in the National Insect Collection but from what I can tell it has been rarely reported.
This species has been incorrectly identified (mostly by me) as T. Albosignata and is not uncommon in the ACT but easily overlooked. I have asked for more info from Youning.
