Have only ever seen one of these.
Rentz & Su state they are a Northern Australia species, so I'm concerned over my id. But there's nothing else in the book that looks like it.
There may have been sightings near Perth, so perhaps they are more southerly than previously thought?
Incredibly long ovi-positor, ~1.5 x body&head length. Wingless.
