I wish I had a sound file to post.
The Razor Grinder is found in eastern Queensland and NSW, and most common in December & January (Moulds, M.S.. Australian Cicadas Kennsignton: New South Wales Press, 1990, p. 68.)
This looks exactly like a host that we have at the moment at Caniaba NSW. Do they have an orange pair of little shields underside? We hsve had them for several weeks and thrust are deafening! Quiet ending a little now and a few dead ones bring found.
