General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
1st Live Photo's on-line: We found 3 specimens, 2 x female & 1 x male in January, July & August. Given they are a winter species, the January sighting is strange. It was a hot, wet summer.
Mottled reddish brown crickets with a couple of dark abdominal bands and 2 diagnostic central pale dorsal spots. They have a distinctive horizontal black band covering the lower half of their face; which carries through their eyes.
Her ovi-positor sheaths have finely serrated tips; possibly the reason for the families other common name of "Sword-tail" Crickets.
Females are ~5-6mm, with ovipositor ~3-4mm. We didn't measure our male but according to our source "A guide to Crickets of Australia" by Rentz & Su, males are slightly smaller.
Both genders are wingless.
These are well known in the Murray Mallee, and are often found with Mallee Dwarf Cricket (Territirritia tya) in larger quantities; which we've also experienced.
