General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
We found 4 specimens, 3 x female & 1 x male in July & August.
Very dark crickets with few markings; males are black while females are dark brown. They have not discernable face markings, which is unusual for crickets.
The females have small pale pairs of spots on their backs (not always visible). Her ovi-positor sheaths have serrated tips.
Females are ~6mm, with ovipositor ~3-4mm, while our male was ~4mm.
Both genders are wingless.
These are well known in the Murray Mallee, and are often found with Ottes Pygmy Cricket (Calperum ottei) in smaller quantities; which we've also experienced.
