General Species Information:
Found in the Adelaide Hills and possibly elsewhere
Male & female ~13mm long. To separate species within the genus the male is needed. These can be recognised by the long thick antennae bases as seen here.
In SA we have two very similar species, E. grandis & E. rufescens. To separate them you need to see the antennae segments. The middle & rear leg spines also help. E. rufescens has longer middle leg spines but a slightly smaller rear leg spine than E. grandis.
With E. grandis the middle antennal segments also have slight spuring (similar to the 2nd to last two, but not as exaggerated). With E. rufescens the middle antennal segments are relatively symetrical ... round, not spurred.
We cannot confirm the females shown here are E. rufescens, but given the one male we found is, and they were found in close proximity it's reasonable to assume they are.
We found 7 specimens, one male, in Nov, Dec, Jan & Feb.
