Thank you Mark Hura for identifying this species for us
General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
1st Live Photo's on-line: ~17 to ~21mm long. Marie found all 3; the first (male) was dead on the ground; the other female & male were found live on the ground.
We spent hours trying to id it via photographs and thought it was Novapus crassus, a very similar species.
Mark said "It exhibits all the features of this species - pygidium setose on base and apical ridge; mentum setose on disc; deep, abrupt pronotal excavation with shallow vermiform punctures on the disc; large bifurcate cephalic horn; subobsolete upper carina on hind tibia as well as a number of other features."
In 1887 Rev. T. Blackburn states of this species (which he described) "I have seen a good many specimens taken in the Adelaide district.". It's a pity they are so rare today.
The females don't have the horn, nor the depression.
The female was found in May, while the 2 males were found in June.
