Thank you Chris Cohen for identifying this species for us
General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Abundant in Feb & March; having photographed 9 females.
1. Thick, glabrous arista
2. White halteres
3. Orange around the leg joints
4. Shiny black upper abdomen
5. Grey under abdomen & body. Possibly thick short grey hair, hiding the 'skin' colour
6. A strange propensity to stand head down bum up.
7. ~9->11mm long; some slightly smaller than others.
8. Significant swelling "seams" down the side; longitudinal wrinkles that seem to allow the abdomen to swell up. When gravid or large meal?
9. Long rear & middle legs, with thick thighs, supporting their propensity to stand head down.
10. Brushed hind legs.
We thought this might be Harpagobroma genus, but Chris lifted our id up to sub-family level, saying: "Because an apical spine appears to be present on the fore tibia, this is either Austrosaropogon or the undescribed genus Saropogina."
"Although I'll note that Saropogina and Harpagobroma are likely closely related, differing mostly by the presence/absence of the fore tibial spur."
