Thank you Caitlin Henderson (ShesGotLegs) for identifying and Suzanne and Jim for confirming the id of this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~13mm long. We thought it was Eriophora biapicata.
Caitlin said "The reduced humps are a puzzle."
Suzanne & Jim said "It's easy to see the way the scape kinks up and back down right at the end, something you see in Backobourkia."
