Thank you Joshua Gan for identifying this species for us
General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
A medium sized spider that weighed in at 0.37 grams, 15mm long. We are confident it's mature as you can see the pedipalp bulb, etc.
This species has an unusual double tibial spur near it's kneeds on it's front legs.
Unlike most other spiders, but typical amoung Mygalomorphs, these have their eyes very close together.
We found this one male in July.
We thought this was Adelaide's Trapdoor Spider (Blakistonia aurea). Joshua said "Eye arrangement and presence of sigillae on abdomen suggest Idiosoma instead of Blakistonia". The sigillae are the little round pale spots on top of the abdomen.
