General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~13mm long. No visible pattern on the thorax.
Males and females for this group are easily separated by the distance between the eyes. You can clearly see the male's eyes touch, the female's eyes are separated.
Interesting to note, you can't see the male ocelli; but they are visible on the female - albeit, very small, probably defunct.
