General Species Information:
Found in the Riverland and possibly elsewhere
She was a large lady, ~13mm, almost as big as an Australian Orb.
With many spiders the ventral patterns are more diagnostic than the dorsal pattern. Like red backs can have very variable colours on top, but always a red hour-glass under.
Here the ventral patterns are very typical of this species, but the dorsal shot is more washed out than any we can find. They usually have dark bands across the abdomen, but here, she's very silvery all over.
She built her web in Porcupine Grass (Triodia scariosa) and dropped down amoungst the needles when we approached.
