General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
The male specimen shown here (found on Ellura) was in poor shape, malnourished and had lost appendages; missing front leg and one palp. Also it's not possible to see the fangs, so may have also lost them causing the malnutrition. Notice the tibial spur on the 2nd leg of the male. This spur is more forward, compared with the Spurred Orb Weaver (Novakiella trituberculosa); only on the male as they are used when mating to stop the female from invenemating him. This spur is more noticable on this specimen as the front leg isn't blocking the view.
The female was found in the Adelaide Hills, some 80kms away. Amazing glod patterns on her back.
Eriophora are highly variable and impossible to separate to species photographically. We have chosen E. biapicata based on location. E. transmarina being more along the Eastern seaboard and not in arid environs.
Both male & female have very spiny legs, which isn't normally very obvious, but with black hairs and golden spines they stand out quite clearly with these specimens.
These are now Hortophora biapicata, but it takes a while for Atlas to catch up with new binomial names.
