This lacks the prominent blackish longitudinal stripe in the anterior half of the abdomen, which is diagnostic for Holconia spp. The flattened carapace and the presence of pairs of blackish spots on the abdomen place it in Isopeda. It looks like Isopeda montana, a species we have recorded far south in Wonboyn. But I’d need a view of the underside of the spider and high power images of the pattern of hairs on the first trochanter to be sure of that. So I’d suggest leaving it at Isopeda sp.
