In lieu of a comprehensive study or guide to the larvae of the nearly 60 species in subfamily Perginae; subfamily level identification is the only valid option.
Cephalic (head) region is covered in setae (hair like structures), which all Atracids (Australian funnel webs) lack. The pedipalps (the smaller leg like structures that are between legs 1 and the fangs) are bigger than what would be expected in Atracids. The chalicerae (what connects the facts to the cephalothorax) are much smaller than what would be expected in Atracids. The layout of the eyes would be different between the two groups as well, slightly different, but noticeable with a close up photo.
Arbanitis belongs to the family Idiopidae which are commonly referred to as trapdoor spiders. I hope this is helpful and may be handy in any future encounters with mygalomorphs
Peppermint type bark, and fruits are truncate-globose, so it looks like narrow-leaved peppermint . Juvenile leaves would confirm. For now best to list as Eucalyptus sp.
Oohh!!! On a previous visit (with Jennie W) we confirmed the call as WK. I'll aim to get back there and see if I can get better shots. Or maybe you could come with me sometime? They seem to be hanging around in the area.
