I agree Harrisi - I've photographed this at ANBG and have my photo tagged "Arbanitis robertcollinsi". In tree fern.

Interesting Bron, will have to look that species up. I've had trouble uploading this sighting and still wasn't working, or visible my end, and then I saw your relevant comment pop up! Thanks :)

I'm having trouble with all postings etc today as well - perhaps more updates are in progress? Where did you see this spider - it's not showing on the page.

Hi Bron, was wondering how you came to the conclusion of A. robertcollinsi ? Just looked at the definitive paper re this genus and had trouble differentiating between the three species via pics available. The main thing in your suggested species favor is that it inhabit the cooler habitat of the three species which may help it to succeed here in Canberra. Here is the link, have a crack: Raven, R.J. & Wishart, G. (2005). The trapdoor spider Arbanitis L. Koch (Idiopidae: Mygalomophae) in Australia. Memoirs of the Queensland Museum 51(2): 531-557.

Thanks Harrisi I enjoyed the article. The spiders seem to have been introduced to the ACT with the tree ferns they live in ("DISTRIBUTION & HABITAT. Arbanitisis known only from southeastern Queensland, including the Lamington Plateau and just southwest of that area in northern New South Wales. Most localities are rainforest, wetsclerophyll or heath with some populations in open forest.) I'd be curious to discover from where the tree ferns were sourced, as it'd probably help to determine the species but perhaps pointing out their existence to the ANBG might force them to rid the gardens of an introduced species which would be really sad. I'll withdraw the suggestion.
