Unidentified

Hi Ross - I searched for Family Nicodamidae images and found this site:
https://ednieuw.home.xs4all.nl/australian/Nicodamidae/Nicodamidae.html
And a good likeness of your spider with this note ;
"Nicodamus peregrinus was formerly called Nicodamus bicolor. The common name of this spider is Red and black spider."
So far so good. I then went to this site:
http://www.findaspider.org.au/find/spiders/516.htm
Which had the spider as Nicodamid species formerly Nicodamus bicolor. It also had this disquieting explanatory note:
"Note that in the revision of the nicodamid family published by Dr Mark Harvey of the Western Australian Museum in 1995 the original single species was expanded to 7 genera containing 23 species, almost none of which can be identified with certainty without a close examination of the male and female genital structures."
So I think that leaves us waiting to see if Kim thinks we can call it Nicodamus peregrinus or Nicodamid species.

Looks like it might go Nicodamid species. I was lucky enough to get a poor quality photo of the tiny spider but wouldn't have been able to take the ID further because I don't try to catch what I find. Seems we'd need to catch and examine under a binocular microscope so I'd be happy with Nicodamid species if that's the call.

Hi Ross, Max - I'm probably going to add to the confusion here ...
I think it might be Ambicodamus southwelli. Last week, just a few days before your sighting Ross, I photographed one in our region. As you say Max, the whole group is rather tricky, as many species have been apparently mis-identified as Nicodamus in the past. Anyway, I'll post my photos and explain the logic to my ID. But, in short, yours looks very very like my guy, and the timing and location is a pretty good argument for them being the same species.
