Of all these following 7 natives, which do you think is the closest visually to what you've found?

It does have a partial resemblance to the fifth spider down but the legs on my spider are thinner and the claws on the end of the feet are much smaller and less bulky. The claws are more like those on the sixth spider. Though the sixth spider doesn't have much setae whereas mine has lots. Additionally, there looks like there's a bit of an attractive pattern on the fur on the carapace that I don't see on any of these spiders.

this is getting so interesting, now i just have to see them XD
I should be able to post a photo tomorrow after I do some Raw processing.

regrettable that it escaped, they are much stronger than they appear
This is actually the second escape Ive had. I did catch another one about a year ago which looked like the same species. And it was also found outside my bedroom door. I only had that one for one night. In the morning, I discovered that it had escaped. So for the more recent mygalomorph, I tried to make the container escape proof by placing camera equipment over the top. It looks like that wasn't sufficient.

Yea I know that tarantulas are a lot stronger than most people think. Though this mygal is smaller and skinnier so I didn't think it would have the same strength. I guess I was wrong. It looks like my thread title has even more relevance now lol.

It doesn't and they don't, but toss in a 3rd class lever operating a 1st class lever and maybe add an inclined plane and we will be talking some serious force. Animals are constantly amazing.

Those things wouldn’t ever escape any of my tanks . Haha 😆..
hope you find the species but it could be a undescribed one. I’ve seen spiders before that I never found pics of in any local native species and I don’t even live in the tropics . Saw some pretty big crab spiders too once in the county 3”+ . Unfortunately in the city I don’t see much of anything.

Perhaps Teyloides bakeri? Males are a little more hirsute but they are the only thing I can think of with a notable marking on the carapace. According to ATLA they are definitely on the island as well

Other question to help narrow it down, do you recall whether or not it had prominent spinnerets? The answer would immediately narrow it down amount. Longer spinnerets would point towards an Anamid such as Teyloides, short/barely visible ones would point towards Idiopidae or Barychelidae such as Idiosoma or Idiommata

I was taking the length of the spinnerets into consideration when I was looking at your supplied pictures last night. My spider had very short / barely visible spinnerets. That's why I selected the fifth and sixth spiders due to their short, stumpy spinnerets (and other features.)

Actually, it does look quite a bit like an Idiommata species silverback brush footed trapdoor spider but without the silver back. I notice some brush footed trapdoor spiders vary quite a bit with thier build. Some appear to be rather bulky and others are more slender. Mine one was slender. Though I don't suppose the difference in build is due to gender? Mine was male as there are spurs on the front legs. Would females be more bulky? I had a male with a brown back.

Oh I'm sure your enclosures are escape proof. The plastic containers that I placed these mygalomorphs in were only meant to be temporary. I was planning to transfer each one to a glass aquarium.

Woah they sound like huge crab spiders. I thought they were generally tiny. Crab spiders must not be common where I am. I have only ever seen once and that was in the backyard. It was on a daisy and I saw it catch a tiny winged insect.

Only male Idiommata possess the silver colouration, and the silver is so pronounced even the dullest of males is 100% recognisable

Yea I gathered that from my brief online research.

I did some more digging around online and I came across a brush footed trapdoor spider known as Seqocrypta jakara. And my male is just about a spitting image of the male jakara. Very likely, it's within the same genus at least. Though Seqocrypta are found in Queensland. Apparently, the 'Seq' in the Seqocrypta name stands for South East Queensland. Ive seen a few of these guys here over the last two or three years. All presumably males looking for a female. If they really are from within this genus, I wonder what they're doing here on Kangaroo Island in South Australia. I can only assume they were introduced here (either accidentally or intentionally.) Perhaps they were introduced here a few years ago which probably explains why I didn't see them here in the past - only relatively recently. Another thing Ive noticed is that they are generally very lethargic - like they're lacking energy. That might be due to the cold climate of the island. They would be more used to Queensland where it's often warmer.

Here's an interesting video about Seqocrypta jakara.


One thing though - I can't see the spurs on the front legs of the mature male at 1:00 in the video. The spurs on my male are quite prominent.

Far more likely to be Synothele down your way, even though it's still a long way from their home, it'd be the more likely option.

Synothele from WA

Being a Barychelid would also explain the escape artist behaviour, as they are only myg family besides T's capable of climbing smooth surfaces

Good to consider Synothele also as a possibility. Ive checked out some more photos from that genus but hard to tell if any of the ones featured are male. I couldn't see any spurs on the front legs. I do see many similarities with Seqocrypta. The pattern on the carapace looks identical. And just like Seqocrypta, there are more spines on legs III and IV compared to the other legs. Though from the photo I took, I don't think it looks like there's a raised triangular section which is a feature of Seqocrypta jakara.

My family has been visiting this part of the island for well over 20 years. And I have never seen these mygalomorphs here before. Odd that Ive only started seeing them here in about the last 2 - 3 years.

And I'm sorry for the delay with the photo. Ive been busy with other stuff. I should be able to process the Raw file soon and post it.

Bary's are some of the most elusive mygs in any area, their burrows are often expertly camoflauged and some of the trickiest to spot. Not to mention some like Sason colemani are arboreal and almost invisible unless the tiny lid is lifted.

Getting those raw files processed would be awesome, very little myg news comes out of kangaroo island and most Aussies have hardly even heard of Moggridgea

Oh yea coming across a trapdoor in the wild would be like mission impossible. My father did manage to find one on the family farm (elsewhere on the island) some years ago. Though the spider in that trapdoor didn't look like a mygalmomorph.

During the last 2 - 3 years, Ive come across four mygalomorphs around my home. The first two were found indoors (in and around the bathroom.) The last two were right outside my bedroom door (on the slate.) They were all individual sightings (seeing one at a time) usually several months apart. Though if I recall, the first two indoor sightings were pretty close together - maybe by about one or two weeks.

On Atlas Of Living, theres loads of myg sightings from a number of families across the whole island, including some lid building Idiopids like Idiosoma subtriste. There's definitely plenty to be found in the right spots.

Heck, there's even mouse spiders in the form of Missulena insignis

I admit I know so little of the native mygalomorphs (except for our tarantulas.) It sounds like it's quite a vast field with many genera and species of trapdoor and funnel web spiders, mouse spiders etc. So much to explore.
