Varying sizes. At least 10 small spiders in their own nest, with one adult female (photos 4 & 5). At least one young spider still resident in the adult's nest (photo 3).
Definitely not Stanwellia sp., nor any other of infraorder Mygalomorph. At a glance looks more like family Lycosidae (Wolf spiders), or similar, of Araneomorph infraorder, or modern spiders.
Images 1, 4 and 5 are Portacosa cinerea. Images 2 & 3 would be better as a separate sighting - they are either young P. cinerea, or a different species (of wolf spider) altogether.
Hi Kim, I've removed image 2 and replaced it with the adult spider that was in the same hole as the juvenile in image 3. I didn't include it before as you can't see its back so not sure if you can identify it. This may however help with the ID of the spider in image 3.
Thanks Alison. The spider in image 3 looks a bit different, but I will now assume it's the same species if they were in the same burrow. I can't imagine a wolf spider being very tolerant of another unrelated spider in its own burrow!
