Primarily found in Asia, there is also a population of A. karschi in southeastern Pennsylvania.

[4] They have large chelicerae in comparison to their body size, which point downwards as characteristic of mygalomorphs.

Males leave their tubes once they reach maturity and wander in search for a mate, while females usually spend their whole lives within their burrows.

[2] The spiders use projectile excretion to safely defacate from within their tube, and some researchers suspect that the spider uses their excretion to create a V shape on the ground and funnel prey towards the tube.

[5] Young spiderlings traverse via ballooning, something that is rare among mygalomorph spiders.
