Atrax

Atrax is a genus of venomous Australian funnel web spiders that was first described by O. Pickard-Cambridge in 1877 from the type species Atrax robustus. It contains five species. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, then to the Australian funnel-web spiders in 2018.

== Description == They are medium to large spiders for their family, ranging from 1.5 to 4.5 cm. As most in the Mygalomorphae infraorder, they have robust bodies, with a glossy dark colouration in their carapace and legs, and a grey opisthosoma. They also have the same long life, ranging from 4 to 20 years. They are usually found in burrows with little silk lining, under rocks or logs, with their aptly named funnel-like webs. They are found in the coasts and highlands of southeastern Australia.
