Saddle-legged Trapdoor Spiders

Family Ctenizidae, genus Conothele

Saddle-kneed trapdoor spider, Ctenizidae, Conothele, female


Their common name comes from the saddle-shaped dent in the middle of the third leg. This is used by the spider to lock itself firmly against the walls of its burrow.

Diversity & distribution

They tend to be found in warmer parts of Australia, from the beach on rainforest trees to the hottest parts of central Australia.

The family occurs through tropical parts of the world including many islands.


These spiders build plug doors on their burrows.


These are relatively rare spiders and no bites have been recorded.
