Cteniza sauvagesi is a trapdoor spider in the family Ctenizidae. It can reach 20 millimetres (0.79 in) in body length, and is dark and sturdy, with a shining head. The species occurs in the Mediterranean region, mainly on the large islands of Corsica and Sardinia. Their burrows are lined with gossamer, more so than with Nemesiidae spiders. The cork-like lid can have a diameter of up to one cm. When the spider notices prey (probably by detecting vibration), it lunges out, grabs it and retreats immediately. The spider always stays inside its burrow with its hindlegs, in order not to lock itself out.

The male wanders about, searching for a mate. If he finds one, he will quaver on her lid with his legs. The female will then appear.
