The Perrin's cave beetle is an extinct freshwater beetle from France.[1] It and Siettitia ayenionensis are the only two species in the genus Siettitia.
This subterranean species was discoloured, its sensory silks were well developed and the eyes were extremely reduced and probably functional. The tracheae of its wing-cases (elytra) were well developed and it absorbed dissolved oxygen through its cuticle.[2]
