'''''Tartarus''''' is a [[genus]] of spiders in the family [[Stiphidiidae]].<ref name="fix1" /> All four described species are found in cave systems of [[Western Australia]].<ref name="fix2" /> These are located in the [[karst]] area of the [[Nullarbor Plain]]. They are likely [[Relict (biology)|relict]] species from a time when the region was much more humid, given the fact that the other members of the family [[Stiphidiidae]] in Southern Australia live in forests.

==Names== The genus name is derived from [[Tartarus]], a place in the underworld of [[Greek mythology]], even lower than [[Hades]]. All four species take their common names, and the specific epithet, from the caves in which they were first collected.

''Tartarus murdochensis'' and ''Tartarus thampannensis'' are both commonly called [[Murdoch, Western Australia|Murdoch]] sink cave spider, ''Tartarus nurinensis'' is also known as the Nurina cave spider.
