Idiosoma nigrum, also called Black rugose trapdoor spider, occurs only in south-western Australia, in dry woodlands east of the Darling Scarp and north to Moore River.
An example can be seen in the mygalomorph spider Idiosoma nigrum (Black Rugose Trapdoor Spider), which protects itself in its burrow by positioning itself so as to block the burrow with its abdomen, which is unusually hard.
