Ixamatus broomi is a species of mygalomorph spider in the Microstigmatidae family. It is endemic to Australia. It was described in 1901 by British arachnologist Henry Roughton Hogg.
The species occurs in south-eastern Queensland and north-eastern New South Wales, in tall open and closed forest habitats, including the border ranges and the Lamington Plateau. The type locality is Hillgrove in the Northern Tablelands.
The spiders are terrestrial predators. They construct shallow burrows in humus and tubular silk shelters in logs.
