Habitat and ecology

The species is a free-living cryptozoic nocturnal spider that is commonly found in houses and outbuildings as well as in a wide range of other habitats. It inhabits Grassland, Savanna and Thicket biomes. The species may play a role in regulating populations of potato tuber moths, cockroaches and silver-fish.[3]

In South Africa, the species is protected in five reserves: Platberg Nature Reserve, Roodeplaatdam Nature Reserve, Tswaing Crater Nature Reserve, Sabie Sabie Reserve and Kruger National Park.[3]

Taxonomy
