South African National Survey of Arachnida Photo Identification Guide: The Desidae of South Africa. Version 1: 1-7 (2021)

Desidae is a cosmopolitan family represented by 60 genera. Only two species are
known from South Africa. For years only a single species was known from South
Africa Desis formidabilis (O.P. Cambridge, 1890). They are intertidal hunters and
are always found in areas with a rocky shore. They are found between the lowwater
neap and high-water neap tide levels. The species is known from South
Africa to Namibia and due to its wide range it is listed as Least Concern. A second
species, Badumma longinqua L. Koch (1867) known to be invasive was only recently
reported from South Africa from two localities. It is an invasive species and
recorded from several continents. Due to wide range listed as of Least Concern.
