South African National Survey of Arachnida Photo Identification Guide: The Amaurobiidae of South Africa 2020 version 1: 1-26

The Amaurobiidae occurs worldwide and is known from 50 genera and 276 species. The family comprises several subfamilies, and one, Macrobuninae, is known from South Africa where it is represented by five genera and 16 species. All of them are South African endemics.  In a study by Almeida-Silva (2013) on the rest of the Macrobuninae, seven new genera were proposed but must  still be described. Of the sixteen 16 known species  three species are listed as Least Concern but for the majority, the status remains obscure and is Data Deficient. Some more sampling is needed to collect both sexes and to determine the species range. Only two species of amaurobiids are of special concern. The numbers of Chumma inquieta Jocqué, 2001 are declining due to ongoing loss of its coastal habitat to housing developments and qualifies as Endangered under criterion B. Chumma striata Jocqué & Alderweireldt, 2018 known from both sexes, is regarded as Rare due to the species having a small restricted distribution range (< 500 km2).
