Checklist of the spiders (Arachnida, Araneae) of the Table Mountain National Park, South Africa

Abstract

The Table Mountain National Park (TMNP) is an iconic protected area in South Africa, renowned for the high levels of plant and animal species richness and endemism. An annotated species list of spiders presently known from the TMNP is provided. The checklist was compiled from data collected from the South African National Survey of Arachnida (SANSA) database. A total of 261 species from 50 families and 167 genera are presently protected in the park. The most species-rich families are the Salticidae (31 spp.), Thomisidae (26 spp.) and Araneidae (20 spp.), while 13 families are represented by singletons. The global distribution, endemicity and International Union for the Conservation of Nature (IUCN) Red List status of each species is provided.

Conservation implications: Seventy-seven per cent of the species have a wide distribution range and are of Least Concern (200 spp.), while 31 species are Data Deficient, four species were not evaluated, and 26 species of special concern are identified. Of these, 13 spp. are Rare, three each are Critically Rare and Endangered, six are Vulnerable and one is near threatened. The TMNP protects approximately 11.4% of the total South African spider fauna and it is the type locality for 31 species. Although the TMNP and Cape Peninsula more broadly is a hotspot of endemic species for various plant and animal taxa: a proportionally small proportion of the spider species are of significant conservation concern.
