摘要

The South African National Survey of Arachnida (SANSA) was initiated to make an inventory of the arachnid fauna of South Africa. Various projects are in progress to prepare inventories of the spider fauna of the different biomes and provinces of SouthAfrica. Between 1996 and 1997 ground-dwelling spiders were sampled with pitfall traps from different stands of coastal dune forest at Richards Bay, KwaZulu-Natal. The forest biome, of which the coastal dune forest forms part, is the smallest floral biome in Southern Africa, covering less than 0.25% of the surface area. This was the first quantitative survey of spiders of coastal dune forest at Richards Bay. Twenty-five families represented by 39 genera and 48 species were recorded. The Lycosidae was the most abundant family (589 individuals), representing 71% of all the spiders sampled, followed by the Ctenidae (102) with 12% and the Thomisidae (23) with 3%. The most abundant spider species was an undescribed lycosid species, followed by Ctenus gulosus Arts, 1912 (Ctenidae). The Lycosidae was the most species rich family (7) followed by the Corinnidae (6), while 13 families were represented by single species. Forty-eight species were new distribution records for the Richards Bay area.
