Arachnids (Chelicerata: Arachnida) were collected in the Ndumo Game Reserve (Maputaland, South Africa) during 11 collecting trips in the period 2000–2006. Sampling was undertaken by various methods in eight broad habitat types: Acacia tortilis savanna; Acacia xanthophloea (fever tree) forests; deciduous broadleaf woodland; Ficus (wild fig tree) forests; floodplain vegetation; riparian forest; sand forest; and subtropical bush. In total, 457 species of arachnids were collected, representing six orders, 59 families and 240 determined genera. The most diverse order was the Araneae (46 families, 431 spp.), followed by the Pseudoscorpiones (6 families, 12 spp.), Scorpiones (3 families, 8 spp.), Opiliones (2 families, 3 spp.), Solifugae (1 family, 2 spp.) and Amblypygi (a single species). The most diverse families all belonged to the Araneae: Salticidae (82 spp.), Thomisidae (56 spp.) and Araneidae (38 spp.). The spider diversity is the highest recorded from any protected area in South Africa so far, and represents approximately 22 % of the country’s spider fauna. The habitat and guild associations of each species are provided.

The thick-shelled clam Meretrix morphina, previously referred to as Meretrix meretrix, now occurs in the west Indian Ocean region, along the eastern seaboard of Africa, from the Red Sea to the Mlalazi Estuary, close to the Tugela River. Its presence in South Africa is only of recent recording. Meretrix morphina was detected for the first time in Lake St Lucia in 2000. The population declined and was not detected from 2005 until 2011, most likely as a result of a severe drought that resulted in widespread desiccation and hypersalinity in the lake. The system then experienced increased freshwater input resulting in lower salinities from 2011 until 2014, during which time M. morphina reappeared and their population gradually increased. In 2015, M. morphina became abundant in St Lucia, attaining unprecedented densities of 447 ind./m2. Biomass, expressed as a fresh weight, varied in the different basins of St Lucia, ranging from 195 g/m2 at Lister’s Point to 1909.8 g/m2 at Catalina Bay. However, in 2016, when drought conditions returned, M. morphina disappeared. This species appears to thrive under brackish salinities and high temperatures. It is able to establish large populations with high biomass and can become dominant. However, M. morphina is sensitive to desiccation and hypersaline conditions. This clam has substantial commercial value and is exploited along the African east coast, particularly in Mozambique. In future, it may feature more prominently in South African estuaries. However, the ecology of M. morphina is still largely unknown.
