Study of Spiders
Research in the Arachnology Department is concentrated on the medically important spiders in the genus Latrodectus (Theridiidae), the genera Cheiracanthium and Cheiramiona (Eutichurgidae) and the genera Loxosceles and Sicarius (Sicariidae) of the Afrotropical Region. Other research projects include studies on spider biodiversity and rare forest spiders of the genera Eriauchenius and Afrarchaea (Archeaidae), the distribution of Opiliones in southern Africa and the taxonomic revision of the South African Pseudoscorpionida.

Russian visitor to the spider collection

Dr Galina Azarkina visited the Arachnology Department in November 2015 to study jumping spiders (Salticidae). She is the curator of the Arachnida Collection at the Siberian Branch of the Russian Academy of Sciences, Novosibirsk.
Museum Scientist
Jan Andries Neethling MSc ja.neethling@nasmus.co.za
Jan registered for B.Sc Microbiology at the University of the Free State in 2006, obtaining the degree with distinction in 2009. In 2010 he registered for third year B.Sc Entomology, obtaining distinctions in all the registered subjects and was consequently accepted into the Honours program at the Zoology and Entomology department in 2011 where he specialised in Arachnid taxonomy, but also did courses in Forensic Entomology and Plant-Insect Interactions.
At the end of 2011 he obtained his Honours (cum laude) with his thesis: “Effect of moon phases on the activity patterns of trapdoor spiders, scorpions and solifugids at the Free State National Botanical Gardens”.
He recently (2015) obtained his Master of Science (cum laude) with his thesis: “Revision of the South African Geogarypidae (Arachnida: Pseudoscorpiones)”, which represents the first holistic taxonomic study of a South African pseudoscorpion family, taking both molecular and morphological characters into consideration.
He is currently busy with the taxonomic revision of the South African Pseudoscorpionida fauna.

Free State Spider Survey
Why are we conducting a survey?
Spiders are extremely important animals. They occur in vast numbers and are the primary predators of the equally common insects. Because they are so common, they are often encountered by people and we receive many enquiries requesting information about spiders. Many people needlessly fear spiders, as most are harmless to humans.
Despite their importance and abundance, not much is known about the spiders of the Free State. There are no truly comprehensive collections of spiders from this area, as most collectors concentrated on the eastern part of South Africa.
Spiders are often missed; they are overlooked scientifically and often despised or feared by the public. However, spiders play a critical role in the web of life we so often take for granted. More information about spiders is needed, especially those in our own backyards, if we are to ensure their future and the health of our environment.
How will the Free State Spider Survey work?
In order to conduct a large-scale survey of spiders, we need the help of the public. We request the public to collect spiders in their homes and gardens, fill out a simple data sheet about their collection and send or bring them to the National Museum. Our experts will identify the specimens, fill out a collecting record, and accession them in the collection. If requested, the identity of the spider will be sent to the collector. Spiders collected in the survey will be used to create a database about the distribution and abundance of the species. Results will be reported on the web site. Other arachnids, such as scorpions, may also be submitted.
Disclaimer: The Museum appreciates your assistance in this scientific project. If you have any concerns about participating, we suggest you do NOT participate. The Museum cannot be responsible for the treatment of bites or for any injury or illness resulting from the project.

The Arachnology collection started as a subsection of the Entomology Department in 1982, but became a full department in 2003. The collection currently comprises ca. 52 000 specimens. These are mostly arachnids (excluding Acari), but other invertebrates are also included to a lesser extent (Myriapoda, Mollusca and Crustacea).
Amblypygi | 6 |
Araneae | 42 120 |
Opiliones | 3 314 |
Pseudoscorpiones | 533 |
Scorpiones | 1 058 |
Solifugae | 1 931 |
Other | 3 468 |
52 430 |
The specimens are almost all from the Republic of South Africa and have been collected from all over the country.
