Other spiders in this genus with potentially medically significant venom include two chiefly European varieties, S. paykulliana and S. nobilis, and a species found mainly in New Zealand and South Africa, S. capensis.

However, further research on anaesthetized guinea pigs showed that the original guinea pig had actually died of shock, rather than as a result of the spider's venom. [1] In humans the bite is no more dangerous than a bee sting. [4]
