Genus: Steatoda
Species: S. capensis
Scientific name: Steatoda capensis
Common name: False katipo spider, Black cobweb spider, False widow spider.
They are a spider with a body length up to 7 mm.
Originating from South Africa it is now commonly found in New Zealand. They can be found
under logs or in any dark places. It is much more common than the katipo. They catch small crawling insects.
Unlike the katipo the bite of the false katipo spider is not harmful, but it stings and the area aches for an hour. It may also cause headaches or nausea. Small blisters may occur around the bite site.
