The katipo, Latrodectus katipo, is an endangered species of spider native to New Zealand. A member of the genus Latrodectus, it is related to the Australian redback spider, and the North American black widow spiders. The species is venomous to humans, capable of delivering a dangerous spider bite. Katipo is a Māori name and means "night-stinger". It is a small to medium-sized spider with the female having a distinctive black body with a white bordered red stripe on its back. North of 39° 15' S females do not have a red stripe and are all black. The male is much smaller than the female and quite different in appearance, being white with black stripes and red diamond shaped markings. Katipo have a narrow habitat, being only found living in sand dunes close to the seashore. They range throughout most of coastal New Zealand, but are not found at the southernmost regions. Spinning an irregular tangled web amongst dune plants or other debris, they feed mainly on ground dwelling insects. (Full article...)
