3 genera, 28 species

The Archaeidae are a spider family with 25 described species in three genera. Commonly known as assassin spiders, they are also known as pelican spider stemming from their specialised anatomy: they have elongated chelicerae (jaws) and necks for catching other spiders.


Archaeidae occur in South Africa, Madagascar and Australia.

Assassin spiders[edit]

Assassin spiders, also known as the Spidsnuck, are a group of spiders of the families Archaeidae and Mecysmaucheniidae, which are extremely unusual in that they have "necks," which can be very long and slender or short and fat. Archaeids prey only upon other spiders, while mecysmaucheniids seem to be generalists. Assassin spiders were first known from 40 million year old amber fossils, which were found in Europe in the 1840s, and were not known to have living varieties until 1881, when the first living assassin spider was found in Madagascar. They are native to Australia, South Africa, and Madagascar, with the sister family Mecysmaucheniidae occurring in Southern South America and New Zealand. They range in size from 2-8 mm.
