11; see text Zephyrarchaea is a genus of Australian assassin spiders first described by Michael Gordon Rix & Mark Harvey in 2012 for nine new species and two that were formerly placed in the genus Austrarchaea.

[2] The name is based on the Latin zephyrus, meaning "west wind", referring to the western distribution in Australia and a preference for windy, coastal habitats by some species.

[1] They are distinguished from Austrarchaea by a notably shorter carapace, the distribution of long hairs (setae) on the male chelicerae, and by the shape of the conductor of the male palpal bulb.

The Australian Alps may be a barrier dividing the two genera.

[2] As of April 2019[update] the genus contains eleven species:[1]
