1 genus, 2 species

Holarchaea is a spider genus with only two described species as of September 2016,[1] although there may be undescribed species from New Zealand.[2] It is the only genus in the family Holarchaeidae.[3]

They are only up to 1.5 mm in size and shiny black to beige in color.[2] Together with the Uloboridae and possibly the Mesothelae, they are one of three taxa of spiders known to lack venom glands.

Distribution and habitat[edit]

Holarchaeid spiders are known only from the forests of Tasmania and New Zealand, where they live in microhabitats with consistently high humidity.[2]
