Holarchaea is a genus of South Pacific araneomorph spiders in the family Anapidae, and was first described by Raymond Robert Forster in 1955. [2] As of May 2019 [update] it contains only two species, H. globosa and H. novaeseelandiae, but there may still be undescribed species in New Zealand. [3]
These spiders are shiny black to beige, and grow up to 1.5 millimetres (0.059 in) long. [3] They are one of few spider taxa that do not have venom glands. [4]
They are known only from the forests of Tasmania and New Zealand, where they live in many microhabitats that regularly have high humidity. [3] [1] Originally placed with the assassin spiders, it was moved to its own family, Holarchaeidae, in 1984, [5] and Holarchaeidae was synonymized with Anapidae in 2017. [6]
