Argyronetidae is a family of araneomorph spiders that was formally redefined in 2025, having previously been subsumed under the family Dictynidae. While earlier attempts to establish Argyronetidae as a distinct family were unsuccessful, the current classification recognizes its unique characteristics. Members of this family are predominantly found across Asia, Europe, and North Africa, with a notable presence of six genera in North America.

About Argyronetidae
What is Argyronetidae?
Argyronetidae is a family of araneomorph spiders. The family's current taxonomic status was established in 2025, following a redefinition by Montana et al. Prior to this, the genera now comprising Argyronetidae were largely classified under the broader family Dictynidae. Although earlier attempts to recognize Argyronetidae as a separate family were not widely accepted, the 2025 redefinition has solidified its place in spider taxonomy. It is even suggested that one of its genera, Argyroneta, may represent its own subfamily.
Distribution and Genera
Members of the Argyronetidae family are found across a wide geographical range. They are predominantly located in Asia, Europe, and North Africa. Furthermore, six distinct genera of Argyronetidae have been identified in North America. The genus Mizaga is notable for being endemic to Senegal, meaning it is found exclusively in that region. Another genus, Paratheuma, has a worldwide distribution.
As of October 2025, the Argyronetidae family is recognized to include twelve genera. The specific characteristics, behaviors, and ecological roles of these genera continue to be areas of study within arachnology.

Frequently Asked Questions
What is Argyronetidae?
Argyronetidae is a family of araneomorph spiders. It was formally established as a distinct family in 2025 after previous attempts to separate it from Dictynidae were unsuccessful. The family's classification has been refined to include specific genera.
Where are Argyronetidae spiders found?
Spiders belonging to the Argyronetidae family are mainly distributed across Asia, Europe, and North Africa. Additionally, six genera within this family have been found in North America, indicating a widespread geographical presence.
What is the taxonomic history of Argyronetidae?
The family Argyronetidae was first proposed by Tamerlan Thorell in 1869. However, for a significant period, all of its genera were classified under the family Dictynidae. It was only in 2025 that the family was redefined and re-established as a distinct taxonomic unit.
Are there any endemic species within Argyronetidae?
Yes, the genus Mizaga, which is part of the Argyronetidae family, is endemic to Senegal. This means it is found naturally in that specific geographic region and nowhere else in the world.
