Udubidae is a family of araneomorph spiders. Most of its members were previously classified under the now-discredited family Zorocratidae. This family is characterized by its distinct phylogenetic placement within lycosoid spiders, with some genera forming a clade separate from the type genus Zorocrates.

About Udubidae
Udubidae is a taxonomic family of araneomorph spiders. This family was established to group certain genera of spiders that were formerly classified under the family Zorocratidae, a classification that is no longer recognized by the scientific community.
Phylogeny and Taxonomy
Research into the evolutionary relationships of lycosoid spiders has led to the reclassification of several genera. Studies indicated that the genera previously grouped in Zorocratidae did not form a single, monophyletic group. Some of these genera, including Raecius, Uduba, and Zorodictyna, were found to form a distinct clade, separate from genera like Zorocrates and Zoropsis. This phylogenetic understanding necessitated the creation of a new family for the members that did not align with the revised placement of the type genus Zorocrates. The family Udubidae was proposed by Griswold and Polotow, with Uduba serving as the type genus. The World Spider Catalog currently recognizes Udubidae as a valid family.
Genera and Species
As of January 2026, the Udubidae family is comprised of six genera. Across these genera, a total of 58 species have been described. The specific genera and their constituent species are subject to ongoing taxonomic research and cataloging.

Frequently Asked Questions
What is Udubidae?
Udubidae is a taxonomic family of araneomorph spiders. This classification was established for genera that were previously grouped under the family Zorocratidae, which is no longer considered a valid taxonomic unit.
How many genera and species are in the Udubidae family?
As of January 2026, the Udubidae family encompasses six genera. In total, there are 58 described species within this family.
What was the previous classification for spiders now in Udubidae?
Most of the spiders that now constitute the Udubidae family were previously classified under the family Zorocratidae. However, Zorocratidae is no longer recognized as a valid family in spider taxonomy.
Who proposed the name Udubidae?
The name Udubidae was proposed by researchers Griswold and Polotow. This new family name was established to accommodate genera that no longer fit within other taxonomic structures after the dissolution of Zorocratidae.
