About Melloinidae

Melloina

Melloina is a genus of spiders characterized by their distinctive "bald legs." First described by Paolo Marcello Brignoli in 1985, this genus now comprises five recognized species. These arachnids are native to a specific region in South America, being found in Panama, Colombia, and Venezuela.

Taxonomy and Classification

Historically, spiders within the Melloina genus were classified under broader families such as Theraphosidae and Paratropididae. However, a significant taxonomic revision in 2025 led to the establishment of a dedicated, monotypic family for this genus: Melloinidae. This elevation signifies a unique evolutionary lineage for Melloina spiders.

As of early 2026, five species have been formally described within the Melloina genus. Their geographic range is limited to the South American countries of Panama, Colombia, and Venezuela. Further research may uncover additional species or expand the known distribution of those currently identified.
