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.
