Genus Opopaea Simon, 1892

Remarks. Opopaea is one of the most diverse genera in the family Oonopidae; the genus currently comprises 187 species distributed in tropical regions (World Spider Catalog 2023). The genus was initially established based on the type species O. deserticola from Saint Vincent Island. Opopaea spiders are typically small to medium-sized (body length:1.0– 2.4 mm) and can be found in a variety of habitats, including litter layers, dead wood, and forests (Andriamalala & Hormiga 2013). Members of this genus are characterized by several unique features: entirely sclerotized male palps with enlarged patella originating sub-basally from the palpal femur, lateral striations on the carapace, and the dorsum and venter of the abdomen completely covered with scutum (Andriamalala & Hormiga 2013).
