Opopaea deserticola
Simon, 1892
Goblin spider
Opopaea deserticola is a of goblin in the Oonopidae, first described by Eugène Simon in 1892. Originally described from Southeast Asia, this species has demonstrated remarkable capabilities and is now recognized as having one of the widest distributions among oonopid spiders. It has been to numerous regions worldwide including the Americas, Pacific islands, Atlantic islands, and Japan. The species is part of a diverse radiation of minute spiders that inhabit leaf litter and soil microhabitats, where their small size and cryptic coloration make them exceptionally difficult to detect.

One of the most broadly distributed oonopid known.
