Ricinulei

Ricinulei is a small order of arachnids. Like most arachnids, they are predatory; eating small arthropods. They occur today in west-central Africa (Ricinoides) and the Americas (Cryptocellus and Pseudocellus) from Brazil to southern Texas, where they inhabit either leaf-litter or caves. As of 2022, 103 extant species of ricinuleids have been described worldwide, all in the single family Ricinoididae. Due to their obscurity they do not have a proper common-name, though in academic literature they are occasionally referred to as hooded tickspiders.

Ricinoides is an arthropod genus in the family Ricinoididae, first described by Henry Ewing in 1929.
