dc.description.abstract The Ricinulei Thorell, 1876, or “hooded tick-spiders,” are among the least studied arachnid orders. Knowledge of ricinuleid diversity has been slow to accumulate because these arachnids are underrepresented in biological collections. Despite an increase in the pace of new species descriptions in recent decades, the species richness of the order probably remains vastly underestimated. Large areas in some of the world’s most biodiverse countries are without a single record for the order, hence new records invariably turn out to be new species. The present contribution describes four new species of the mostly South American genus Cryptocellus Westwood, 1874: Cryptocellus canutama, sp. nov., and Cryptocellus jamari, sp. nov., from Brazil; Cryptocellus islacolon, sp. nov., from Panama; and Cryptocellus macagual, sp. nov., from Colombia. Additionally, a new diagnosis and description are provided for Cryptocellus leleupi Cooreman, 1976, long considered a nomen dubium. The known locality records of the five species and their putative relatives are mapped. The present contribution raises the number of Cryptocellus species to 45 and the number of extant species of Ricinulei to 101. en_US
