Abstract

There are eleven genus-group names available in the arachnid Order Ricinulei Thorell, 1876 by the end of 2025. Ten of these refer to currently accepted genera: three extant and seven extinct. One genus-group name is in synonymy. Six (60%) of the currently accepted genera were described since 1950. Ricinulei includes 127 currently accepted species-group names (104 extant species and 23 extinct species) and two nomina dubia. The phylogeny and suprageneric classification of the order remain poorly understood and some of the extant genera appear to be paraphyletic.
