Crotonia is a genus of middle-derivative oribatid mites that is widely distributed in, and almost restricted to, the Southern Hemisphere. Currently only five species are reported from the Neotropical region. Herein a new species from Chile - C. blaszaki sp. nov. - is described based on the adult instar. The characters possessed by this species combine those of the so-called “obtecta”, “caudalis” and “unguifer” species-groups, which suggests that the groupings of Crotonia species should be reevaluated.
