﻿AbstractExamination of a newly discovered specimen ofNuvolshowed that our earlier species determination ofNuvolumbrosusNavás had been incorrect and that our “redescription” of the species actually applied to an undescribed species. Here, we redescribe the trueN.umbrosus, based on a newly discovered male specimen. This specimen closely resembles Navás’ description, and it was collected from the Atlantic Forest as was the original type specimen. In addition, we assign the previously misidentifiedNuvolspecimens from the Amazonian region to a separate species,NuvolsaturSosa & Tauber,sp. nov.As a result of these actions, the genusNuvolnow contains two morphologically and geographically distinct species. In addition, the abdomens and genitalia of both sexes ofNuvolare now described (although each from a separate species).
