Discovery and redescription of the true Nuvolumbrosus Navás and naming of a new Nuvol species (Neuroptera, Chrysopidae, Leucochrysini)

Examination of a newly discovered specimen of Nuvol showed that our earlier species determination of Nuvolumbrosus Navás had been incorrect and that our "redescription" of the species actually applied to an undescribed species. Here, we redescribe the true N.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 misidentified Nuvol specimens from the Amazonian region to a separate species, Nuvolsatur Sosa & Tauber, sp. nov. As a result of these actions, the genus Nuvol now contains two morphologically and geographically distinct species. In addition, the abdomens and genitalia of both sexes of Nuvol are now described (although each from a separate species).
