Rediscovery of Nuvol umbrosus Navás (Neuroptera, Chrysopidae, Leucochrysini): a redescription and discussion.

Tauber CA, Sosa F - Zookeys (2015)

Bottom Line: Unique aspects of the wing venation and the unusual pattern of banding on the wings support the retention of Nuvol as a valid genus within the Leucochrysini.These differences may indicate the presence of two distinct, geographically separated species within the genus.However, largely because we do not know the sexes of the earlier specimens, we are treating the differences discovered in the two female specimens as expressions of intraspecific variation.

ABSTRACT
The monotypic leucochrysine genus Nuvol was previously known from three specimens of Nuvol umbrosus Navás, collected in the Atlantic Forest region of Brazil. For many years these specimens have been missing, and the genus has remained without a modern description. Here, the species is redescribed based on two newly discovered specimens (females) from the Amazonian region. The female terminalia are relatively simple, except for the subgenitale, which is enlarged, folded into two sections, and heavily sclerotized. Unique aspects of the wing venation and the unusual pattern of banding on the wings support the retention of Nuvol as a valid genus within the Leucochrysini. There are differences between the Amazonian specimens studied here and the earlier descriptions based on specimens from the Atlantic Forest. These differences may indicate the presence of two distinct, geographically separated species within the genus. However, largely because we do not know the sexes of the earlier specimens, we are treating the differences discovered in the two female specimens as expressions of intraspecific variation.
