Paectes fuscescens
(Walker, 1855)
Paectes fuscescens is a in the Euteliidae, originally described by Francis Walker in 1855 under the basionym Edema fuscescens. The occurs across a broad Neotropical range from Central America through South America to Paraguay and Brazil, including the Antilles. It belongs to a that has been subject to recent taxonomic revision, with cryptic identified based on genital rather than external wing patterns.

Identification
Identification of Paectes fuscescens requires examination of genitalic characters, as external wing patterns within the Paectes arcigera are highly similar and unreliable for distinguishing . Male and female genitalia show consistent diagnostic differences that separate this species from .
