Comments. This species was originally described by Klapálek (1922) based on material collected in Santarém. The variation in wing pigmentation observed in morphotypes 1 and 2, as cited by Menezes et al. (2020), corresponds to the redescription of the species by Ribeiro & Rafael (2009), who noted a more infuscated forewing in males and variation in the shape of the r and r-m veins in females. The pronotum of the male matches the description of variant 1 provided by Menezes et al. (2020) and Ribeiro & Rafael (2009). The subgenital plate of variant 1 also follows the pattern described by Ribeiro & Rafael (2009). All specimens of this species examined in this work are teneral. First record for the municipality of Oriximiná.
