Comments.

This species is known from Brazil (Roraima) and Colombia (Departaments of Boyacá, Cundinamarca, Putumayo, and Tolima). Camargo and Moure (1996) examined a single female specimen from Tolima, which had a low carina on the vertex, in comparison to the Brazilian specimens; they suspected of a differentiated population of this species in Colombia. Gonzalez and Sepúlveda (2007) expanded the distribution range in Colombia, noting that all records came from the Andean region (as in this new record) as well as minor differences in the wing color, namely the forewing dusky apically. It is likely that the Colombian specimens are actually a distinct species given these subtle differences but more importantly their allopatric distribution; however, more records as well as the study of males of both species are necessary to test this hypothesis.
