this butterfly was known as Hypoleria orolina orolina, and it flies in the Amazonian regions of Ecuador and Peru (d’Abrera 1984). we learn from Fabio Vitale that it now belongs to a new Genus Brevioleria, and Keith Willmott tells us it is Br. arzalia n. ssp.
but, since we created this page, we had a new name change ; from now on, but for how long ? it is Brevioleria aelia.
in the Sangay, we saw it near Puyo, where it seems not to be rare.
