wingspan : male 25, female 23 mm
Euselasia sp, this male and this female look quite the same, but one comes from 11 km South of Tena and so does Jeffrey Glassberg's photo, and the other one comes from Unión Nacional Cuyabeno ; nothing could be less certain than their being male and female of the same species.
they do look like Euselasia janigena... so does the picture taken by Geoff Gallice at Yasuni.
