we collected this butterfly near Sucúa, it could possibly be an undescribed species (KRW pers. com.).
in 2016 David Geale took a picture of an almost identical butterfly at Arajuno (Napo). https://www.noreste.eu/en/fiche-papillon/019-Satyridae/003-Satyrinae/001-Euptychiini/025-Magneuptychia/033-undescribed+-+2/_
