Majeorona aper (Walker, 1850)

Fidicina aper Walker 1850: 87 . (Cayenne, French Guiana)

REMARKS.—This is the largest of the Ecuadorian Majeorona species with body lengths of about 48 mm and wing spans of more than 120 mm. The basic brown and piceous coloration, the anterior extension of the postclypeus when viewed from the dorsal side and the fore wings have infuscation on the radial and radiomedial crossveins which easily distinguish it from M. truncata Goding, 1925 .

DISTRIBUTION.—The species is known from Brazil, Colombia, Ecuador, French Guiana, Nicaragua, and Panama (Metcalf 1963a; Sanborn 2011a; 2013; 2018c; Maes et al. 2012; Sanborn & Maes 2012) with recent records reported for Peru (Sanborn 2020b). Goding (1925) reported the species from Posorja, Guayas province and Macas, Morona Santiago province.
