Etymology.

This species is dedicated to the Ministerio del Ambiente y Energía (MINAE) of the government of Costa Rica in recognition of its 28 years of continuous and widespread support for the survival and conservation of the wild biodiversity of Costa Rica.

Diagnosis.

Symmerista minaei differs from Symmerista luisdiegogomezi on: dorsal FW ground color beige and light brown, square mark creamy near the reniform spot; beige mark in the apex; fringe beige yellow; dorsal HW beige. Male genitalia: T8 anterior margin slightly concave, posterior margin finely serrated with a window in the center; St8 lateral margins wide at the base, narrow to posterior margin, anterior margin concave, slightly sclerotized with a short projection in the center, posterior margin with robust projections, highly sclerotized on each side, with blunt apices, a little dome in the middle of the posterior margin; length of the phallus 3.3 mm, proximal part of phallus tube wide at base, distal part of phallus tube robust, sclerotized, with a tubular lateral projection rounded apex with the distal nipple; proximal part of the vesica with a ventral scobinate patch, distal part of the vesica bulbous. Female genitalia: Anterior and posterior apophyses the same size, long an slender; DB sclerotized; CB rounded, membranous and pleated; posterior margin of postvaginal plate sclerotized, slightly irregular, inverted V-shape.

Male genitalia (Figs 21-24) - T8 wider than long, anterior margin slightly concave, posterior margin finely serrated with a window in center; St8 lateral margins wide at base, narrow to posterior margins, anterior margin convex, slightly sclerotized with a short projection in center, posterior margin concave with a pair of short projections, these sclerotized with blunt apices, a small setose dome in middle of posterior margin (Fig. 23); valva membranous, mildly pubescent, margin of sacculus slightly serrated, costa with straight margin with a distal protuberance close to apex; valva with a triangular spine-like process; tegumen narrowed dorsally; uncus plate slightly concave, somewhat helmet shaped, dorsal surface rough, pubescent, ventral surface smooth with sparse pubescence, socii long, wide, pubescent at bases, narrow and flattened at apex, form s-shaped; vinculum slightly sclerotized (Figs 21, 22); length of phallus 3.3 mm, proximal part of phallus tube wide at base, distal part of phallus tube robust, sclerotized, with a tubular lateral projection rounded apex with distal nipple; proximal part of vesica with a ventral scobinate patch, distal part of vesica bulbous (Fig. 24).
