Measurements: Wing span 20.5–22.5 mm in males (n=10), length of antennal pectinations reaching 0.4–0.42 mm in Costa Rica series and 0.5–0.52 in moths from Ecuador.

Diagnosis: The species is characterized by smaller, delicate male genitalic armature and small, simple aedeagus (length 1.20–1.25 mm) lacking cornutus ( Figs. 31–33 ).

Description: Forewing medial and postmedial lines fused X-shaped in anal area, separating the yellow tornal blotch and a yellow line proximal to the medial line ( Fig. 6 ). Hindwing submarginal field greyish brown, ample marked yellow at costa. Hindwing below with two grey blotches in terminal area. Forewing below with two distinct lines at middle of the anal area; the tornal spot 8-shaped. Fresh specimens with wings underneath tinted reddish. Male genitalia of relatively delicate build, aedeagus not sack-shaped but short, flat and lacking apical spine. Sternite A8 not sclerotized distally.

Biology: Confined to primary rain forests on lowlands and low hills.

Etymology. The specific name is from the locality name Motilonia in Costa Rica. Gender feminine.

Distribution: Nicaragua, Costa Rica; Ecuador.
