Stenorista fortunata is a moth in the family Crambidae. It was described by Schaus in 1912. It is found in Costa Rica.[1]
The wingspan is about 22 mm. The forewings are whitish, the basal third of the costa and cell shaded with brown. There are yellow-buff shades basally below the cell and a broad antemedial, irregular, fuscous shade, as well as a dark brown medial line, followed in the cell by a fuscous shade and a yellow-buff spot, outwardly limited by a dark curved line. There is also a dark line from the cell along vein 2, then wavy to the inner margin. Across the discocellular runs a yellow-buff, incurved crescent which is finely edged with brown. The points of this crescent are semi-connected by small brown and yellowish spots beyond the cell, which form part of a postmedial punctiform line. There is a broad subapical fuscous-brown shade along the costa to the marginal line at vein 5. The latter is also fuscous brown. Both are edged inwardly and along the termen with yellow-buff. The veins are partly shaded with yellow-buff. The hindwings have a marginal line, which is broader from below the costa, upbent along the inner margin and coalesces with a spot below vein 2. There is a fine downbent postmedial line and there are yellow shadings along the marginal line, which is irrorated with silvery-grey scales. A terminal dark line and points on are found on both wings.[2]
