Salbia nebulosalis is a moth in the family Crambidae. It is found in Costa Rica.[1]
The wingspan is about 21 mm. The wings are whitish, with fuscous brown lines. The forewings are thinly clouded with brown and the base is shaded with brown. There is a slightly curved antemedial line, outwardly shaded with brown and there is a line on the discocellular, as well as a medial line from vein 2 to the inner margin. The postmedial line is slightly incurved from the costa to vein 6, and from 6 to 2, where it is slightly upbent towards the discocellular. The outer margin is broadly fuscous brown, expanding below vein 2 to the inner margin. The hindwings have an antemedial shade and a spot at the end of the cell and a medial line from below the cell to the inner margin. The postmedial line expands from vein 2 to the anal angle and there is a subterminal broken line from a large apical space to the postmedial at vein 2. The terminal line does not reach the anal angle.[2]
