Zelosyne olga is a moth in the family Gelechiidae. It was described by Edward Meyrick in 1915. It is found in Guyana.[1]
The wingspan is 8–10 mm. The forewings are bronzy brown with two broad snow-white fasciae edged with black, the first extending on the dorsum from near the base to the middle, gradually narrowed upwards, the second at about two-thirds, narrowed on the costa, the anterior edge convex on the upper half, the posterior somewhat irregular. There is a suffused orange patch on the lower part of the termen and three or four dashes of blackish sprinkles on the veins above this, confluent on the apical margin. A fine oblique white strigula is found from the costa at three-fourths. The hindwings are grey, darker on the veins and towards the apex and termen, the basal half hyaline (glass like) except the veins and a streak through the middle of the cell.[2]
