Kertomesis acatharta is a moth in the family Autostichidae. It was described by Edward Meyrick in 1911. It is found in India.[1]
The wingspan is 13–14 mm. The forewings are whitish ochreous, irregularly marbled with light purplish-grey suffusion irrorated (sprinkled) with black. The dark colouring forms a basal patch containing two short ochreous-yellow streaks from the base and limited by a pale yellowish-tinged line from before one-third of the costa to two-fifths of the dorsum, somewhat angulated and tending to be interrupted on the fold. It also covers the dorsal three-fifths of the rest of the wing, including two or three small yellowish spots beyond the middle, and extending as a fascia to the costa at three-fourths, and along the termen to the apex. There is a small dark spot on the costa before the apex. The hindwings are grey.[2]
