Helcystogramma cyanozona is a moth in the family Gelechiidae. It was described by Edward Meyrick in 1923. It is known from southern India.[1]
The wingspan is about 10 mm. The forewings are dark fuscous with purple-blue-metallic markings and slender costal and median streaks from the base to one-fourth, some yellowish suffusion between these, some blue scales on the dorsum towards the base and a somewhat oblique-transverse blotch from the costa before the middle reaching half across wing, and a longitudinal mark on the fold beneath this. There is an almost straight transverse streak at three-fifths and a small spot on the costa towards the apex, and three on the termen. The hindwings are dark grey.[2]
