Helcystogramma armatum is a moth in the family Gelechiidae. It was described by Edward Meyrick in 1911. It is known from northeastern India.[1]
The wingspan is 10–11 mm. The forewings are rather bright fulvous with bluish-leaden-metallic markings edged with blackish scales and with a streak from the base along the costa to one-third, thence obliquely across the wing to two-thirds of the dorsum, where it meets a slightly curved rather narrow fascia from three-fifths of the costa. There is a subdorsal streak from the base to two-fifths and a small white mark on the costa beyond the postmedian fascia. The posterior area beyond this fascia is wholly black, except for an irregular blue-leaden-metallic fascia close before the termen, leaving a fulvous black-edged terminal line. The hindwings are blackish fuscous.[2]
