Helcystogramma thesmiopa is a moth in the family Gelechiidae.

The forewings are violet grey with a transverse-oval blackish blotch, finely edged with white, resting on the middle of the dorsum and reaching three-fourths of the way across the wing, the anterior edge is prominent in the middle, and with the lower part of the blotch occupied (except for the margins) by a light grey irregular spot.

There is a large black finely white-edged dot in disc at three-fifths and a fine slightly curved line of whitish irroration (sprinkles) from a wedge-shaped white mark on the costa at four-fifths to the dorsum before the tornus.

There is a marginal series of white dots edged with blackish terminally around the posterior part of the costa and termen.
