Helcystogramma sertigera is a moth in the family Gelechiidae.

The forewings are glossy blue leaden and with a streak of blackish suffusion on the fold from one-fifth to near the middle of the wing.

There is a small yellow-ochreous spot in the disc at two-fifths, from which a streak of blackish suffusion runs to a broad irregular-edged yellow-ochreous transverse fascia at three-fourths, preceded by blackish suffusion and including an irregular blue-leaden blotch.

The terminal area beyond this is chestnut brown, with three minute yellow-whitish dots on the costa.
