Helcystogramma trichocyma is a moth in the family Gelechiidae.

The forewings are rather dark fuscous with the plical and first discal stigmata represented by an indistinct somewhat 8-shaped brownish spot edged with some blackish scales and then anteriorly by a fine white waved line extended to the dorsum, the second discal minute, blackish, followed by a white dot, and beneath it a more or less developed oblique white strigula about the fold.

There is also a small whitish spot on the costa at four-fifths, where a faint series of white scales crosses the wing.

Indistinct small dark marginal dots are found around the apex and termen, sometimes separated by small white marks.
