Ardozyga thyrsoptera is a species of moth in the family Gelechiidae.

The forewings are pale fuscous, irregularly mixed with darker and with a pale basal patch, its edge running from two-fifths of the costa to the dorsum near the base, enclosing small dark fuscous costal spots at the base and one-fifth.

Beyond this a transverse dark fuscous spot from the costa, terminating beneath in two divergent slender partially white-edged arms, terminated and connected on the fold by a blackish streak produced anteriorly to the basal patch.

There is a short black elongate mark in the disc above the middle and a rather ill-defined black longitudinal streak from the middle of the disc to the termen beneath the apex, with an interrupted branch to the costa above the apex and a cloudy white dot resting on this representing the second discal stigma.

There is also a series of small dark fuscous spots separated by whitish dots on the posterior half of the costa and an interrupted whitish dark-edged terminal line.
