Ardozyga tyroessa is a species of moth in the family Gelechiidae. It was described by Turner in 1933. It is found in Australia, where it has been recorded from Queensland. The wingspan is about 18 mm. The forewings are ochreous-orange with sparse dark fuscous irroration, mostly in the terminal third, and markings. There is a broad outwardly oblique mark at one-third representing conjoined the first discal and plical, the second discal about two-thirds, a costal dot at one-sixth, another at three-fifths, and four smaller between this and the apex. There is also a fine interrupted terminal line. The hindwings are grey, paler towards base.
