Ardozyga amphiplaca is a species of moth in the family Gelechiidae. It was described by Edward Meyrick in 1932. It is found in New Guinea. The wingspan is 11-12 mm. The forewings are dark grey with a light ochreous-yellow basal patch extending on the costa to one-fourth and on the dorsum to near the middle, the edge slightly convex, and with a small dark grey mark on the costa near the base. There is a broad light ochreous-yellow fascia crossing the wing near and parallel to the termen, the anterior edge rather convex in the disc, the posterior irregular. The hindwings are grey, somewhat darker posteriorly.
