Ardozyga deltodes is a species of moth in the family Gelechiidae. It was described by Lower in 1896. It is found in Australia, where it has been recorded from Victoria and New South Wales. The wingspan is 15-19 mm. The forewings are pale ashy-grey, densely irrorated (speckled) with dark fuscous, with bronzy-purplish reflections. In males, there is a small ochreous-white basal spot, while there is a pale ochreous basal dot in females. There are ochreous-white dots on the costa near the base, and at one-fourth of the dorsum, more ochreous in females. The stigmata are blackish-fuscous, the plical obliquely beyond the first discal, both these followed by ochreous-whitish dots. There is also an ochreous-whitish dot on the middle of the costa and an ochreous-yellow blotch from the tornus reachin
