Aristotelia paradesma is a moth of the Gelechiidae family. It was described by Meyrick in 1885. It is found in New Zealand. The wingspan is about 17 mm. The forewings are whitish, irregularly irrorated with light grey and with a grey suffusion along the inner margin from the base to the anal angle. There is a small blackish spot on the costa almost at the base and a black dot beneath the costa at one-fifth, and a second larger one beneath it on the fold. A thick blackish transverse somewhat oblique streak is found at one-third, reaching from beneath the costa to the fold, the margins irregular. There are also two black dots nearly longitudinally placed in the middle of the disc, and a third in the disc at three-fourths. The hindwings are grey.
