Aristotelia ochrostephana is a moth of the Gelechiidae family. It was described by Turner in 1933. It is found in Australia, where it has been recorded from South Australia. The wingspan is about 9 mm. The forewings are grey with dark fuscous irroration and markings. There are costal dots at one-sixth and one-third and a fine streak on the fold from near the base, just continuous with a broad oblique streak from the fold nearly to the mid-costa. There is a discal dot in the middle touching this streak, and another discal dot at three-fourths. The apical area is mostly dark fuscous. The hindwings are pale grey.
