Imma metriodoxa is a moth in the family Immidae. It was described by Edward Meyrick in 1906. It is found on Sumbawa in Indonesia.[1]
The wingspan is about 22 mm. The forewings are fuscous, finely sprinkled with ochreous whitish and with a small indistinct ochreous-whitish spot on the costa before the middle and a moderate dark fuscous discal dot at three-fifths, as well as a slender ochreous-whitish oblique streak from the costa at two-thirds, angulated above the middle and then proceeding as a faint sinuate line to the tornus. There is an ochreous-whitish almost apical dot and an irregular terminal line of dark fuscous suffusion. The hindwings are fuscous with a suffused submedian streak which is paler and ochreous tinged.[2]
