Antaeotricha ioptila is a moth of the Depressariidae family. It is found in Guyana. The wingspan is 23-24 mm. The forewings are fuscous, the posterior third of the wing suffused with pale ochreous and with a broad suffused white streak running from two-fifths of the costa to the apex, leaving the costa narrowly ochreous posteriorly. There is a yellow-ochreous median streak from the base to the middle, towards the base suffusedly widened nearly to the costa. Immediately beneath this is a whitish streak along the fold, basally widened to the dorsum, thus appearing to enclose a semi-oval dorsal blotch of groundcolour. The hindwings are rather dark grey.
