Antaeotricha juvenalis is a moth in the Depressariidae family. It was described by Meyrick in 1930. It is found in Brazil. The wingspan is about 17 mm. The forewings are shining white with the markings fuscous. There is a small cloudy spot beneath the costa at one-fifth, and one on the dorsum at one-fourth. There is a strong dash in the disc before the middle and a triangular blotch on the dorsum beyond the middle, reaching nearly half across the wing, as well as a slightly curved longitudinal line from the disc above the middle to meet a very oblique line from beneath the costal edge at three-fifths, which is curved around beneath to the posterior angle of a subquadrate spot on the tornus, its anterior angle emitting a linear projection. Two small oval dark fuscous spots are found above t
