Antaeotricha pyrgota is a moth in the Depressariidae family. It was described by Meyrick in 1930. It is found in Brazil. The wingspan is 11-12 mm. The forewings are white with a dark grey oblong blotch occupying the anterior half of the dorsum and reaching half across the wing, the upper posterior angle black, and a suboblique black mark resting in a sinuation of the upper edge, as well as an oblique suffused grey spot on the costa beyond the middle. There is a transverse dark grey pre-tornal blotch reaching two-thirds across the wing, the anterior edge irregular, the posterior formed by a straight dark fuscous line extended almost to the costa. There are four black marginal dots around the apex. The hindwings are light grey, the apex and upper part of the termen narrowly whitish.
