Antaeotricha frontalis is a moth in the Depressariidae family. It was described by Zeller in 1855. It is found in Mexico and Guatemala. The structure of vein 8 of hindwings in the male is extraordinary. It is appressed to the cell towards the base, then curved up towards the costa, and presently receives towards its apex what appears to be an additional vein rising from the cell at about two-thirds, but must really be a long very oblique bar formed by extension of an original anastomosis at a point.
