Antaeotricha plerotis is a species of moth in the family Depressariidae. It was described by Edward Meyrick in 1925. It is found in Peru.[1]
The wingspan is about 17 mm. The forewings are shining white with the costal edge pale ochreous and with an oblique dark fuscous spot from the costa at one-fourth, and a small roundish spot in the disc beyond it. A small linear somewhat oblique dark fuscous mark is found on the upper angle of the cell, and a dot on the lower somewhat beyond it. There is an oblique wedge-shaped dark fuscous spot from the costa at two-thirds with some fuscous suffusion beneath it, and a trapezoidal dark fuscous spot suffused anteriorly on the dorsum before the tornus, these representing a fascia broadly interrupted in the middle. Some fuscous irroration is found before the termen, and six dark fuscous pre-marginal dots leave the terminal edge and interspaces clear white. The hindwings are whitish suffused light greyish-ochreous on the posterior third, greyer towards the apex, the extreme apex white and the costa dilated on the anterior half, with a broad projection of white and dark grey scales before the middle, as well as a whitish-ochreous subcostal hairpencil from the base reaching to two-thirds, lying beneath the forewings.[2]
