Antaeotricha trichonota is a species of moth of the family Depressariidae. It is found in Brazil (Rio Grande do Sul) and Paraguay."Antaeotricha Zeller, 1854" at Markku Savela's Lepidoptera and Some Other Life Forms
The wingspan is 21–24 mm. The forewings are ochreous-whitish with a fuscous dot above the fold near the base and a short greyish-ochreous transverse streak from the costa beyond this. There is a transverse fuscous blotch from the costa at one-fifth reaching to the fold, suffused blackish on the lower edge and on the upper part of the anterior edge. The dorsal area to the fold is pale pinkish-ochreous, including a blackish dot at one-third, a transverse ferruginous shade beneath the middle of the wing, and limited by a fuscous dot on the fold preceding this, a ferruginous mark before the extremity, and a small triangular dark ferruginous spot at the apex. From above the dorsal edge from near the base to this spot a fringe of projecting whitish-ochreous hairscales is found, curved downwards. There is also a blackish dot beneath the costa beyond the middle, where a very oblique pale ochreous shade to the middle is continued by a curved series of dark grey dots to a small dark grey spot on the tornus. There is a pale ochreous curved shade near before the apex and termen. The hindwings are ochreous-whitish, beneath the dorsal fringe of the forewings a fringe of upwards-curved whitish-ochreous hairscales meeting it. The apical edge is whitish, preceded by a greyish tinge and the costal area is expanded on the basal two-thirds, with a projecting fringe of dense greyish-ochreous hairscales, and a long expansible ochreous-whitish subcostal hair-pencil from the base to beyond the middle.Exotic Microlepidoptera 3 (5-7): 235
