Antaeotricha basalis is a species of moth of the family Depressariidae. It is found in Argentina."Antaeotricha Zeller, 1854" at Markku Savela's Lepidoptera and Some Other Life Forms
The wingspan is about 27 mm. The forewings are ochreous-whitish with three short blackish bars suffused together with grey forming an elongate blotch along the basal fourth of the costa and with projecting ochreous-whitish dorsal scales. There is a fine linear fuscous dot on the fold at one-third of the wing and a blackish-fuscous dot at the end of the cell, as well as a faint pale fuscous irregular curved shade from beyond the middle of the costa to three-fourths of the dorsum and a faint light fuscous rather curved shade terminating in the tornus, not nearly reaching the costa. A fuscous elongate mark is found on the costa at three-fourths and there are two or three small cloudy fuscous spots around the apex. The hindwings are whitish-grey, becoming whitish anteriorly. The costa is expanded from the base to two-thirds, with a broad projection of long rough hairscales suffused with dark grey beneath, and a long whitish subcostal hairpencil from the base lying beneath the forewings.Description of Antaeotricha harpobathra in Exotic Microlepidoptera 1 (16): 499
