Antaeotricha isosticta is a moth in the Depressariidae family. It was described by Edward Meyrick in 1932. It is found in Mexico.
The wingspan is about 27 mm. The forewings are whitish-ochreous, with the dorsal three-fifths faintly greyish-tinged and the extreme costal edge whitish. The stigmata are dark grey, the plical small, obscure and rather obliquely beyond the fiĀrst discal. There are two or three greyish dots in an oblique series from a small spot of greyish suffusion on the costa just before the middle to the second discal and there is a very oblique hardly excurved series of six grey dots from beneath the costa at two-thirds to near the termen in the middle, then angulated and continued as a faint dotted greyish line to the tornus. A marginal series of dark grey dots is found around the apex and termen. The hindwings are whitish-grey.
