Antaeotricha substricta is a species of moth of the family Depressariidae. It is found in French Guiana.[1]
The wingspan is about 15 mm. The forewings are white, slightly tinged grey, especially towards the dorsum and with dark fuscous markings. There is a very oblique streak from the base of the costa, becoming longitudinal and reaching one-fifth. There is also a mark on the base of the dorsum and an irregular suffused streak from one-fifth of the costa to the dorsum beyond the middle, sharply dentate-angulated outwards in the middle (with the angle indicating the first discal stigma), and with a smaller dentation below the middle, enlarged into a spot on the dorsum. There is some fuscous suffusion towards the dorsum beyond this and an irregular line from the middle of the costa to a subtriangular spot on the tornus, the second discal stigma forming a dot attached to its posterior edge. A straight cloudy line runs from the costa at three-fourths to the middle of the termen, on the costa forming a wedge-shaped dilation and there are six cloudy blackish terminal dots. The hindwings are whitish-grey, with the costa somewhat expanded on the anterior half, a pale whitish-ochreous subcostal hair-pencil extending from the base to two-thirds, the costa beyond this whitish suffused.[2]
