Stenoma epicnesta is a moth of the family Depressariidae. It is found in Guyana.[1]
The wingspan is 14–15 mm. The forewings are whitish ochreous tinged and sprinkled with fuscous and with the base white on the upper half, produced between a short streak of fuscous irroration on the fold, and a fine fuscous dash above this. There is a short very oblique irregular fuscous streak from the costa at one-fourth. The plical and first discal stigmata are suffused and fuscous, the second discal well marked and dark fuscous, surrounded with whitish. There is a suffused fuscous spot on the costa in the middle, where a very undefined shade passes behind the cell to the dorsum at three-fourths, preceded by some whitish suffusion towards the costa. A suffused triangular fuscous spot is found on the costa at three-fourths, where a strongly curved cloudy fuscous line runs very near the termen to the tornus, the terminal area beyond this is suffused with whitish and there is a marginal series of blackish dots around the posterior part of the costa and termen. The hindwings are light grey in males and grey in females.[2]
