Stenoma stabilis is a moth of the Depressariidae family. It is found in French Guiana, Guyana and Brazil (Amazonas). The wingspan is 25-27 mm. The forewings are light brownish with the extreme costal edge whitish-ochreous and with a small dark purple-fuscous spot on the costa before one-fourth, giving rise to a short oblique zigzag fuscous line. The plical and second discal stigmata are small, dark fuscous and obscure. There is a large triangular dark purple-fuscous spot on the middle of the costa, and a smaller one at three-fourths, where a curved series of sometimes indistinct dark fuscous dots runs to the dorsum before the tornus. There is also a marginal series of dark fuscous dots around the apex and termen. The hindwings are grey-whitish, somewhat greyer posteriorly.
