Stenoma sericata is a moth of the Depressariidae family. It is found in Brazil (Amazonas) and French Guiana. The wingspan is about 23 mm. The forewings are whitish-fuscous, with a faint violet tinge and with the costal edge orange. The stigmata are small and dark fuscous, the plical obliquely beyond the first discal. There is a small dark fuscous spot on the middle of the costa, and a larger triangular one at four-fifths, where a curved series of dark fuscous dots runs to the dorsum before the tornus. There is also a terminal series of subquadrate dark fuscous dots. The hindwings are whitish-yellowish, suffused with ochreous-yellow towards the apex and upper part of the termen.
