Stenoma patens is a moth in the Depressariidae family. It was described by Meyrick in 1913. It is found in Peru. The wingspan is 34-43 mm. The forewings are glossy light greyish-ochreous with the costal edge whitish. The stigmata are small and dark fuscous, the plical very obliquely beyond the first discal. There are very faint traces of a curved darker transverse series of cloudy dots at two-thirds and a curved series of subcrescentic dark fuscous dots from three-fourths of the costa to the dorsum before the tornus, sinuate inwards towards the costa. There is also a terminal row of blackish dots. The hindwings are light fuscous, on the apical third obscurely suffused with whitish-ochreous.
