Stenoma trirecta is a moth in the Depressariidae family. It was described by Meyrick in 1931. It is found in Brazil. The wingspan is about 31 mm. The forewings are whitish-fuscous speckled dark fuscous, the veins indicated by faint darker lines. There are three nearly straight dark brown transverse lines, the first about one-third, rather oblique, obsolete at the extremities, the second beyond the middle, nearly parallel, the third from four-fifths of the costa to just before the tornus, slightly excurved on the lower half. There is a dark brown terminal line. The hindwings are grey.
