Stenoma fallax is a moth in the family Depressariidae. It was described by Arthur Gardiner Butler in 1877. It is found in the Amazon region of Brazil.[1]
The wingspan is about 22 mm. The forewings are pale shining greyish brown with an abbreviated oblique darker line from the base of the costa, and a second line (not abbreviated), crossing the centre of the cell, angulated upon the median vein, where it runs very obliquely to near the external angle. The discocellulars, and a subapical costal spot are dark brown and the external area is rather paler than the rest of the wing. There is a series of marginal blackish dots. The hindwings are testaceous (reddish yellow).[2]
