Compsolechia monochromella is a moth of the Gelechiidae family. It was described by Walker in 1864. It is found in Brazil (Amazonas) and Peru. Adults are cinereous-brown, more cinereous and tinged with aeneous beneath and the forewings with very indistinct darker speckles and three indistinct blackish marks in a line near the costa. The space towards the exterior border is rather paler and the marginal points are blackish and very minute. The hindwings have a cupreous tinge, a little darker than the forewings.
