Compsolechia abruptella 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, the forewings with a black basal point and a black spot in the disc near the base and a white line extending obliquely outward from two-thirds of the length of the costa, and forming a very acute angle, contiguous on the inner side with two longitudinal black streaks. The space between this line and the exterior border has a slaty tinge, and contains some minute white streaks and one minute black streak, which seems to be a continuation of the hinder end of the black streaks. There is also a broad black streak along the apical part of the costa and the marginal line is cinereous. The hindwings are cupreous-brown.
