Tabernillaia is a genus of moth in the family Gelechiidae.

It contains the species Tabernillaia ephialtes, which is found in Panama.

The forewings are dark bronzy fuscous, with a slight coppery tinge about the middle of the wing in a strong light.

An outwardly oblique, ovate, snow-white patch descends from the costa, at about one-sixth, slightly overreaching the fold.

Another, rounded, rather smaller white spot lies on the costa at about one-fourth from the apex.
