Anacampsis cornifer is a moth of the Gelechiidae family. It was described by Walsingham in 1897. It is found in the West Indies (St. Croix and St. Thomas). The wingspan is 10-11 mm. The forewings are greyish ochreous, indistinctly speckled with fuscous, a black dot at the extreme base of the costa, two fuscous dots in the fold, two on the discal cell, a slight fuscous costal shade above the end of the cell, followed by a pale ochreous spot, a few fuscous scales lying around the apex and termen. There is a slight greyish suffusion across the middle of the wing, and beyond it from the pale costal spot a curved band, paler than the ground-colour, is indistinctly traceable across the wing. The hindwings are brownish grey.
