Apatetris halimilignella is a moth of the Gelechiidae family. It was described by Walsingham in 1904. It is found in Algeria. The wingspan is 8-9 mm. The forewings are cream-white, barred with fawn-ochreous, of which there is a spot at the base of the costa, a straight transverse fascia at one-third, a broader one at the middle, and a still broader band covering the apex and termen. On the bands is a slight dusting of black scales along the costa, and a group of the same forms an elongate spot on the outer half of the central fascia about its middle. The hindwings are shining, iridescent rosy grey.
