Apatetris elaeagnella is a moth of the Gelechiidae family. It was described by Sakamaki in 2000. It is found in Japan (Honshu and Kyushu). The wingspan is 5.4-9.2 mm. The forewings are cupreous black, but shining cupreous violet between the plica and dorsum and silver on the basal one-seventh. There are three costal silver strigulae running in parallel with each other on the median one-third. Three similar strigulae are found in the basal half of the dorsum and a silver blotch occupies the apical one-eights of the forewing. There are also two white blotches, one at the apical one-fourth of the costa and the other at the apical two-fifths of the dorsum. The hindwings are fuscous. There are two generations per year.
