Epicephala spinula is a moth of the family Gracillariidae, one of the most primitive groups of ditrysian "micromoths". Within its family, it belongs to the subfamily Gracillariinae. Even though it was first scientifically studied in 1929, for many decades the specimens of this moth were mistaken for the related Australian species E. colymbetella, and their distinctness was only realized in 1986. It is found on the Marquesas Islands, where it occurs at least on Nuku Hiva, Ua Pou, and Fatu Hiva, and though little-known it is apparently not uncommon. The holotype specimen, a female, is USNM 100839.
