Epicephala tertiaria is a moth of the family Gracillariidae first described by Hou-Hun Li in 2015.

The wings are brown to dark brown, the forewings with three pairs of white striae from both the costal and dorsal 1⁄4, 2⁄3 and 3⁄4 extending obliquely outward to the middle and end of the cell as well as outside of the cell respectively.

The dorsum has a broad white band along the basal 1⁄3, a narrow silvery-white fascia bearing a bluish metallic reflection from the costal 5⁄6 to the dorsum, arched outward medially.

The distal 1⁄6 is ochreous, with a central black dot near the fascia at 5⁄6, with a broad white band along the costa and dorsum.
