The wingspan is 7.2–8.8 mm. The forewings are brown with a narrow white band on the dorsum from the base to 2/3 of the entire length and with two pairs of narrow white bands beginning at the costal and dorsal margin near 1/2 to 3/4 length of the wing and extending obliquely toward the wing apex, terminating before reaching mid-width of the wing. The dorso-distal band is accompanied by another parallel band of same size on the distal position and there is a narrow silver band with metallic reflection extending from the costa to the dorsum at 5/6 length. The distal 1/6 is orange-brown with a black dot centrally, franked by short white band near the dorsum. The distal end is fringed with a narrow white band. The hindwings are brown.

The larvae feed on the seeds of Glochidion obovatum and Glochidion rubrum.

Etymology

The species name is inherited from Tegeticula corruptrix, a derived parasitic species of yucca moth. Epicephala corruptrix has a potential to corrupt the mutualistic relationship with its host because the species induces gall formation in pollinated flowers which then hardly produce seeds.[1]
