Diagnosis.

Forewing length: 9.0-14.0 mm. In appearance, Ecpyrrhorrhoe digitaliformis is indistinguishable from E. celatalis (Walker, 1859), but it can be distinguished from it in the male genitalia (Fig. 31 ) by the tapering and curved valva, the thumb-shaped, excurved and setose sella inflated distally, by the stout, sclerotized, finger-shaped dorsal protrusion of the sacculus, by the anellus with a string of minute spines and a cone-shaped group of large spines (attached to distal phallus in Fig. 31 ), the modified distal ends of the arms of the juxta, and the shape of cornuti; in the female genitalia (Fig. 46 ), by the antrum with a vertical wrinkled area in the middle.

This species is closely related to E. brevis based on molecular data, and similar in appearance and male genitalia, but can be differentiated by the slender and excurved sella, the thick protrusion of sacculus, and the slender arms of juxta bearing a tooth-shaped process, as well as the characters mentioned above.
