Diagnosis.

Forewing length: 11.0-14.0 mm. In appearance, Ecpyrrhorrhoe rubellalis resembles E. minnehaha , but can still be recognized by its larger forewing length, yellowish brown ground color of wings with yellow fringe, and more oblique antemedial line of forewing (Fig. 18 ); in the male genitalia (Fig. 34 ) by the broader valva with truncate tip, and the nearly spine-shaped, thin and short sella, by the phallus apically with a densely dentated, triangular projection and a thick spine bearing a broad and long, spinulose base on the anellus; in the female genitalia (Fig. 49 ) by the antrum without spinules and large second (posterior) signum.
