Ecpyrrhorrhoe biaculeiformis Zhang, Li & Wang, 2004: 317.

Diagnosis.

Forewing length: 12.0-16.0 mm. Ecpyrrhorrhoe biaculeiformis is similar to E. puralis in habitus, but can be distinguished by the much larger size and much paler coloration (Fig. 21 ), in the male genitalia (Fig. 37 ) by the width of valva relatively even or slowly widening distally, a sella with the basal part bearing 4 spines on the apex and with a distal process, the narrow and short juxta with distal half bifid, the anellus with two separate spines (attached to distal end of phallus in Fig. 37 ); in the female genitalia (Fig. 52 ) by the antrum bearing a pair of nearly triangular and wrinkled sclerites at posterior margin, and the short sclerite of ductus bursae ~ 2/5 of its length.
