Pionea puralis South, 1901: 493.

Diagnosis.

Forewing length: 11.0-14.0 mm. Ecpyrrhorrhoe puralis is almost indistinguishable from E. longispinalis and E. biaculeiformis in appearance, but can be distinguished in the male genitalia (Fig. 33 ) by the small and excurved sella, much larger juxta with distal 2/3 bifid, anellus with comb-shaped spines (attached to distal phallus end of in Fig. 33 ), and in the female genitalia (Fig. 48 ) by the antrum with two rounded sclerotized processes, and basal 2/3 of ductus bursae bearing a slim sclerite.

Remarks.

Ecpyrrhorrhoe puralis is mainly reported from central and southern China and Japan. Solis et al. (2010) considered it was introduced in eastern North America and spread following the invasive host Paulownia tomentosa (Thunb.) Steud.
