Adult ( Fig. 30 ). Wingspan 11.0−16.0 mm.

Male genitalia ( Fig. 44 ). As illustrated.

Female genitalia ( Fig. 55 ). Papillae anales quadrate, with dense setae. Anterior apophyses about 1/3 length of posterior apophyses. Eighth tergite with posterior margin semicircularly convex at middle; eighth sternite with anterior margin subquadrately protruding medially, lateral band extremely narrow, reaching near anterior margin. Ostium bursae large, nearly trapezoidal, sclerotized along margins, with weakly sclerotized C-shaped plate along posterior and lateral margins. Ductus bursae membraneous, longer than corpus bursae, slender in basal half, coiled and widened in distal half. Ductus seminalis arising from where ductus bursae starting coiling. Corpus bursae ovate; signum transversely elliptical, placed at posterior 2/5, with transverse carina.

Diagnosis. This species resembles E. epichthonia ( Meyrick, 1935) in appearance, and the differences between them are stated under the latter species. The male genitalia of E. marginans resemble those of E. heppneri ( Park, 1995) . Encolapta marginans can be separated by the valva without a process on the ventral margin; whereas the valva has an angular process on the ventral margin in E. heppneri .

Distribution. China (Beijing, Hebei, Henan, Shaanxi, Shanxi, Tianjin).

Remarks. The female of this species is described for the first time.
