Diagnosis. Z. hepariella is characterised by the forewing with a dark purple streak costal line from base to near apex. Zelleria hepariella is similar to Z. japonicella , but can be separated by the absence of small dark purple spot at dorsal margin of forewing before middle, the narrower elongate-ovate valva, relation of length of valva to its maximal width 2.33 in the male genitalia, and the antrum which is about 1.5 times as long as the diameter of ostium bursae in the female genitalia.

Redescription. Adult (Fig. 1). Wingspan 11–12 mm. Vertex with rough and erect cream white scales extended to dorsal half of frons, frons otherwise with cream white appressed scales, scales around compound eyes brown. Antenna filiform; scape pale yellow brown with brown pecten; flagellum cream white, ringed with dark brown. Labial palpus porrect, blunt-tipped, ochreous inside, dark brown outside, with ochreous tip. Thorax light brown mixed with violet luster; tegula dark purple. Legs light brown mixed with violet luster, faintly irrorate with white scales; hind tibia and tarsus pale gray, with a faintly paler ring at base of each tarsal segment. Abdomen pale shining gray. Forewing elongate, narrowed distally, ground color yellow brown with violet, lustrous crescent patch at basal area, anothr along costa to apex, violet, lustrous scales suffused from about distal 2/3 to termen, fringe ochreous gray. Hindwing and fringe ochreous gray.

Male genitalia ( Figs. 7a, 7b ). Socius narrow, with a thorn at apex, curved outwardly. Tuba analis membranous. Uncus convex. Valva elongate-ovate, with a small ridge before 1/4 of dorsal margin; relation of length of valva to its maximal width 2.33. Sacculus with short stiff setae. Gnathos elongate, with drop-shaped median plate. Saccus narrow, slightly shorter than 1/3 length of valva. Aedeagus about 1.25 times as long as valva, cornuti composed of 2 rows of small spines.

Female genitalia ( Fig. 10 ). Papilla analis semiovate. Apophysis posterioris 0.8 times as long as apophysis anterioris. Apophysis anterioris branched. Lamella postvaginalis setose, with posterior rounded lobes. Antrum narrowed funnel-shaped, sclerotized, about 1.5 times as long as diameter of ostium bursae. Ductus bursae over 2.5 times as long as corpus bursae, tubular, membranous, granulose in proximal half beyond ductus seminalis. Corpus bursae long, narrow, gradually dilated anteriorly. Signum absent.
