(Figs. 2, 8a, 8b, 11)
Zelleria japonicella Moriuti, 1977: 221; Sohn et al., 2010: 2810; Yamauchi & Hirowatari, 2013: 161. TL: Japan, Hokkaido.
Diagnosis. Z. japonicella is characterized by the dark purple spots suffused before middle of dorsum. This species is externally similar to Z. hepariella Stainton, but can be distinguished by the ovate valva, its maximal width 1.89 times as in the male genitalia, and the antrum about 2 times as long as the diameter of ostium bursae in the female genitalia.
Redescription. Adult (Fig. 2). Wingspan 12–13 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 light brown. Antenna filiform; scape pale yellow brown with brown pecten; flagellum cream white, ringed with dark brown. Labial palpus porrect, blunt-tipped, ochreous inside, light brown outside, with ochreous tip. Thorax yellow brown mixed with violet luster; tegula dark purple. Fore- and midlegs from femur to tibia dark brown, mixed with ochreous, tarsus pale ochreous, ringed with dark brown; hindleg from femur to tibia dark brown, mixed with ochreous, tarsus ochreous. Abdomen pale shining gray. Forewing elongate, narrowed distally, ground color brown, with violet, lustrous, crescent-shaped patch at basal area, black brown streak from base to apex, mixed with violet luster along costa, distal 2/3 of wing length suffused with black brown scales; pale ochreous dorsal streak from basal 1/6 to 2/6, dark purple spots at middle of dorsum; fringe formed of black brown and purple, lustrous scales on termen, ochreous gray on basal 1/3 to termen. Hindwing and fringe ochreous gray.
Male genitalia (Figs. 8a, 8b). Socius narrow, with a thorn at apex and curved outwardly. Tuba analis membranous. Uncus convex. Valva ovate, relation of length of valva to its maximal width 1.89; with a small ridge before about 1/4 of dorsal margin; sacculus with short stiff setae. Gnathos elongate, with drop-shaped median plate. Saccus narrow, about 1/3 length of valva. Aedeagus about 1.4 times as long as valva, cornuti composed of 2 rows of short spines.
Female genitalia (Fig. 11). Papilla analis semiovate. Apophysis posterioris as long as apophysis anterioris.
Apophysis anterioris branched. Lamella postvaginalis setose, with posterior rounded lobes. Antrum cylindrical, sclerotized, about 2 times as long as the diameter of ostium bursae. Ductus bursae over 2 times as long as corpus bursae, tubular, membranous, granulose in proximal half beyond ductus seminalis. Corpus bursae long, narrow, gradually dilated anteriorly. Signum absent.
