(Figs. 3, 12a, 12b)
Zelleria silvicolella Moriuti, 1977: 222; Yamauchi & Hirowatari, 2013: 162. TL: Japan, Honshu.
Diagnosis. Z. silvicolella is characterized by the forewing having a white streak or spot along costa from basal 1/3 almost to apex. The female genitalia are otherwise similar to those of Z. asiatica sp. nov., but can be separated by the following characters: ductus bursae less than 2.5 times as long as the corpus bursae, the signum band-shaped with denticles, extending about half the length of the corpus bursae in Z. silvicolella.
Redescription. Adult (Fig. 3). Wingspan 12–13 mm. Vertex with rough and erect cream white scales extended to dorsal half of frons, frons otherwise with pale ochreous, appressed scales, scales around compound eyes pale brown. Antenna filiform; scape pale gray with brown pecten; flagellum cream white, ringed with dark brown. Labial palpus porrect, blunt-tipped; ochreous inside, orange yellow outside, with ochreous tip. Thorax yellow brown, mixed with violet luster; tegula yellow brown with violet luster. Fore-, and midlegs light brown with violet luster, faintly irrorated with white scales; hindleg dark gray mixed with white scales, each segment of tarsus dark brown, irrorated with white scales. Abdomen pale shining gray. Forewing elongate, narrowed distally, ground color light brown; violet, lustrous patch at basal area, black brown costal streak extended from basal patch to basal 1/4; violet, lustrous scales at basal 1/3, white streak almost from basal 1/3 almost to apex, irrorated with dark brown scales, white spot at apex, distal area suffused with violet luster, white and dark brown scales scattered in median area; fringe ochreous gray. Hindwing and fringe ochreous gray.
Female genitalia (Figs. 12a, 12b). Papilla analis arrow-shaped. Apophysis posterioris 0.9 times as long as apophysis anterioris. Apophysis anterioris branched. Lamella postvaginalis setose, with posterior wide rounded lobes. Antrum cylindrical, sclerotized. Ductus bursae over 2 times as long as corpus bursae, tubular, membranous, granulose in proximal half beyond ductus seminalis. Corpus bursae ovate; signum band-shaped, 1/2 length of corpus bursae with denticles.
Material examined. [OPU] 1 ♀, (Holotype), Japan, Honshu, Iwateken, Gando, 22. VI.1965 (T Oku).
Distribution. Japan (Hokkaido, Honshu).
Host plant. Oleaceae: Syringa reticulata Blume (Moriuti 1977).
Remarks. The species is reported from the Russian Far East by Gershenson (1986), but illustrated specimens are certainly not conspecific with Z. silvicolella Moriuti, having differences in the length of antrum and the shape of the signum in the female genitalia. This record, followed by (Sinev 2008; Ponomarenko 2016) is thus erroneous.
