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.
