Diagnosis. Adult ( Fig. 9 View FIGURES 7–10 ) with wingspan 21.0̅23.0 mm. This species is characterized by the forewing has a small, blackish brown costal spot on inner margin of antemedial line, and a large, subtriangular, blackish brown posterior patch on outer margin of lower half of antemedial line; the uncus is gradually narrowed, the gnathos is clubbed, dentate apically, the transtilla has right-angled triangle postero-lateral lobe in the male genitalia ( Fig. 20 View FIGURES 19–20 ); the antrum is semicircular, the signum situates at posterior 2/5 of the corpus bursae in the female genitalia ( Fig. 31 View FIGURES 25–31 ). It is related to D. dichromella , but differs as noted in the diagnosis of the latter.

Material examined. 97 male and 77 female specimens in different localities of China are examined .

Distribution. China (Anhui, Beijing, Guangdong, Gansu, Guizhou, Henan, Hubei, Shandong, Shaanxi, Sichuan, Tianjin, Yunnan, Zhejiang), Japan.

Remarks. Three species Trachycera nipponella , T. yakushimensis and T. vicinella described by Yamanaka (2000) from Japan are synonymized with this species, because the differences among them are too tiny to be interspecific: the uncus is broader or narrower apically, the postero-lateral lobe is shorter or not, the valva is a little narrower or not. We treated these as intraspecific differences. Among these species, T. nipponella has the greatest diffrences with D. paradichromella , as is noted in the original description: nipponella ‘…apical process of gnathos nearly crescent-shaped, not stick-like as in paradichromella , and apex pointed, slightly hooked, apico-dorsal portion minutely indented…’. These differences, however, might be caused by mounting slides: crescent, slightly hooked at apex when mounted laterally; clubbed, minutely indented at apex when mounted dorsal-ventrally.
