Diagnosis. Forewing length 8.5–10.0 mm ( Fig. 8 ). Hypatopa binotella is similar to H. tianshanica Sinev, 1993 in the male genitalia; both have an apically bifurcate phallus. Hypatopa binotella can be separated from the latter by the gnathos notched medially on the posterior margin, and the phallus with numerous fine spines at apex ( Figs. 16, 16a ). In H. tianshanica the gnathos is not notched on the posterior margin, and the phallus lakcs fine spines at the apex. Hypatopa binotella is also similar to H. biprojecta in the female genitalia, but it can be separated by the possession of a process arising from the posterior margin of the signum ( Fig. 23 ); in H. biprojecta the process is from the middle of the signum.

Distribution. China (Heilongjiang), Northern Korea, Russian Far East, Siberia, Europe.

Note. This species is recorded for the first time in China.
