Notes. The taxon moesta has been treated by some authors (Hacker 1990; Ronkay et al. 2001) as a Siberian subspecies of M. adusta. Examination of the genitalia of the lectotype of Hadena adusta var. moesta (Fig. 112) showed that it is conspecific with M. bathensis. The taxon moesta is a monotonous brownish grey form of M. bathensis occuring in East Palaearctic. The taxon urupino was treated by Ronkay et al. (2001) as a subspecies of M. bathensis, but Kononenko (2005) treated it as a junior synonym of bathensis. By the examination of the material from Kurile Islands and Kamchatka, it was found that the reddish form described by Bryk (1942) as urupino (Figs 37, 38) occurs together with darker form common in Europe (Fig. 35) and the monotonous brownish grey form described as moesta (Fig. 36). Thus, Pacific populations of M. bathensis cannot be treated as a distinct subspecies.

Diagnosis. Wingspan 35–49 mm. The external differences of M. bathensis are described in diagnoses of M. adusta and M. kobyakovi. The male genitalia (Figs 75, 76, 92) differ from M. adusta in the somewhat narrower juxta with shorter serrated parts of its apical processes (in M. bathensis distal third, but in M. adusta distal half serrate), larger elongated cucullus with longer corona, more curved digitus, apically obtuse carina, shorter eversible dorso-lateral bar beginning from apex of carina and having longer teeth basally; and from M. kobyakovi in the somewhat narrower juxta with shorter serrated parts of its apical processes (in M. bathensis distal third, but in M. kobyakovi distal half serrate), larger elongated cucullus with longer corona, more curved digitus, shorter eversible dorso-lateral bar of carina with longer teeth basally. The female genitalia (Figs 112, 113) differ from M. adusta in the narrower ostium bursae with a concave posterior margin, narrower ductus bursae and smaller signum; and from M. kobyakovi in the narrower ostium bursae with a concave posterior margin, and somewhat narrower corpus bursae.

Distribution. Eurasiatic Palaearctic. North Europe, NE European part of Russia, Ural, South Siberia, Transbaikalia, Mongolia, Russian Far East (including Kamchatka and Kurile islands), Northeastern China (Manchuria), Korea, Japan.
