Key to Archiearis species of the Baikal region

1. Male antenna bipectinate ( Fig. 3A ); fringe of both wings unchequered; forewing with weak light costal spots or without them, hindwing with small discal spot. In male genitalia ( Figs. 32C, 32D ) valva comparatively broad and short, narrowing medially; uncus strongly broadened medially; aedeagus with narrowed coecum. In female genitalia ( Fig. 32I ) signum comparatively short, lanceolate; ovipositor long, apophyses posteriores almost twice as long as apophyses anteriores................................................................................................... A. notha (Hübner, 1803)

- Male antenna filiform ( Fig. 3B ); fringe of both wings chequered (at least partially); forewing usually with whitish costal spots, hindwing with large discal spot. In male genitalia ( Figs. 32A, 32B ) valva very long and slender, gradually narrowing distally; uncus not broadened medially, with almost parallel lateral margins; aedeagus with wide rounded coecum. In female genitalia ( Fig. 32H ) signum elongated, tongue-shaped; ovipositor very short, apophyses anteriores and apophyses posteriores rather short and stout...............................................................
