Key to Chlorissa species of the Baikal region

1. In male genitalia ( Figs. 35F, 35G, 35J , 36K, 36L ) aedeagus dorsally with broad semicircular lobe in medial part near anterior opening ( Figs. 36G, 36H ); vinculum rather angled: in lateral view anterior parts of its arms and axe of saccus form angle <90° ( Figs. 27E, 27F ).
