Key to separate the genera Perissana and Raunolina

1 Metope with median carina not reaching its upper margin ( GNEZDILOV & WILSON 2006: Fig. 1b ). Fore wings with many transverse veins (reticulate venation) (GNEZDILOV & WILSON 2006: Fig. 1a ); CuP distinct in proximal half of the wing. Gonoplacs rounded, with dorso-caudal angles in lateral view not protruding above apex of anal tube ( GNEZDILOV & WILSON 2006: Fig. 5 ). ................................................................ Perissana Metcalf, 1952

– Metope with median carina reaching its upper margin ( Fig. 7 ). Fore wings only with longitudinal veins ( Figs 1–4 , 8 ); CuP indistinct. Gonoplacs triangular, with dorso-caudal angles in lateral view clearly protruding above apex of anal tube ( Figs 10, 12 ). ............... ............................................................. Raunolina Gnezdilov & Wilson, 2006 , stat. nov.
