Notes . (1) The type species of Chamyla ( Figs 9–12 , 24, 25 , 29 ) and Grumia ( Figs 15–17 , 27 , 32 ) display no significant morphological differences from the typical Isochlora ( Figs 1, 2 , 20, 21 , 30 ) and therefore cannot be considered as subgenera of the latter. For this reason, we follow the wide concept of the genus suggested by Lafontaine (1998) and consider Grumia and Chamyla as junior synonyms of Isochlora . (2) The genus was characterised in detail by Lafontaine (1998) .
