Cosmia praeacuta. Generic combinations from Lafontaine and Troubridge (2003).

Chytonix parvimacula. This name was inadvertently omitted from the Franclemont and Todd (1983) check list. Examination of the holotype reveals that the name is a synonym of Cosmia praeacuta (= Cosmia parvimacula (Smith, 1903), comb. n., syn. n.).
