letcher (1979) stated:-
A. mixtalis is a junior subjective synonym of Cylomia mopsaria Guenée, 1857, in Boisduval & Guenée, Hist. nat. Insectes (Spec. gén. Lépid.) 10: 124.
Audia Walker is not preoccupied by * Audia Zetterstedt, 1849, Diptera Scand. 8: 2920 (included by Neave, 1939, Nomencl. zool. 1: 356). The latter is an incorrect subsequent spelling of Acidia Robineau-Desvoidy, 1830 / Diptera. Audia Walker was originally proposed in the Pyralidae, but has since been transferred to the Geometridae; I have not found any published reference to the transfer.
See also Cyclomia Guenée, 1857.
Fletcher & Nye (1984) stated:-
Audia was established in the Pyralidae, and was transferred to the Geometridae by Fletcher, 1979, in Nye Generic Names Moths World 3: 23.
Parsons et al. (1999) included AUDIA Walker, 1863 [April 18[; and CERASYMPIASTA Möschler, 1890 as junior synonyms of CYCLOMIA Guenée, 1858.
