For the sake of clarity and to avoid confusion, I would like to propose to abandon the use of the name "lacewing" in species other than the Budgerigar [Melopsittacus undulatus].
There is more than overwhelming evidence that lacewings are the result of crossing-over between the sex-linked cinnamon and ino loci. Thus, they are actual cinnamon-inos and do not represent a separate locus or allele as several authors have postulated in the past. Therefore the use of the term "cinnamon-ino" is much more appropriate and hereby proposed for all psittacine species involved except for Budgerigars.
