With respect to latin naming, the following rules do apply to day.
If the name of the genus is male, the name of the species and the name of the subspecies get "us" as an ending; e.g. Agapornis canus, Agapornis canus ablectaneus, Agapornis personatus, Agapornis pullarius. If the generic name is female, e.g. the genus Cacatua (Cockatoos), than species and subspecies get "a" as an ending, e.g. Cacatua galerita. For many years people have written cana, pullaria and personata, probably as a result of a mis spelling later on adopted by others.
Dr. Karl Russ (1901) did use the right names at that time and wrote the names of the Agapornis species with "us" as an ending. These days in modern European bird literature the right names are used with regard to the genus Agapornis.

The I.C.Z.N. (International Committee for Zoological Nomenclature) in London keeps record of the scientific names. Agapornis is a male word, therefore the adjectives of this family name such as personata, cana etc. must be written according to the Latin grammar with the male ending "us" instead of "a" (=female) since 1900-1995. This is common practice in German languages.

An exception is taranta: that is a geographical name.

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.

During my involvement in setting up a research network, it came to my notice that a sex-linked mutant called Texas clearbody was developed in the USA. If I am well informed this mutation already appeared in the late fifties and nowadays is known as pallid. We now have prove that this gene is an allele of the sex-linked ino locus.
My conclusion is based on the fact that cocks of the genotype inopd/ino, both alleles recessive to ino+, are clearbodies. Therefore the symbol inopd for sex-linked clearbody is proposed.
