The term “correct original spelling” has a special meaning which is different from what is commonly understood by correct spelling. Names are assumed to be spelled correctly in the work where they were established except if they are incorrect because of one of the reasons given in article 32.5, e.g.:
- if there is evidence in the work of a spelling or printer’s error, e.g. a species was said to have been named after Linnaeus, but the name is spelled ninnaei, when it should have been linnaei, it is to be corrected;
- if the name is published with an accent, apostrophe, numbers, spaces, abbreviations, or other symbol than the 26 letter Latin alphabet, then these are to be corrected;
- hyphens are similar but are retained where the first letter is describes a character of the species for example in the butterfly name Polygonia c-album refers to a white c-shaped mark on the wing.
However incorrect Latinisation is not to be corrected (Article 32.5.1).
Incorrect endings may also need to be corrected (Article 34) e.g.:
- If the ending of a species name which is an adjective does not agree with the gender of the genus then it has to be corrected.
- However names based on personal names with incorrectly Latinized endings are not corrected as this would cause instability (Article 32.5.1, glossary definition of Latinization). I.e. a species which was named smithi after a woman with the surname smith is not incorrectly spelled even though the normal feminine Latinization is smithae.
