3.3. Publication date of the first description

Scoble & Pitkin (2024) come to the conclusion that volume 9 of the "Species général des lépidoptères", i.e. volume "I" of "Uranides et Phalénites" was published between 2 and 8 January 1858, volume 10 of the "Species général des lépidoptères", i.e. volume "II" of "Uranides et Phalénites" between 13 and 19 March 1858. The printed year "1857" should therefore be corrected to "1858" for both volumes - as already stated by earlier authors and also handled accordingly in Lepiforum. As Scoble & Pitkin (2024) strongly recommend, in such cases the correct year of publication is also placed in square brackets in Lepiforum, here "[1858]" for both volumes. We are therefore deliberately deviating from the "Recommendation 22A.2.2" of the 4th version of the ICZN (1999), which no longer mentions these square brackets (unlike in the previous versions) and even more so from the completely confusing "Recommendation 22A.2 .3", which would like to place the printed date - if absolutely desired - after the unbracketed publication date in round or square brackets [here "Guenée, 1858", "Guenée, 1858 (1857)" "Guenée, 1858 ("1857")" "Guenée, 1858 [1857]" or "Guenée, 1858 ["1857"]"]. Like Scoble & Pitkin (2024) - and the vast majority of entomologists - we continue to adhere to the rule of the earlier versions of the ICZN, according to which a publication date derived directly from the paper is written without brackets, whereas a publication date derived indirectly from other sources is placed in square brackets.
