Cotton, A.M., Bolotov, I. N., Gofarov, M. Y., Gorbach, V. V., Kolosova, Y. S., Zheludkova, A. A., Kondakov, A. V. & Spitsyn, V. M. (2021). The correct name for the South Western European species recently separated from Parnassius mnemosyne (Linnaeus, 1758) (Lepidoptera: Papilionidae). Ecologica Montenegrina, 43: 56–58.
The name nebrodensis Turati is shown to be unavailable and the first available name for the species is chosen by invoking the First Reviser Principle under the ICZN Code as Parnassius turatii Fruhstorfer, 1908. Rothschild was determined to be the first author to confer availability on the name nebrodensis by application of the Code.
Please also see the previous paper, which I noticed used an unavailable name for a new species:
Bolotov et al. (2021) Parnassius nebrodensis: A threatened but neglected Apollo butterfly species from Southern Europe (Lepidoptera: Papilionidae). Ecologica Montenegrina, 40: 140–163.

Bolotov et al. only declared Parnassius nebrodensis to be the oldest name for a species separated from the wide ranging Parnassius mnemosyne this March, based on DNA analysis of the species by Fabien Condamine.
As soon as I saw the paper I realised that they had chosen an unavailable name (described as an aberration), contacted the authors and they asked me to write a correction for them. The whole mess became much more complicated because the next oldest available name for the species was actually a series of several names all published on the same day. I applied First Reviser Principle under the Code to choose one name to have priority over all the others, and thus Parnassius turatii becomes the correct name for the species.
Surprisingly nebrodensis has always been used as the subspecies name for the population from Sicily despite it being an unavailable name, and I have determined that Rothschild (1918) was the first author to confer availability on the name.
