Physeta vs Herpetotheres (1 Viewer)

Sorry for this useless thread but I can't find the original falconid topic

I need some clarification please

In his analyse, Vieillot (1816) introduced the name Physeta with Falco sufflator Gmelin as type species. The next year, here he created the genus Herpetotheres for Falco cachinnans Lath. (by monotypy) along with this note: ''Ce genre remplace celui qui est sous le nom de Physète dans l'analyse de mon Ornithologie élémentaire'' (I don't how to translate this sentence). However, he doesn't give the reasons for this change. As both names were assigned to the same bird, can you explain why the name Herpetotheres is used instead of Physeta, which has priority, at least, in theory. Should Physeta not be the true applied name ?, unless it's a nomen oblitum.

Thanks

Perhaps he thought Physeta was too similar to Physeter (Sperm Whale) to be valid as a separate name?

Highly possible, at this time it was a common habit. But I need more explanation.

Linnaeus 1758 (who is the actual author of the species name):

sufflator. 16. F. cera pedibusque luteis, corpore fusco albido, occulorum operculis osseis.
Habitat Surinami. Rolander.
Corpus supra fuscum plumis basi albis; subtus luteo albo fuscoque maculatum, uti etiam rectrices. Nares lobo carneo intercalari. Iratus aut territus caput inflat ad magnitudinem corporis.

This translates more or less as:
I think this is generally regarded as a nomen dubium nowadays.

Nice. This explains why Physeta is rejected.

I knew that it was an useless thread.
