The Cetti's Warbler was originally described as Sylvia cetti, honouring Francesco Cetti.
Later it was moved into its own genus. However, the genus name is slightly different, ending in -ia, so it is Cettia cetti and not Cetti cetti.
Something similar happened with Bulwer's Petrel: originally described as Procellaria bulwerii, it was then moved into genus Bulweria. In this case, an "a" was added but an "i" was dropped.
There must be some sort of rule behind these spelling changes. Can someone please shed some light on this?
