[Taxacom] Objective synonyms?

The ICZN Code hasn't really defined these terms. Perhaps the ICBN Code has done better? The main confusion here comes about from the fact that species names are binomial: you need to somehow think of synonymy at the species level detached from generic considerations. It makes NO SENSE to say that Aus bus and Cus bus are objective synonyms because they are homotypic, unless Aus and Cus are objective synonyms ...

I had been led to understand that "objective synonym" was the same as a
botanical "nomenclatural synonym"; nomenclatural synonyms are by
definition homotypic. As I learned synonymy, the homotypic /Encelia
nutans/ Eastwood and /Enceliopsis nutans/ (Eastwood) A. Nelson are
synonyms, and I find nothing in the ICBN to contradict that. Perhaps the
issue is that in botanical nomenclature such names do not have the same
authorship, because the codes deal with authorship in a subtly different
Most of what I know of zoological nomenclature I got from Ed Wiley's
/Phylogenetics/, and it could be both out-of-date and incorrect.
