[Taxacom] Fwd: Authority with date (zoo) / without date (bot)

[Tony Rees]

Yes, this is normal. Another difference is that in zoology, when a species
has changed genus, the name of the author who first moved it is not given,
whereas in botany, they are: in your example (Martius) Solms in botany, the
equivalent in zoology would just be (Martius, 18xx) or whatever the
original publication date would be.
