Taxacom: Clarification RE e-publication (zoology) - new name has ZooBank LSID (or doesn't), publication does not

[Tony Rees]

Dear all,

Just checking that my understanding of the requirements for e-publication
as per the current ICZN Code is correct...

- The Code requires the work in which a new taxon name is proposed to have
an associated (and valid) ZooBank LSID stated in the publication itself,
but LSIDs for new taxa are optional (although desirable)

- Conversely, new names in a work in which a new taxon has an associated
visible ZooBank LSID, but the work itself does not, are not effectively
published until the print version appears?

As an example of the latter, I have before me the new genus
name Yanjisuchus, published by Rummy, Wu, Clark, Zhao, Jin, Shibata, Jin &
Xu in the journal Cretaceous Research, 129, Jan 2022: 1-23. The new genus
does not have a ZooBank LSID stated, although its sole included
species, Yanjisuchus longshanensis, does: urn:lsid:zoobank.org:act:
C0F36066-D6AD-4FA7-A8C9-1DA81D424459 (currently "held but not publicly
visible" in ZooBank). The journal volume that includes the paper is dated
2022, but the work appeared online in 2021 (2 September), however does not
appear to have any registered ZooBank LSID (unless I have missed it of
course).

>From the above I conclude that both the genus (with no ZooBank
registration) and the species (with ZooBank registration) must be
considered as published in 2022 for nomenclatural purposes, not 2021; if,
however, the work itself bore a ZooBank LSID then both the new genus and
the new species would bear the publication date 2021, even though only one
of the new taxa (the species but not the new genus) was registered in
ZooBank at the time...

Just seeking some confirmation from others more expert than myself in this
area that this conclusion is correct!
