I fell down a big 'standards of identity' rabbit hole recently😅

As a note, American cheese doesn't necessarily require that name. If it's just cheese with emulsifiers, acidifiers, etc. it is just American cheese; if it's 51% cheese but also contains dairy like milk, whey, or cream, it's a "cheese food". The use of milk protein concentrate makes it a "product".

My favorite binomial is Dendrocygna autumnalis, for the meaning and mostly for the way it feels to say.

It's (in my opinion) very robustly ctenos. There's been a few sponge-sister papers recently, but there were some pretty severe flaws. The gene linkage paper by Schultz et al. (2023) on the issue was very strong evidence for ctenos.

In which name?

. . .The position here taken seems so obviously unwarranted as to hardly merit discussion." Similarly, "Under No. 41: No one accepts the idea that the type of the genus is the sum of the species."

"We must dissent, however, from Rule 38 in so far as it relates to 'co-types,' this part being to the effect that when a species is 'described from more than one specimen, no single one being selected as the type, the 'type' in this case is the 'sum of the co-types'. . .

I'm interested in this too. All I can say is that it predates 1878, as Strickland's Rules for Zoological Nomenclature refers to types. The Merton Rules in 1896 had some whacky concepts about them, excoriated by Coues and Allen in 1897. . .

Dean Koontz is Fred Willard in a 2009 Bieber wig. I knew it all along.

...we raise some points that are more broadly relevant. These regard study design, model implementation & testing, and interpretation, in particular relating to taxon and site downsampling, model fit, & sensitivity tests. We also clarify the common conflation of compositional and site heterogeneity.

In the Zoological code, the relevant articles are 27, which forbids marks like hyphens except when Art. 32.5.2.4.3 applies: "If the first element is a Latin letter used to denote descriptively a character of the taxon, it must be retained and connected to the remainder of the name by a hyphen."

Here is a confocal stack of a clonal raider ant antenna from first author and FISHerman extraordinaire Giacomo Glotzer. You can see the densely packed cell bodies of olfactory sensory neurons, along with fluorescent signal from two different odorant receptors and an intergenic region.
