There is no mention of either DNA or genitalia in The Code. The Code only covers nomenclature, not taxonomy.

But the Code specifies what elements must be met in order to describe a species right? So for example, you have to specify the etymology of the name, the type location, and the description of the proposed new taxon must also meet some minimal standards. Sure, you don’t have to describe the genitalia or DNA, but my point is that it’s 2024…shouldn’t there be a description of those things? DNA is an integral part of pretty much any study these days revising a species or genus or whatever.bobw wrote: Mon Oct 21, 2024 11:38 am There is no mention of either DNA or genitalia in The Code.

There is absolutely no requirement in the Code to specify the etymology of a new name, and in fact the word 'etymology' does not occur anywhere in the Code.eurytides wrote: Tue Oct 22, 2024 5:22 am But the Code specifies what elements must be met in order to describe a species right?

I agree that most modern papers include DNA analysis as at least part of the justification for conclusions found in the work, but there is no reason why this should be mandated in the Code. DNA can certainly be a good indicator for which morphological characters are important in a classification and which are not, but even in DNA analysis there can be very different results depending on which and how many genes are included. Trees based on COI only can look very different to those based on a large number of genes or the whole genome. Interestingly, in some groups COI tree topology is really well resolved and is the same as that for whole genome analysis, but in others COI analysis produces completely unresolved trees with specimens from each population mixed up across the whole tree.eurytides wrote: Tue Oct 22, 2024 5:22 am DNA is an integral part of pretty much any study these days revising a species or genus or whatever.
Oh I agree, but Adam was right in saying it wasn’t an absolute requirement.

First, it really caught me off guard that Adam, of all people, being so taxonomy-minded would hold such a liberal perspective; I thought Adam would be more strict and "by the book."
Beyond that though, doesn't it open the door to commercial dealers naming forms as species?
It doesn't actually matter whether the stated characters really do differentiate the taxon ... that is for a subsequent taxonomist to decide, and is an important distinction between the purpose of the ICZN Code to govern nomenclature only, not taxonomy.13.1. Requirements. To be available, every new name published after 1930 must satisfy the provisions of Article 11 and must

Really? But all I've read for decades is big fights over what's not a valid subspecies (which predates genetics) and synonymization. I'm so confused.adamcotton wrote: Fri Oct 25, 2024 8:30 pm With regard to Papilio bjorkae and other 'glaucus' putative taxa, it is good to put a name to those that can be defined morphologically and then see what genomics uncovers.
Adam.
It would certainly not be a good idea to describe a specimen known to be a hybrid, especially if artificially produced ... these latter are excluded from the ICZN Code under article 1.3.3.
The names of species such as Papilio appalachiensis which are of hybrid origin, but not actually direct offspring of two different species are covered by article 17.2.Article 17. Names found to denote more than one taxon, or taxa of hybrid origin, or
based on parts or stages of animals or on unusual specimens. The availability of a name is not
affected even if
17.1. it is found that the original description or name-bearing type specimen(s) relates to more than one taxon, or to parts of animals belonging to more than one taxon; or
17.2. it is applied to a taxon known, or later found, to be of hybrid origin (see also Article 23.8); or
17.3. it is based on only part of an animal, or one sex, or one stage in the life cycle, or one of several dissimilar generations, or one morph or caste of a polymorphic species, or a parthenogenetic form, or a specimen which is an unusual example of the taxon (for exclusions see Articles 1.3 and 45.6).

The ideas behind the Code were developed over a period of many years from the mid 19th Century to the mid 20th Century, with important principles proposed in 1930, culminating in the first edition of the ICZN Code published in 1961. Subsequent editions (currently the 4th) updated rules in such a way that changes did not apply retroactively. Thus there are clauses 'before 1930', 'after 1960', etc.Chuck wrote: Mon Oct 28, 2024 5:47 pm I've oft wondered, if given only the written description if I'd be able to draw and color the taxon. Probably not. I also have noted that is generally where the errors are- swapped references to images, wrong side of butterfly, etc....right through all peer review.
I'd rather have an image with arrows pointing to the various aspects, or however marked, as done on MST by Wang and Schmidt. And side-by-side images contrasting to related taxa.
Not knowing how old the code is, I wonder why (somewhat obvious) the "in words" requirement. Is there a requirement for color images?
It is also worth mentioning that the criteria for publication are not as tight as Chuck may think. As long as the publication does not contravene articles 8 and 9 (in particular, plus others), and if it is electronic only (not produced on paper) it complies with ALL requirements in the 2012 amendment then the publication is considered valid under the Code.Recommendation 13A. Intent to differentiate. When describing a new nominal taxon, an author should make clear his or her purpose to differentiate the taxon by including with it a diagnosis, that is to say, a summary of the characters that differentiate the new nominal taxon from related or similar taxa.
There are (even today) cases where one person is author, editor, reviewer and publisher of his own journal in order to publish his own papers without 'interference'. I don't want to be more specific (naming names), but I assume this happens across Zoology, not just in Lepidoptera. Taxonomists just have to deal with issues in all nomenclatural works that are validly published.Article 8. What constitutes published work. A work is to be regarded as published for the purposes of zoological nomenclature if it complies with the requirements of this Article and is not excluded by the provisions of Article 9.
8.1. Criteria to be met. A work must satisfy the following criteria:
8.1.1. it must be issued for the purpose of providing a public and permanent scientific record,
8.1.2. it must be obtainable, when first issued, free of charge or by purchase, and
8.1.3. it must have been produced in an edition containing simultaneously obtainable copies by a method that assures numerous identical and durable copies.
