I’m not talking about intergrades (subspecies #1 x subspecies #2 breeding), I’m talking about different subspecies, but parents can be identified to subspecies. I am going to create, since there are numerous iNat observations that remain unidentified, the Gibraltar Buzzard which is a “self-sustantin…

I don’t think they exist, taxonomically speaking. The definition of a hybrid, at least according to the ICN, is the offspring of two separate species.

I don’t necessarily agree because that statement implies that subspecies don’t exist. Yes, a hybrid is the offspring of two separate species, but those species can have subspecies and that means if a species with subspecies hybridizes, then the hybrid has a subspecies parent. Here’s a good example: …

I’m not saying that infraspecies cannot form crosses, only that taxonomically they are not a hybrid.

I’ve seen and used myself the hybrid taxon Trachemys gaigeae x T. scripta elegans. The former (Big Bend Slider) is currently considered monotypic and the hybrid events involve one subspecies of the Pond Slider which has been introduced widely outside of its range. To our knowledge only that subspec…

[image] mftasp: The definition of a hybrid, at least according to the ICN, is the offspring of two separate species. Do you mean nomenclaturally defined according to ICN? The code doesn’t directly deal with taxonomic opinion or taxonomic definitions. I can’t find the entry in ICN that defin…

Some of the ICNafp rules apply only to hybrid taxa of particular ranks, or address what rank should be assigned to hybrid taxa, but the ICNafp is otherwise agnostic on the topic. E.g., from H.3.1: “Hybrids between representatives of two or more taxa may receive a name.” There is no limitation that o…

For algae, fungi, and plants governed by the ICNafp, assuming that there is no published name for either one, we would refer to the two hybrids you mention by different hybrid formulae: Buteo buteo subsp. buteo × Buteo rufinus subsp. cirtensis Buteo buteo × Buteo rufinus subsp. rufinus Under the …

I take that back. The ICZN’s search bar just doesn’t work. “1.3 Excluded from the provisions of the Code are names proposed […] 1.3.3. for hybrid specimens as such (for taxa which are of hybrid origin see [Article 17.2]” So, the ICZN is explicitly agnostic. If it really is a taxon of hybrid orig…

Like your namesake, genus Aspidoscelis — many hybrid lineages have an actual binomial if they are perpetuating populations. The occasional weird individual of hybrid origin that is apparently not being perpetuated is described by the hybrid formula Aspidoscelis something x A. something_else.

I was thinking animalologists used hybrid formulae, too. However, my experience with the nomenclature of hybrid animals is pretty much limited to Aspidoscelis, and it’s not a topic I’ve been much engaged with over the past decade or so. Odd that the ICZN doesn’t mention hybrid formulae, though, at l…
