RE: https://mastodon.green/@plazi_species/115865079842879526
It is a complex #scientific #study in which C. J. Glasby et al. (2025) deal with the #Marphysa #mossambica #speciesgroup (#Polychaeta: #Eunicidae). Species complexes always indicate very closely related and #similar #species and #taxonomic uncertainty about where species boundaries have been crossed and where they have not. The authors redescribed the species Marphysa mossambica and described two #newspecies.

This subject comes up fairly often, so I'm putting my mini-essay here as an easy reference. Feel free to share, or copy and paste with attribution, as you see fit. Comments, suggestions, and corrections are welcome. 🦖 🧪 🚀 ✍️

Michael Crichton's main reference when writing #JurassicPark was Gregory Paul's Predatory #Dinosaurs of the World. That's how we ended up with human size "velociraptors," later retconned to the considerably larger #Utahraptor. Although the poor creatures still have broken wrists and a severe case of mange.
Paul is a notorious #lumper, who likes shoving distantly related organisms into the same #taxonomic category. (The opposite of lumpers are #splitters, who try to put every specimen into as distinct a category as possible.) But even he never claimed they were the same species. Rather, he put them into the same genus, making #Deinonychus into another species of #Velociraptor, i.e. V. antirrhopus instead of D. antirrhopus.
This isn't entirely a crazy idea. Lots of modern genera have species with similar body plans but enormous size differences. Consider #Panthera, the big cats, which contains species from P. uncia, the #snowleopard, to P. tigris, the #tiger—even though tigers are generally about five times the mass of snow leopards, similar to the ratio between D. antirrhopus and V. mongoliensis.
However, there are enough other differences between Deinonychus and Velociraptor that even Paul has long since admitted this was a mistake. No #paleontologist now doubts they each belong in their own genus. Unfortunately, since Jurassic Park has so thoroughly cemented the idea of the big V, I doubt it will ever go away.

An updated checklist of geometrid #moths (~14% of all moths) was published last year as the Online #Taxonomic Facility of #Geometridae
https://geometroidea.smns-bw.org/introduction
The data are now also in #ChecklistBank and will replace the current outdated #LepIndex list in #CatalogueOfLife, @gbif, etc.
I've also edited #Notodontidae in the @TaxonWorks Global Lepidoptera Index dataset at least to match Schintlmeister's 2013 catalogue (now handling later works):

The mountains are calling!🏔️
In a new study of high-altitude adaptation in #alpine #plants, Zhang et al. give us a better view of high-#taxonomic convergent evolution underlying #genetic #adaptation to complex #environments.

Finished putting the #mammal boxes in the #zooarch collection into modern #taxonomic order today! I do still need to do one final pass-through to filter in some stragglers and new specimens, but then it's on to #birds!

An updated #taxonomic checklist of the Portugese #oaks is online, including good photos and SEM images of #trichomes, recognition of a few new #hybrids, and an updated key to the country's oaks.
This should also be a helpful resource for the #nomenclature of the #Mediterranean white oaks and holly oaks.
