A newly identified species as of August 2024, the Frejuke fall right in the middle of well-known to obscure as far as new species from "The Rise of Skywalker" go!
Andraven
One of the more basic sentient pachydermoid species to appear in the franchise, who still have at least some distinct lore, as well as a unique cultural aesthetic.
Celegian
One of the more unique sentient species of the Star Wars universe, these floating, poison-breathing, telepathic jellyfish-brain-beings were confirmed to technically be Canon thanks to illustrator Mark Brooks still being on Twitter/X.
Barundi
A species who were indoctrinated and broken up by the cultish "Thelvin Order" to protect their various religious sites and objects including a precious and ancient Sith gemstone/key.
Krex
Like the Daichyura, the Krex are one of the final sentient species to be introduced within the EU, added to Star Wars: The Old Republic around a year after the current Canon was already underway!
Dybrinthe
The Dybrinthe are Star Wars' answer to "Mortal Engines," a people whose home moon is covered in massive mobile cities who scour the planet's surface for gas to convert into valuable fuels!
Mournish
No, that's not a Nautolan, but instead one of a few "Nautolan-passing" species found throughout the universe (who we know very little about).
Fiumarian
A species with a reputation for being able to use their intellect to divorce their perspective from any sort of opinions, capable of taking truly neutral stances on debates if they so desire, but usually only do so if it can earn them wealth or influence.
Villarandi
A rather standard insectoid species who we've seen very few of, yet they've already made quite a few appearances throughout The High Republic.
Abinyshi
Taking to the stars around the same time as the Duros and Corellian Humans some time in the galaxy's distant past, the Abinyshi were much less influential than their spacefaring peers, remaining relatively secluded until the Empire's rise to power.
