Elves and Paravians it is, Dek (not knowledgeable enough about the others, especially those from TV, to form a reasonable opinion).
How about this one: Tolkien's elves, specifically his Eldar and most specifically his Noldor, almost always receive identities. Whether one is discussing the strongest personality (e.g., Fëanor) or a rather quiet one (Celebrián), if they have a role in the story, they receive names at least, and usually personality descriptions where they do not have "first person" participation.
Wurts, by contrast, will occasionally name the centaurs (e.g., Shehane Althain), but otherwise, when a Paravian appears, they are almost of one mind and body, and it wouldn't matter whether one Riathan (again, for example) replaced another, or a different Sunchild had administered to the removal of the curse from Arithon; their actions and responses would largely be the same, regardless of which member of their race was involved. A curious thing, too is the importance that knowledge of a true name has inside Wurts' creation, and the fact that the sunchildren and unicorns almost never (I would say never, but it's hard to remember that exactly when the story spans more than a decade in the workings) have names, at least not such as are revealed to us....
