Tags for species can be labelled as characters if the species is specific to a series.
That's not the reasoning why species tags are sometimes rendered as character tags, concentrating on humanoid non-enemy/general species (so, Deku Scrub over Goomba/Mareep). The main reason why it happens is because they exist in place of proper character tags, because said tags don't exist.
Looking at Zapdos' example of Warhammer, you have Orks, but you also have T'au. For the former, you generally don't get individualized art, they're rendered generic, effectively. Combine that with a lesser presence online, and the fact that they have a gentag makes sense. For the latter, you have a lot more individualized 'waifu'/OC art, and they have a larger presence online in part because of the waifuing. But you can't give each T'au OC its own chartag because most times they aren't given a name and are just supposed to be general T'au, so the species tag gets turned into a chartag.
To quote from a past discussion (forum #186303):
If we need a rule, I'd say that if it's an animal species with a consistent unique appearance, like a Pokemon, or an RPG monster, or a mascot creature, then it gets a chartag. If it's a humanoid race, then it gets more difficult. Draph is a gentag because there are a lot of named Draphs, and it would be weird to give them two chartags. On the other hand, Miqo'te is a chartag because most Miqo'te posts are unnamed OCs, and it feels a little weird to have posts with an identifiable character but no chartag. I don't know if there's a good answer here. It might be easiest just to say that all humanoid races are gentags.
It's this same principle that led many MMO race/species tags to be chartags, like the aforementioned Miqo'te, because clearly the OC needs to be tagged with something. The only thing that can be done to make them gentags is to provide an alternative - in the MMO race/species tags' case, that required the creation of a new tag (topic #19866). With both past discussions and what Zapdos said in mind, because many Zelda races have named (and thus taggable) individuals in them, the prospect of making their species tags chartags is needless. To quote the same discussion too:
For me it comes down to what makes the tag list easiest to read.
Do you suddenly want every named Zora character to add an extra tag to the chartag section of a post? And you can't add a clause saying named characters don't count to species tags - we've tried that with youkai tags and Touhou before, it does not fucking work.
