Again, "homo" refers to humans, which orcs aren't. Just keep thinking "No homo!", but in a Latinate way.
How about a nod back to old-school "piggish" depictions of Orcs, and call them Phacochoerus (the genus name for warthogs) sapiens?
Or if you want them to be a member of the goblin species, Cobalus (goblin) Phacochoerus, making them the "warthog-like goblins".
