In some aspects, they are as different as Patho and Sucker. Of course, there is also the integument, the presence of fur, the hoove type, etc. But their two main morphological differences (at least in my opinion) are the body structure and mouth type. And the same things happens between Patho and Sucker: the former has three different mouths (two proboscides and an insectoid mouth), and the segments/head-neck-body of its trunk can be easily differentiated; the latter, however, has only one mouth (a proboscis), and its body is much more uniform, making it hard to distinguish the allegedly-existent sections of the trunk. If we add up Patho having six bulb-like parts Sucker lacks, Sucker having two rear cillia Patho lacks, and the "stems" on Patho's eyes, we have two very different cells that should be separated by genus at least.

And before you come up with the same arguments again: coloration and texture are, again, irrelevant, as well as pupil size; and merely having mouths, a body or "non-head parts" are insufficent, as these traits are different in each cell despite falling into a same category.
