Please, calm down. And no, it can't. Genera are much more specific than classes, and while they admit general criteria like those (well, not the smooth purple skin, but the fact that their head is well defined), they need to be more specific, and share many more features, often to the point they look like slightly modified clones of each other. The Speedsucker has cillia, while the Pathola doesn't have them. The Speedsucker lacks the bulb-like structures across the Pathola's body. The Pathola has antennae-like eyes, while the Speedsucker has round more ordinary eyes. The Pathola's head is separated from the body by a neck, while that of the Sucker is basically merged with the body. And most importantly, the Pathola has three mouths (two proboscides and an insectoid jaw), while the Speedsucker only has one. The differences are enough to classify them in different genera.
