The Grubbyl's body is much shorter and way thicker than that of the Speedbiter. They might be able to share a genus, but it's unlikely.

The Speedsucker has one proboscis as it's main mouth and it's head seems to be merged with its body. The Pathola has insectoid pincers as it's main mouth, and a better-defined head. As well as many poisonous parts. Not only would they not share genus, but I'm willing to put them in separate families as well (Carnitoria for Pathola, and Proboscitoria for Speedsucker)

Lastly, the Leechman has six limbs, and the Avisnailer-Furian has four. There are many more differences, such as localization of the proboscides and presence of a long tail in the latter, but just that is enough to set them apart.
