Can a basement floor drain be tapped into to run the drain from a nearby newly installed basement toilet into it?

If you just plan on putting the toilet on top of the floor drain the answer is no. The floor drain if it leads to a septic system or city sewer would have a trap in the line which will not work with a toilet. Depending on the size of the pipe 3" minimum you could cut the floor and tie a toilet into the line. It would also have to be properly vented. I would consult a plumber on the job. Its also possible that the floor drain just goes to a dry well which could not be used. Even if it could not be used there are other ways to install a toilet below the septic or sewer line.

Yes. Toilet, shower, sink, or any other fixture that you might have needs to have a vent. Why? --->>> Toilet, shower or sinks are all independent fixtures where they all individually need air in order to flow properly. Any of these fixtures will not take air from the same vent you have at the basin.
