Approach (MUGZY/N90) brought two aircraft onto the ILS for Runway 19 at TEB.  Aircraft X (Phenom 300) was number 1 and Aircraft Y (G-V) was number 2.  At the time of their transfer to my position (local control) the aircraft were less than 3 miles apart (2.5; estimated) and Aircraft Y at the time did not have Aircraft X in sight when asked.  Aircraft X was cleared to land; and I considered sending Aircraft Y around as there was loss of separation before I could apply tower visual.  Before I could call approach for instructions on how to take Aircraft Y off the approach; Aircraft Y reported Aircraft X in sight and I cleared Aircraft Y to land.  At this time I had both aircraft in sight from the tower and deemed there was sufficient distance between them to allow safe landing.  Both aircraft landed without incident.  Approach needs to better sequence arriving aircraft; especially with the new wake turbulence recategorization that TEB and N90 are participating in.
A Local Controller at TEB reports a loss of separation given to him at Local; he then tries to use visual separation but cannot. Finally sees both aircraft and lets the second aircraft land instead of sending it around.
