Narrative:

I was training an advanced trainee on the final position. We were getting busy and our feeder controllers were giving a somewhat aggressive feed including leaving aircraft on a new arrival. When this happened; my trainee started to try and sort out some problems with the feed he was getting; forgot to turn aircraft Y to final off the base leg. I did not realize that aircraft Y didn't get the turn to final; resulting in a loss of separation between him and aircraft X on the straight in to a parallel runway. I would recommend people think before leaving aircraft on this new arrival during busy sessions.

Title: TRACON Controller providing training failed to note that the trainee did not issue a turn on vector; resulting in a conflict with parallel traffic; a new arrival procedure was cited as contributing to the error.
