You have the valve. Rockledges pic shows it; you can see the TPS which is common to the shaft on the butterfly valve. The other pic shows one very nicely too. It's nothing more than a round disk in a cylindrical section that rotates via a shaft; such shaft has a linkage to tie it into the accelerator pedal. Lawnmowers, weed wackers, blowers, snow blowers, edgers, etc that have a carb or some form of EFI need a way to regulate airflow; the butterfly valve does it. Engines with a carb often us one for the choke. If you can regulate your engine speed, you have it; it would be about impossible to drive any vehicle w/o it. One exception is a carb with a slider, but even at that it's purpose is the same as the butterfly valve.

What you took a pic of is the MAF:Mass Airflow Sensor. You need to follow that tube that says "caution" on the top of it where it meets up with the engine, thats your TB. Take off that hose clamp, and look inside, you will find your Butterfly plate there. If you still cant find it, let me know, and i'll take some pics of my truck since we have the exact same setup.
On edit, i realized I had a pic of my engine compartment. I have an aftermarket intake on, so its not going to be exactly the same. Between the air cleaner and the shiney metal tube is the MAF circled in red. This is whats connected to your black box where your air cleaner is, and what you took a picture of. What i circled in green is the Throttle body. You need to unhook your black tube that says caution on the top of it, mine is chrome, yours is black, unhook that, and look inside, you will see your butterfly valve.
