From the pinkish paint on it I think its part of one of the lost motion springs (part of the ivtec system). Referencing your first photo, two of these springs can be seen, they are hidden in the large metal casting (Lost motion holder) that fits over the valve train, you can see the one on the left is either less compressed (or perhaps missing that broken bit) than the one on the right.
Any codes at all?
Sorry I wish it was less serious, perhaps its just left over damage from a prior failure and the mechanic didn't fish out the spring fragment.

No codes. The engine is running smooth. Except that, sometimes on idle i feel vibrations in the cabin, more then normal.
Unfortunately the valve cover is already in place and i can't check the lost motion header for missing parts. I have two more photos, but they are not very clear.
RedCoupe, most probably this little spring as you suspect is lost motion spring. It's interesting that it is very tiny. Maybe it is only a broken part of one of the lm springs... :facepalm:
How it looks like:

It's not uncommon these springs to break. Here is one recall for Fit model

Certainly looks like part of the spring including the little metal seat built into the end. Definitely a bummer.
update
I replaced the broken LMA spring, but didn't find the cause for breaking.
1. Defective spring. The other three springs are ok;
2. Rocker arm issue. It will break again. I will update this thread.
3. Mistake in assembling process. The spring is not positioned correctly when LMA and the holder were installed.
