There is a good chance it is some sort of N. trusmadiensis. It is a little unusual for N. lowii to not show some hairs under the lid at a decent size like that. My main reason for suggesting not ruling it out yet is because the pitcher didnt' look properly developed particularly in the lid.
I have seen a few lowii (from Wistuba and BE) that have been this size and no/minimal hairs. Heck I was growing a BE clone that only 1 in 5 pitchers ever made hairs. It was always a picture worthy event for me when it did make hairs LOL.
Pyro do you know if he has ever released some seed grown plants? Like if he had extra in the lab and just potted them up instead of keeping dozens of different clones? I know Malesiana did that in the past when they would initially release a new item.
Best I know he did not. I believe the situation was as described earlier where a batch of TC propagated macrophylla material was turning out "odd" looking as people were growing them out.
