I think the consensus is most likely that it is N. sibuyanensis x talengensis.
Guess the only way to figure it out is to mate a batch of N. sibuyanensis x hamata and a N. sibuyanensis x talengensis and compare results. But due to variabilty who knows if you could come up with a definative answer even then. Probably could, I would imagine.
It's a beauty no matter what it is.
The peristome curves inward in a way I wouldn't expect from either parent; perhaps it contains hints of N. talangensis? It seems that some people speculate that the cross is actually N. sibuyanensis x 'Lady Pauline'...
"I, for one, can't wait to grow Nepenthes extincta!"
I was about to bring up Nepenthes 'Lady Pauline', as well. I had just been to a CP nursery with a couple large N. 'Lady Pauline's, and I see some similarity. It is clearly not her, but certainly may have some Pauline genes in there somewhere. Whatever it is, it's pretty!
~Edit~ Here's a picture. Definitely not the same, but similar?

Reason: Added picture, and fixed poor grammar
If you shake a rain stick, you get rain. I need a hamata stick.
Well, I am going by memory and this huge battle on the trop nep forum from way back.
Both male parents mentioned here were brought up.
Rob maintained at the time that the pollination was done carefully, and that females and males are housed in different greenhouses. Regardless of that, Rob said Lady Pauline had not flowered to even be in the mix , IIRC.
You can definitely see the sib in this.
This example is the best I have seen, but I have not seen one in a while. I wish it was mine, lol.
Thanks for the replies everyone.
Interesteing observations. They definitely point me in the general right direction to its parents.
I wonder if Rob has any larger specimens to compare??
