Mystery nep

I am in Taiwan right now and I visited the local open air flower market. They sell from carnivours to waterlilies. I found a stall with a few neps and i bought one. It has long narrow leaves and light green pitchers with a slight "waist" , a green alata-like peristome and a light reddish green band around the peristome. Do any of you have any clue what it is?

Any chance of a picture? It sounds like N. Gracilis, but that is only my uneducated guess!

Sounds like a young ventricosa

Sorry I don't have a picture and the tendrils are thicker than a ventricosa and the pitchers are slightly fuzzy.
