40-43C... Miltonia... Odondtoglossum... Zygo.... But your nights cool down. I think that is it.
I've been told Nepenthes absolutely require constant high humidity to pitcher. The ones I see in people's collections here don't pitcher, and don't look so good, even though they're in greenhouses.
Sounds like you need some Cyrtopodium, Eulophia and Oeceoclades.
