Aeschynanthus sp. in Crocker Range

I had a self-service trip in the state of Sabah, Malaysia at the end of August, this place is famous for its various endemic flora and fauna. Although the territory of Sabah keeps under exploitation so far, visitors still can find the interesting nature in some reserved areas.

I found this Aeschynanthus sp. on my way back to Kota Kinabalu, the capital city of Sabah while the van went through the Crocker Range. This plant is totally out of my knowledge of Aeschynanthus species, so I don't know the ID. I can only see it's a bit different from the current known Aeschynanthus species, as for the name ... it will be very appreciated if any one may know the answer. :-)
