IT's hookerianum. The only three species in that group that has 'two eyes' is pulchellum, gibbsonii and hookerianum. D. gibbsonii flower is a little smaller and the lip is more rounded and they bloom more like pulchellum and fimbriatum.
It's very beautiful and hard to find. You are very lucky to find it. =) Send me the keikies when you have it!! lol
