Need help on identificating this

This is a Bulbophyllum I got from a friend almost 4 years ago. What I know about Bulbophyllum's is that they need absurdly moist medium to grow - they are common in the most humid areas of the forests around here -, so I thought it wouldn´t survive long in my porch... but it did. It started growing like crazy and now launched 2 inflorescences. One of them already faded away.

I took a picture of it when the first flowers opened. I want to know which species of Bulbophyllum this is. The flowers are really small, I couldn´t find a position to take a detailed picture. Does anyone have a hint?

Picture #1: This is the plant. The inflorescences are those flat, leaf like structures with a row of flowers in the middle (I´m holding the lower one, so you can compare the size of the flowers by the size of my finger).

#2: Close up of the inflorescence. The lower flower is already open. All the flowers get aligned in the same position, facing upwards.

#3: I tried to get a close up of the flower, but the size of it, the position and the light didn´t help me. The dorsal sepal is yellow and straight. The lateral sepals are broad, fused, with the tips folded backwards; they are yellow outside and dark red inside. The petals are linear, yellow. And the labellum is pendulous, yellow to green on the base and dark red on the top.

The closest I could find was B. falcatum var. falcatum although I can't vouch for the name being correct http://www.ggcg.st/images/orchid.htm

I´m not sure, the pseudobulbs of that one are angulate. My plant has semi-conical pseudobulbs. The bloom is pretty close, though. Thanks for your attention, Baa.

I have never seen anything like that before in my life!
