Hapalochilus nitidus (?)

I got this labeled H.nitidus. The flower is a bit under 3" wide. The plant appears much different from other plants (pseudobulbs and leaves) that I have know as nitidus and the flower is much smaller and proportionally a bit different. Does anyone have any thoughts on whether this is a widely variable species or a number of species that are frequently confused/lumped/misidentified? I really like this group and would like to propagate it, but not make a hybrid. Unfortunately, I only bought one plant of it at the time.

 

For comparison, here is an image of another plant I have from a different source.

 

Thanks, Jon. If someone here doesn't have an idea I'll reach out to some of those you mentioned.

 

I tried to self it and broke the column getting the pollen in the stigma. I'll be waiting for another bud.

 

I have a division of this plant http://orchidspecies.com/orphotdir/hapformosus.jpg but haven't bloomed it yet. My (vague) sense of formosanum is that the lip is proportionally longer than it is on my unknown. Thanks for suggesting this.
