You are right the ruler shows millimeters and centimeters, sorry for the missed info.
I dont think it's a genus related to Pleurothallis or Platystele...It's not cespitose, but rhizomatous and leaves aren't fleshy
Growth habit looks like a Scaphyglottis (Hexsea) but the flower doesn't.

As far as I know Scaphyglootis new growth starts from the center of the previous vegetation, this doesn't.
Habit is more similar to Bulbophyllum (rhizome) and Restrepia (sheath on rhizome up to the leaves)...it's a real mistery....
