Which Pleurothallis species is this?

[camille1585]

Akerne Orchids (a well known nursery in Belgium) recently asked for help on Facebook to identify a Pleuro species which they have lost the records for.

Does anyone know what it could be?

Original message:

Identification request.
Can somebody help to find the correct name for the following Pleurothallis species?
Our records contain absolutely no extra information as to whom we got it from, nor any indication of the region/country of origin 😕
Overall plant height: 39 cm
Ramicaul: up to 22 cm
Leaves: up to 14 x 5 cm
Flowers: 12 mm

Normally their page is accessible without an account, otherwise I will add the photos here.

Full disclosure I have no idea which species it is, but I looked it up with Google lense and got this:

Acianthera saurocephala

I don't think you can ever definitively know, but this species looks pretty close.

That does look pretty close, other than the color. I wonder if there is a var aurea or var alba of this species??

It also has the form of Stelis maxima but that one is deep burgundy. If it's part of that group, the weird thing about them is that they open in the cool of the morning, then tend to close up later in the day, to re-open the next morning. (Stelis purpurea does that too too) For location, I would guess Ecuador or thereabouts.
