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.
