Id miss marked ?Pleurothallis

[boltoncs]

I was at Phipps Conservatory last evening and the orchid grower has this plant in bloom. The tag in the plant reads Pleurothallis alligatorensis. That name doesn't exist and the other Pleurthallis in Orchid Wiz or International Species site. There is a species with a name similar but doesn't look at all like this one. It may be difficult to ID but does anyone have a guess?
