Pleurothallis atrohiata is native to Haiti.

[1] It is found on Massif de la Hotte at elevations of 800 meters.

This was a huge genus, which used to contain more than 1,200 species - the second largest in the Orchidaceae after Bulbophyllum.

The genus name is derived from the Greek word pleurothallos, meaning "riblike branches".

This refers to the rib-like stems of many species.
