Found in Costa Rica and Panama in cloud forests at elevations around 1000 to 1100 meters as a mini-miniature sized, warm growing epiphyte with slender, erect, laterally compressed above the middle ramicauls with a tubular bract below the middle and 2 to 3 tubular sheaths at the base and carrying a single, apical, erect, coriaceous, narrowly ovate, acute, cuneate to rounded to shallowly cordate into the sessile base leaf that blooms in the late summer through winter on a fascile of .4 to .8" [1 to 2 cm] long, successive single, few flowered inflorescence arising from the base of the leaf through a reclining spathe.

"Pleurothallis instar resembles mostly closely P. eumecocaulon Schltr., but it can be recognized by the ovate leaves and wider sepals and petals. Also, P. eumecocaulon bears a papillose disc located below the middle of the lip, whereas the disc in P. instar is concave and located in the basal half." Bogarin & Karremans 2012
