Found in Napo and Morona-Santiago provinces of eastern Ecuador and Amazonas department of northern Peru at elevations around 450 to 650 meters as a mini-miniature to miniature sized, hot to warm growing, shortly repent epiphyte with erect, sharply 3 winged, thickening towards the apex ramicauls enveloped by 2 to 3 thin, tubular sheaths at the base and carrying a single, spreading, coriaceous, broadly elliptical to suborbicular, obtuse, cordate below into the sessile base leaf that blooms in the winter and summer on a short, arising through a broad spathe at the leaf base, in a fascile of short, successive, single flowered inflorescence with shorter than the pedicel floral bracts.
"Allied to P casapensis but P erythrogramma only occurs at low elevations. It is closer allied to P discophylla but it has unstriped sepals and a spathulate lip. P erythrogramma is distinguished by the creeping rhizome, erect sharply triquetrous ramcauls, spreading suborbicular leaves and a relatively large, sigle, gaping flower. tThe erect dorsal sepals is long and narrow, the lateral sepals aer connate into an ovate, acute, yellowlamina that is prominently veined in red. The petals area minutely serrulate. The red lip is elliptical and denticulate." Luer 2004
