Found in Guatemala at elevations around 400 meters as a smallsized, hot growing,myrmecophilous epiphyte with a short rhizome giving rise to orbicular, strongly laterally compressed, rough, red spotted pseudobulbs enveloped basally by brown, papery sheaths and carrying a single, apical, green, fleshy, obliquely elliptical, obliquely rounded apically leaf that blooms on a basal, racemose, peduncle cylindrical, 10" [25 cm] long, successivley single, alternate, several flowered inflorescence with small, scale like floral bracts and carrying non-resupinate flowers.

"This species can be separated from Chelyorchis ampliata by some morphological features: the petals are more or less spatulate, without a marked tab, whereas in C. ampliata they are clearly unguiculate with a sub-orbicular blade; the lateral lobes of the hypochilus are broadly triangular (versus obliquely lanceolate oval); the kidney-shaped epichile is almost as wide as the hypochilium when it is 2 times larger than the hypochilus in C. ampliata; the wings of the column have entire margins (versus clearly denticulate)."
