Bulbophyllum isabellinum Cavestro et J. Champion spec. nov. is simillar to Bulbophyllum gusdorfii J. J. Sm. but differs in close and shorter ovoid pseudobulbs; shorter and elliptic-ovate leaves; shorter and sulcate lateral sepals (not flat), emarginated (neither acute, nor acuminate), yellow orange and tawny, triangular and shorter petals, neither fimbriate nor papillose at apex, a labellum tongue-shaped (not oblong-ovate), shorter with three ridges at base and in the middle, a median ridge very short and inconspicuous.
