Masdevallia fulvescens belongs to a group of morphologically similar and genetically closely related species, including M. calura, M. reichenbachiana, M. rolfeana and M. schroederiana. It is mainly distinguished from its close relatives by the slightly arched sepaline tube, (a straight funnel-shaped in the other species), which is distinctly compressed laterally.
