Discusión taxonómica
This is most similar to A. miradorense and A. potosinum, differing in its epiphytic habit, darker and more lustrous stipes and rachises, and falcate, less deeply serrate, more attenuate pinnae. From A. pteropus and A. pseuderectum, A. harpeodes differs in its non-alate rachises, or rachises adaxially narrowly winged (vs. laterally and broadly winged in A. pteropus and A. pseuderectum).A
