Andinia auriculipetala is most similar to A. cordilabia and A. werneri but can be distinguished by the acute lateral sepals (vs. apiculate), the reniform, hirsute petals proportionally larger (comparable in size to the lip) with the lobes unequal and the sub-cordate lip ciliate toward the round apex, with the basal lobes oblong and touching above the column.
