Archaeamphora longicervia also shows a resemblance to species of the genus Heliamphora in having pitchers with a long neck and upright lid. Of particular note is the similarity between the thick semi-circular structures on the lid of A. longicervia and the large nectar-secreting "bubble" present on the upper posterior portion of Heliamphora exappendiculata pitchers.
