Identification. This species is characterized by having intact and persistent cataphylls, narrowly ovate to ovate-triangular (more than twice as long as wide) and moderately coriaceous blades; creamy-white spadices and cucculate spathes. Some specimens had inusual larger blades, Croat 68700 C (35.9 × 6.0 cm), Hammel 16112 (41.0 × 7.0 cm), and Hartman 4685 (31.5 × 7.5 cm); however, the floral characteristics are similar to the rest of the specimens. At the study site, A. cucullispathum may be confused with juvenile individuals of A. ravenii Croat & R.A. Baker and Anthurium sp. 4 , but both species differs due to the deciduous cataphylls in most of the nodes and by its reflexed and brittle spathes.

Distribution and ecology. Colombia, Costa Rica, and Panama. On Cerro Pirre, this species generally grows in low and mid elevation areas, in the semideciduous and evergreen forests, below 1000 m.
