Aiphanes bicornis is a species of small, pinnately leaved palm which is endemic to Ecuador.

First described in 2004 and known from only two locations, the species name refers to the deeply notched tips of its leaflets, which are said to be evocative of the horns of an antelope.

Stems are covered with grey spines up to 6 cm (2.4 in) long with 5 to 10 millimetres (0.20 to 0.39 in) spacing between nodes.

[1] Aiphanes has been placed in the subfamily Arecoideae, the tribe Cocoseae and the subtribe Bactridinae, together with Desmoncus, Bactris, Acrocomia and Astrocaryum.

[1] Aiphanes bicornis is known from two locations at the base of the Cordillera de Toisan on the western slope of the Andes, in Imbabura Province, Ecuador.
