2 varieties have been described:
Anthurium lancea var. ecostatum Croat 2009
The variety ecostatum differs from the typical variety of Anthurium lancea in the absence of the posterior rib (hence the epithet "ecostatum" = without a posterior rib or costa) and in its narrower, non-cordate leaves, as well as in its spadix, which has practically no stipe. Colombia at an altitude of approx. 1800 m.

Anthurium lancea var. lancea (no information)
syn.: Anthurium lancea var. canarense Sodiroi
This variety was found by Sodiroi in the Cañar district of Ecuador. Unfortunately, the type material no longer seems to exist, so no further information can currently be provided.

Etymology:
lancea = lance-shaped

Origin: Ecuador, Colombia, Peru
Habitat:
Anthurium lancea grows terrestrially in shady places and occurs at elevations of 400–2500 m. Plants from higher elevations are described as having more leathery leaves, while those from lower-lying areas are softer, glossier, and more attractive.

Notes:
According to Tom Croat, the leaves of this species turn black as they die. The plants from elevations above 2000 m are an exception; their foliage changes, and the leaves turn yellowish brown as they die.
The plants have a beautiful, evenly ridged surface formed by the parallel leaf veins, which end at the leaf margin.
