[3][5] The specific name ingeri honors Robert F. Inger, an American zoologist from the Field Museum of Natural History.

[4] "Niceforo" in the common name refers to Brother Nicéforo María, a missionary and naturalist in Colombia,[4] who collected the type series.

[2] The type series of A. ingeri consists of four specimens, the largest of which (the holotype) measures 27.5 mm (1.1 in) in snout-to-vent length (SVL).

The fingers are long and have relatively small discs and slight lateral fringes; no webbing is present.

The dorsum in preserved specimens is slate black, but the top of head is little lighter, and there are traces of a gray chevron mark in front of the eyes.
