[2] It is endemic to Martinique, where it is found at high-altitude areas including Mount Pelée and potentially most of the Carbet Mountains.

[1] However, examination of new specimens with molecular phylogenetics methods suggests it is truly distinct from the mainland Allobates, and highly diverged from its closest relatives.

[6] Allobates chalcopis was originally described from forested ravines of Mount Pelée at an elevation of about 500 m (1,600 ft) asl.

The current range starts from the transition zone between forest and savanna, the latter being the vegetation type found higher up on the mountain.

[1] However, in light of its disappearance from the lower altitudes due to climate change and the very small remaining range (and the evidence of endemicity), it was reclassified as Critically Endangered in 2021.
