It was first discovered in 1993 on Mount Iberia in the Holguín Province, from which it gets its name. Much remains unknown about this small creature. It is part of a closely related Cuban group that contains five additional described species ("E. cubanus", "E. etheridgei", "E. jaumei", "E. limbatus" and "E. orientalis") and at least one undescribed species; most of which are of tiny size, relatively brightly colored and possibly aposematic (at least "E. iberia" and "E. orientalis" have alkaloid toxins in their skin).
