[1][2] Iberoraphidia dividua is known only from one fossil, the part and counterpart holotype, specimen number GZG.RF.7563.

The specimen is preserved as a compression fossil in lithographic limestone, dating to the Lower Barremian age, which was recovered from outcrops of the La Pedrera de Rúbies Formation formed by deposition of carbonate mud in a brackish or freshwater lagoon.

The outcrop is located in the Serra del Montsec region near the town of Santa Maria de Meia, province of Lleida.

[1] Iberoraphidia was first studied by the paleoentomologists James E. Jepson and Edmund A. Jarzembowski from the United Kingdom and Jörg Ansorge from Germany.

Their 2011 type description of the new genus and species was published in the entomology journal Palaeontology.
